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. lolĪ great lens at a great price.The biggest draws of the little RedCat 61 are its image quality, compact size, and robust focuser. But I have that phobia with all EPs with fold down rubber eyeguards. The rubber fold down rubber eyepiece seemed pretty good quality, though I wouldn't want to fold it up and down too many times for fear of it tearing. Performs a tad better than the EW 6mm in that regard. It did get a little more challenging to get my eye in the right position to avoid blackout at that high mag. ![]() Barlowed in my 2" ED 2x up to 266x and it held up with clear views. I'm pulling 133x mag out if this lens and it's a sight to behold. Sharp views, nice fov, good eye relief, well made, and it won't break the bank. I recently picked one of these up and its been worth every penny. Please also note that on the barrel, these are labeled as "Ultra Wide" but we call them "Enhanced Wide Angle" to distinguish them from our 80-deg UWA eyepieces.ġ out of 1 people found this review useful 4.0 Affordable lens that works great! Pros: Order one today to start enjoying wide and comfortable high-power views of Saturn’s Rings, Jupiter’s Bands, icecaps on Mars, and more! The generous field of view of this eyepiece also allows for wide views of the Moon and deep-sky objects at moderate to high magnification. The insert tube is smooth-sided and is threaded for standard 1.25" astronomy filters. All lens edges are blackened for superior contrast. The long eye relief allows for a comfortable viewing distance. All air to glass surfaces have a multi-layer coating (so these are fully multi-coated, even though the barrel imprint may say "multi coated") for maximum light transmission. This high quality eyepiece features a 6-element design that offers superior sharpness. With features generally found in more expensive eyepieces, this ocular will escalate the joys of viewing with high-contrast views and amazing color correction. This 1.25" Agena enhanced wide angle eyepiece is sure to provide many “ooohs,” “ahhhs,” and “wows” from those who take advantage of its generous 66-deg field of view. ![]()
