Description

First light for my new Astro-Tech 130mm f/7!  Perhaps I was a bit too excited with the extra focal length compared to my smaller camera lenses, and picked a galaxy still too small. I think this pair would benefit from greater fl yet, but still very happy to get this capture. I was using the reducer as well, so only around 728mm. I haven't tried not using thew reducer/flattener. Unlike my 500mm, the stars are nice and round! However they still seem kind of big, was hoping they'd be a little tighter. It is possible my focus drifted a bit, I had not got the EAF hooked up yet, and only refocused once during the night. So with the new EAF maybe can get that a little better. Oh and I never got around to taking matching darks, so dithering and linear fit clipping was my main noise reduction here. And the noise was low enough I only applied a very light NR in post.
