A quick outing before the weather got bad as a tropical storm hits from the Gulf. I wanted to test the new T-adapter fittings I got for the AT60ED to attach the camera instead of using the 1.25″ eyepiece adapter, like I had to do for the first light images.

First Light – AT60ED
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.
