First Light Images for a new Astro-Tech AT60ED telescope. Nice 360mm F/6 doublet with FPL-53 synthetic fluorite and Lanthanum lenses. I bought the 0.8x Reducer/Flattener that goes with it, too. It gives you a 288mm F.L. at F/4.8 with that combo. Resolution is still good at 1.72 arc sec/pixel with my camera.

These objects are the Eagle Nebula, Trifid and North America Nebulae.  All were taken with a QHY183C camera at gain 20, -15C cooling and a cheap no-name UHC filter from a metro area, Bortle 7-8 zone.

The North America Nebula. 9 x180 sec, QHY183C at Gain 20, Offset 0, -15C cooling, UHC filter, Astro-Tech AT60 ED at F/4.8.
