Thank you FLO I recieved my 2nd order Redcat 51 yesterday august 28, 2020. I will try to use this scope once the rainy season ends in the Philippines. Once again am very pleased with your services. I have star adventurer pro from my last order from your store: maybe I will order again next time a GOTO EQ MOUNT. I will enjoy and learn some first some basic astrophotography with SA Pro and RC51 . 5 stars... Thank You

William Optics v1.5 RedCat

I bought this along with the Ioptron Sky Guider full package including the Ipolar. Not had many opptions for test but the Red Cat meets all my expectations. Very small and lightweight, the integrated focus mask is great and enables pin sharp focus, love the focus on the redcat just like many manual focus prime lenses. Along with the sky guider this is an excellent light weight wide field astro photography system, easy to set up and take excellent photo's, just need more clear nights to continue to explore what this set up is capable of.

Really Good

Looks good and it is really good .Tried it out last night on the crescent Moon.The field of view is big enough to find the target without too much difficulty (clouds) and the focus control is a pleasure to use. Need some dark nights now to test it out on some Galaxies, etc.

Just what I needed
Tuesday, 21 January 2020  | 

I have been using the RedCat (from FLO) for a month now when the weather has permitted, and leave it permanently attached to my unmodified EOS 6D - it then lives in a camera bag. I have been blown away with the image quality across the frame, and the icing on the cake is that the size and weight are such that it operates a treat on the Sky Watcher Star Adventurer mount. Admittedly, running without guiding results in approx 40-50% light frame rejection rate,but that is more than compensated by the time lost in setting up and aligning a less portable set up. The tube oozes quality and I really like the ability to attach a screw-on 55mm photographic filter to protect the objective - purists may pour scorn, but I don't think its presence will seriously detract from the images I take. The focusing scale around infinity is extremely precise and enables focus to be obtained to the point where only tweaks are required. Expensive, yes, but well worth every penny in my book. Nice Christmas present too.

RedCat51 looks amazing
Wednesday, 16 October 2019  | 

The WO RedCat51 arrived quickly from FLO, as usual, and was well packaged. The scope itself looks fantastic and looks and feels a quality item. Iíve had one chance to use it on my EQ6-Pro (overkill, I know), and I love the scope already. The focussed is smooth and holds focus really well, and the Bahtinov mask built into the dew shield is inspired. It was a full moon so there were awful gradients in my M31 image, but the stars looked good all the way out to the edge of the frame of my Canon 100D. Plate solving is a breeze with the roughly 5x3 degree field, and guiding is a doddle (my guide scope has about the same FL as the RedCat51!. Iím looking forward to some darker nights (and the arrival of an Optolong L-enHance filter) to see what itís really capable of.
