Choosing a filter wheel for a mono camera comes down to how many filters you need ready to hand, what is included, and whether your telescope can reach focus with the wheel installed. I rank the Astromania nine-position LRGB wheel first for its larger capacity and bundled filters, the five-position LRGB wheel as the more compact all-in-one option, and the five-position wheel without filters for buyers who already own compatible filters or want to choose their own.

The tradeoff is straightforward: more positions offer room to keep extra filters mounted, but they do not make a camera or telescope more compatible. Both five-position models call for substantial inward focus travel, and the nine-position model is also limited to 1.25-inch filters and accessories. I’d check the optical path and available back focus before choosing based on capacity alone.

Key Takeaways
- Best capacity and included set: The nine-position wheel holds up to nine 1.25-inch filters and includes luminance, red, green, and blue filters.
- Best compact LRGB bundle: The five-position LRGB wheel carries four filters, leaving a spare position without taking on the nine-position wheel’s capacity.
- Best for existing filter collections: The unbundled five-position wheel lets buyers install their own compatible filters and includes several adapters.
- Focus travel can decide the purchase: The two five-position models specify 20 mm and 23 mm of inward focus travel, respectively.
- All three are manual 1.25-inch choices: Buyers seeking larger filters, motorized control, or a stated mono-camera-specific connection should verify fit or look elsewhere.

More Details on Our Top Picks
Astromania 1.25-Inch 9-Position Telescope Filter Wheel with LRGB Filter Set
This is my lead pick for a mono-camera setup that benefits from keeping several filters mounted and ready. Its nine 1.25-inch positions exceed the five-position alternatives by four slots, while the bundled luminance, red, green, and blue filters provide a starting point for LRGB imaging. A click-stop mechanism makes it easier to select a position without removing the camera or eyepiece, and the described light-tight interior is intended to limit stray light inside the wheel.
Compared with the five-position LRGB model, the main gain is room to leave more filters installed, not a different core LRGB set. That extra space may suit an observer who expects to add filters, but it is not a reason by itself to buy a larger wheel if four filters cover the planned imaging workflow. The product is designed around 1.25-inch filters and accessories, so owners of larger filters should skip it unless they have a compatible conversion plan.
Its stated 42 mm T-thread connection is useful information for planning an imaging train, but buyers still need to confirm the thread, spacing, and focus position against their camera and telescope. The listed weight is 1.3 pounds, a meaningful addition to a small imaging rig. Compared with the unbundled five-position wheel, this is the more ready-to-start option; the bare wheel makes more sense only when a buyer already owns filters and prefers to avoid a supplied set.
Pros:- Nine click-stop positions hold more filters than either five-position option.
- Includes luminance, red, green, and blue filters for an LRGB starting set.
- Light-tight interior is designed to reduce stray light.
- 42 mm T-thread connection is specified for imaging-train planning.
Cons:- Limited to 1.25-inch filters and accessories.
- At 1.3 pounds, it adds more weight than the listed five-position wheels.
- Buyers still need to check spacing, focus, and camera compatibility.
Best for: Mono-camera owners who want an included LRGB set and expect to keep additional 1.25-inch filters mounted for different targets or imaging sessions.
Not ideal for: Anyone using filters larger than 1.25 inches, seeking motorized filter changes, or working with a telescope that cannot accommodate the wheel’s connection and added optical-path requirements.
- Filter size:1.25 inches
- Filter capacity:9 positions
- Included filters:Luminance (IR cutoff), red, green, and blue
- Material:Aluminum
- Connection:42 mm T-thread
- Weight:1.3 pounds
- Photo filter size:32 millimeters
- Model number:SKU_AM_FW1M9LRGB
Our verdict“I’d choose this for the most room to keep 1.25-inch filters installed, provided the extra size and connection suit the imaging train.”
Astromania 1.25-Inch 5-Position Telescope Filter Wheel with LRGB Filters
This model is the more restrained choice for a mono camera when four supplied LRGB filters meet the immediate need. The wheel has five positions and includes red, green, blue, and luminance, leaving one position available for another filter. That is less capacity than my overall pick, but it avoids paying for space a buyer may not use and remains a practical way to switch filters without taking the camera off the telescope.
Its two attachment options—a 1.25-inch nosepiece or T-thread—give it a different fit advantage over the nine-position model, which lists a 42 mm T-thread connection. The aluminum body and multi-coated filters are appealing details, but they do not remove the main fit check: the product description says it requires an additional 20 mm of focus travel. A telescope or imaging train without that inward travel may not reach focus, no matter how suitable the LRGB set looks.
