Really? Really. Since 2008 when I purchased my first (ever) refracting telescope intended for astrophotography (Borg 77 EDII @ F/4.3) I have collected many Borg items purchased from Astro Hutech (Ted Ishikawa was always very helpful). Namely, after Borg 77 EDII with F4 Super Reducer (#7704) I got Borg 45 EDII with #7866 triplet reducer. Then I got Borg 71 FL with new #7870 triplet multi super reducer, #7887 0.85x DGL reducer and #7878 yet another triplet super reducers to be used for narrow band imaging with a 3rd party achromatic telescope and various CCD cameras. Last (but not least) lens was Borg 50 to be used as a guider (perfect lightweight and compact). It’s said that one image is worth a thousand words so here we go (it’s just a part of my collection that I was able to locate):
Borg scopes are very good performers (taking into account how fast they are) and perfectly lightweight. The weakest link in the imaging train, from an astrophotographer’s perspective, are all of the helical focusers. For AP be sure to get FTF instead!
