I've been using this scope since January 2016 and have since added two other scopes to my staple. This one is still my favorite. It's extremely light and rides well on my AZ-EQ5 (30 lb. payload limit) even with a cooled astrocam, filter wheel, guide scope, guide cam and coma corrector. Even 900 second guided subs on a medium payload mount are easy on a windless night. The focal length is just right for larger galaxies as well as most nebulae (I've even taken some decent shots of Jupiter with it) and - unless you've got a RASA, Hyperstar or Epsilon - the speed can't be beat. I've used it to image some seriously dim targets such as CTB1, Purgathofer-Weinberger 1 (PuWe1) and Fererro 6 (Fe6) and it's given me great results. It also pairs really well with the Explore Scientific HR Coma Corrector. I would suggest one modification though: Add an aperture mask to cover the mirror clips. I made one out of black foam board and it's helped to give me nice, sharp diffraction spikes without any odd "flaring" around bright stars. (Posted on 12/16/2018)

I bought this scope to do Astrophotography and have been very happy with it. The carbon fiber tube makes this scope easy to mount. The focuser seems to be of good quality Works great with the ES coma corrector. Once I got the spacing right I have round stars all the way to the edge. Collimation can be a little finicky but that’s what you get with fast optics. (Posted on 10/26/2018)
