61mm doesn't get any better

It acts more like a 161mm aperture than a 61! Images are sharp as sharp can be, there is really hard to find anything to complain about. If you're starting out with astrophoto or even if you're advanced, or you want to take your gear to mountain climb, it doesn't really matter. This thing is a handy little thing that won't let you down! Easy to handle, easy to carry, mounts to lighter tripods, outperforms all the beginner scopes I had. Also fantastic for daytime landscape photography. Made a picture of a building - not even sure how far away- but hard to see with ***** eyes and it came out so pure and sharp. Here is a shot 50 seconds (no stacking done here) with a DSLR (PENTAX) camera attached to this scope

Beautiful Optics and Extreme Quality for the price

Absolutely a wonderful experience all the way through. I bought my 61II APO as my first "real" optics set for Astrophotography. Shipping was very rapid in comparison to everything else on the market and I had my optics within a couple weeks (I'd honestly say less than two weeks). My god the build quality is to die for. Beautiful coloration and the quality of the materials is top notch. At first I thought I got sent the wrong scope. Everything told me I got something more than what I paid for. Hand written sign off for quality checks, individual signature card for quality control for each piece of the optics, carrying case, the works. 100% earned my LIFETIME business for optics.
