I've been after a short focal length refractor for wide field deep space imaging and I have been looking at so many scopes. For a while I have been using standard camera telephoto lenses due to being without a scope for a while.

The RedCat would suit my style of astrophotography more than any other, but I'd like to know if it is worth buying over a similar focal length standard camera lens?

As an owner of the Whitecat 51 (Redcat was out of stock and Spacecat hadn't been released yet) I have to say yes, it's worth it over a camera lens.

My main camera is a Pentax K-1 and I mount the whitecat on either a Losmandy G-11 or Explore Scientific IEXOS-100.

I absolutely love the FF/Whitecat combo. I also have the following lenses (amongst others), 300mm f/4, 70-200 f/2.8, 150-450 f4.5-5.6. None have them have the flat field, pinpoint stars, and lack of CA that the WC has. Not to mention that I can use 2" Astronomical filters with it.

Here's a few samples of the combination:

M31 45x60sec


M42 60x120sec Optolong L-Enhance filter used.

Beautiful images! What Bortle area were those taken from if I may ask?

Thank you.

M31 was shot in Bortle 7/8 skies

M8/M20 were shot in Bortle 6/7 skies

The Orion Complex was shot in Bortle 5 skies with the Optolong l-Enhance filter. All unguided.
