                                                                My #1 choice for Astrophotography

                                                                The views and images that this Scope produces are simply breathtaking. After trying my hand at astrophotography with an ES doublet for about a year and a half, I decided it was time to upgrade to a triplet with the high quality FPL53 glass for a smoother viewing experience. This model was my #1 choice. The Carbon Fiber body is a cool added bonus, as it’s a few pounds lighter than this Scopes' non CF counterpart. I use my twilight I mount if I want a quick set-up for basic viewing. If you plan on doing astrophotography, I would recommend a GoTo equatorial mount.