Compared with the other five-position wheel, this is the better pick for someone who wants filters included and does not need the other model’s stated eyepiece and T2 camera adapters. On the other hand, a buyer who already owns filters may get more useful included hardware from the unbundled wheel. I would also verify the exact T-thread and camera-side spacing before ordering; the listing gives attachment methods but does not spell out every camera configuration.
Pros:- Includes red, green, blue, and luminance filters.
- One extra position remains beyond the four supplied filters.
- Offers both a 1.25-inch nosepiece and T-thread attachment.
- Aluminum construction and multi-coated filters are specified.
Cons:- Requires an additional 20 mm of focus travel.
- Five positions provide less room than the nine-position model.
- The supplied information does not confirm fit for every mono camera.
Best for: Mono-camera users who want a four-filter LRGB starter set, a spare wheel position, and a choice between nosepiece and T-thread attachment.
Not ideal for: Users who need more than five installed filters, already own a complete LRGB set, or cannot spare the specified 20 mm of focus travel.
- Filter size:1.25 inches
- Filter wheel positions:5
- Included filters:Red, green, blue, and luminance
- Material:Aluminum
- Attachment options:1.25-inch nosepiece or T-thread
- Additional focus travel required:20 mm
- Item weight:14.8 ounces
- Coating:Multi-coated
- Exposure control:Manual
Our verdict“I’d pick this over the nine-position wheel when a compact five-slot layout and included LRGB filters matter more than expansion room.”
Astromania 1.25-Inch Telescope Filter Wheel
Unlike the two bundled models, this five-position wheel is aimed at buyers who already have compatible filters or want to select them separately. Its main draw is the included adapter package: a 1.25-inch eyepiece adapter, a 1.25-inch nosepiece, and a T2 camera adapter. Numbered positions also help identify where a filter sits in the wheel, which can make manual changes easier to track during a session.
For mono-camera imaging, the absence of filters is both the point and the drawback. If a buyer has a preferred LRGB set, this wheel avoids duplicating it; if not, the nine-position and five-position LRGB bundles are more straightforward routes to a basic color workflow. It is also described for visual observing and astrophotography, giving it broader stated use than a camera-only accessory, although exact fit remains telescope-dependent.
The key limitation is its stated requirement for 23 mm of inward focus travel, three millimeters more than the five-position LRGB model. That difference may matter for a telescope with little focus range, so I would check the assembled optical path before choosing this wheel for its adapters. Its listed weight is lighter than the nine-position model, but capacity remains five filters and the product does not include the filters needed to fill those positions.
Pros:- Includes a 1.25-inch eyepiece adapter, nosepiece, and T2 camera adapter.
- Numbered positions make it easier to track filter selection.
- Supports stated visual-observing and astrophotography uses.
- Lighter than the listed nine-position wheel.
Cons:- Filters are not included.
- Requires 23 mm of inward focus travel.
- Offers five positions, fewer than the nine-position model.
Best for: Buyers with an existing 1.25-inch filter collection who want a manual five-position wheel with eyepiece, nosepiece, and T2 camera adapters.
Not ideal for: Beginners seeking a ready-made LRGB set, users who cannot reach focus with 23 mm of inward travel, or anyone needing more than five filter positions.
- Filter positions:5
- Filter compatibility:1.25-inch telescope filters
- Included adapters:1.25-inch eyepiece adapter, 1.25-inch nosepiece, T2 camera adapter
- Focus travel required:23 mm inward
- Weight:13.37 ounces
- Filter inclusion:Filters not included
- Intended uses:Visual observing and astrophotography
- Filter switching:Manual
Our verdict“I’d choose this wheel when existing filters and the supplied adapters are more useful than an included LRGB set.”
How We Picked
I compared these three options as tools for a mono-camera imaging train, rather than treating any filter wheel as a universal accessory. My ranking weighs filter capacity, whether useful LRGB filters come in the box, connection flexibility, included adapters, and the stated focus-travel requirement. Those details affect whether a buyer can build a working setup without replacing existing filters or discovering a mechanical fit problem after purchase.
The nine-position LRGB model ranks first because it combines the largest stated capacity with a supplied four-filter color set and a light-tight interior. The five-position LRGB model ranks next for people who want a smaller wheel with the same basic color set and two attachment options. The bare five-position wheel earns a place for buyers who already have filters and value its included adapters, but it does not provide the same ready-to-image bundle. None of the supplied descriptions establishes motorized operation, exact camera clearance, or universal telescope compatibility, so I treat those as questions for buyers to verify rather than assumed benefits.

