I’m a big fan of ultra-portable setups like this, but make no mistake, a configuration like this is best for capturing WIDE field images. You can pick up an ASI120MM Mini and a little guide scope like this for about $250 (all in). Sticking with the lightweight motif, you can see the tiny 32mm guide scope I’ve mounted to the cat saddle. I’m sure the AM5 will be a popular choice if you plan on traveling with the rig. In terms of mounting, a GoTo mount in the 20-30 lb payload range is more than enough. Guide Scope: William Optics Uniguide 32mm.My Astrophotography Setup featuring the RedCat 61. The Set UpĪs you can see, it’s RED overload here on the ZWO AM5 mount – some may say it’s even TOO red. These tiny little guide scopes do a great job and add very little weight to the overall setup. I recommend a lightweight 30mm guide scope like the ZWO 32mm Uniguide or a ZWO 30mm F/4 guide scope. As this is primarily a deep-sky astrophotography telescope, adding a small guide scope and camera to the configuration is something you’ll want to do early on. I am happy to see that the ‘cat saddle’ dovetail bar is included in the package. Like most other William Optics telescopes, a dew shield cover and built-in ‘star spikes’ Bahtinov mask are also included.

Included with the RedCat 61 are the red tube rings, a cat series handlebar for attaching other accessories, and a dovetail bar. It always includes a stitched, padded bag, warranty, and yes, sometimes even cat stickers. In terms of overall presentation and attention to detail, all of the William Optics stuff is really slick. Let’s have a look at the core specs of this refractor telescope. The WIFD internal focuser design is also available on the latest GT 81 APO, and I think William realizes he has a winner with this one.Īs I will mention a little further down this post, the position of the focuser knob is something you will need to get used to. This design redistributes the overall weight of the telescope and can help you achieve a better balance of your astrophotography rig.ĭiagram showing the new WIFD internal focus design on the RedCat 61.
You can view and confirm your focus distance using the numerical display via the small window on the side of the RedCat 61. The center focuser was designed for precise internal sliding of fixed optics to prevent image shift. This means that you can now use a traditional autofocuser with this scope, like the popular ZWO EAF. The biggest change to this Cat is one that I think will make people who may have ignored the first version take notice. The helical focuser is gone, and it now uses the patented WIFD internal focus design.

The RedCat 61 mounted to a portable star tracker (Star Adventurer GTi). This places the RedCat 61 in the small equatorial mount category or even on a well-balanced star tracker setup like the Star Adventurer or GTI. The scope weighs just 7.5 pounds, and you can realistically tack on another 3-4 pounds for camera gear. The RedCat 61 is a practical astrophotography telescope for those using a DSLR, Mirrorless Camera, or a Dedicated Astronomy Camera. In the past, when using a full-frame camera, I’ve had to crop about 5% of the frame away using the RedCats. I expect to do the same with this one. You can attach your full-frame DSLR, mirrorless, or dedicated astronomy camera to the T-mount and enjoy a 46mm image circle. Like the RedCats before it, the 61 uses FPL-53 glass in a Petzval lens design. The moon is also in play, but planets are just too small for this scope. The RedCat 61 has a focal length of 300mm and a focal ratio of F/4.9. This means it is best used for wide-field nebulae projects and only the biggest galaxies. The William Optics RedCat 61 is Available at Agena Astro. However, these premium features come at a cost.Īt the time of writing, the William Optics RedCat 61 is listed at a retail price of $1,600 USD. The biggest draws of the little RedCat 61 are its image quality, compact size, and robust focuser.