Factors to Consider When Choosing Filter Wheels And Filter Sets For Mono Cameras
I’d settle the mechanical questions before choosing between an included filter set and extra wheel capacity. A mono camera needs compatible filters and a workable optical path; a filter wheel cannot fix a mismatch in filter size, connection, or focus range.
Match filter size to the wheel and camera train
All three picks are built around 1.25-inch filters, so begin by checking the size of the filters you own and the clear aperture needed by your camera setup. The nine-position model also lists a 32 mm photo-filter size, but that figure should not be treated as proof that every filter or camera combination will avoid obstruction. Compare the wheel’s connection and openings with the camera, telescope, and any adapters you plan to use. If your existing filters are larger, these options may not suit your imaging train.
Choose capacity for the filters you will actually use
The nine-position wheel is the clear choice for buyers who want more filters mounted at once, especially if they plan to expand beyond the supplied LRGB set. The five-position LRGB model holds four supplied filters and leaves one place free, a simpler arrangement for a basic imaging workflow. The unbundled wheel also has five positions, but its advantage is using filters you already own rather than providing a starter set. Capacity only helps when the installed filters match your imaging plans.
Check focus travel and connection details
Focus compatibility can outweigh every other feature. The five-position LRGB wheel lists a need for 20 mm of additional focus travel, while the unbundled five-position model calls for 23 mm inward travel. The nine-position listing does not provide a comparable travel figure, so check its mechanical length and your telescope’s available focus range rather than assuming it needs less. Confirm thread type, adapter order, and available back focus with the assembled camera train before buying.
Decide whether a filter set is useful or redundant
The supplied LRGB filters make the first two wheels easier to approach when starting a monochrome color-imaging setup. They are less valuable if you already own a suitable set or need a different filter combination. In that case, the bare five-position wheel and its adapters may be a better match. Check what the luminance filter does and whether each included filter fits your intended camera and targets; a bundle is only a benefit when its contents work with your setup.
Account for manual operation, weight, and mounting
These products are described as manual wheels, so filter changes require turning the wheel rather than issuing a motorized command from imaging software. That may suit visual use or a straightforward session, but buyers planning automated sequences should seek a model with explicitly stated motorized control. Also factor in the listed weight: the nine-position wheel weighs 1.3 pounds, while the two five-position listings are lighter. A compact telescope or camera mount may make a lighter, smaller assembly preferable.
Frequently Asked Questions
Which of these filter wheels is the best starting point for a mono camera?
I’d start with the five-position LRGB model if four supplied filters cover the planned workflow and the 20 mm focus-travel requirement works with the telescope. The nine-position option suits buyers who want more filters installed, while the unbundled wheel makes more sense if a compatible filter set is already on hand. None should be treated as universally camera-ready without checking connections and spacing.
Do any of these products include a complete LRGB set?
The nine-position wheel and the five-position LRGB wheel both list luminance, red, green, and blue filters. The five-position wheel without a filter set does not include filters. Before buying a bundle, confirm the filter size and whether the included set matches the intended imaging setup; the supplied descriptions do not establish that every mono camera will work with every listed configuration.
Why does focus travel matter when adding a filter wheel?
A wheel adds length between the telescope and camera, which changes where the camera must sit to reach focus. The five-position LRGB model specifies 20 mm of additional focus travel, and the unbundled five-position model specifies 23 mm inward. I’d check available travel with the full set of adapters installed. The nine-position listing gives no comparable measurement, so its fit also needs confirmation.
Is the nine-position wheel automatically better than a five-position model?
No. Its extra four positions help if you want several filters installed at once, but they may add unnecessary size and weight for a basic LRGB setup. A five-position wheel can be a better fit when four filters and one spare slot are enough. I’d favor the nine-position wheel for expansion room and the smaller options for simpler filter needs or existing accessory arrangements.
Can I automate filter changes with these wheels?
The supplied details describe manual filter switching and do not state that any of these wheels has a motor or software control. I would not buy one expecting automated filter changes. If unattended imaging sequences are part of the plan, look for a wheel that explicitly specifies motorized operation, compatible control software, and a suitable connection for the camera system.
Conclusion
For a mono-camera owner who wants room to grow, I’d choose the Astromania nine-position LRGB wheel, after checking its 1.25-inch limitation, weight, and fit. Buyers who want a simpler starter bundle should look to the five-position LRGB wheel, provided they can spare 20 mm of focus travel. If filters are already in the drawer and adapters are the priority, the unbundled five-position wheel is the more tailored option, although its 23 mm inward-focus requirement deserves a careful check. In every case, I’d confirm filter size, connection, and focus compatibility before choosing on capacity alone.
