The image shows the North America nebula, NGC 7000 on the left, with the Pelican nebula, IC 5070 close by. Also in the image, in the lower right, is the Butterfly nebula, IC 1318. The bright star just above centre is, of course, Deneb.
The image is a stack of 15 x 2min exposures taken on an a Canon EOS400D with a Sigma 105mm f/2.8 lens at f/2.8, ISO400. The camera was guided using PhD Guiding by the Lodestar through the Equinox ED80. Images were acquired and processed using ImagesPlus 3.0, with final tweaking done in Adobe Lightroom.
Just for once, the autoguiding worked flawlessly, and the end result shows it was worth the effort. Admittedly it’s a relatively easy target, but it’s nice to get something worthwhile for a change!
Well, while M3 was being captured, the optics on both scopes started to dew up. I ended up with 10 x 2min images which were processed to give this image. It’s not as sharp as I’d like – more work on focusing required – but at least the guiding worked 🙂
I also had a go at setting up and using the Starlight Xpress Lodestar autoguider that I recently bought. It’s certainly much more sensitive than the ToUcam for this purpose, but I still didn’t get the system tracking as I would have liked. More experimentation needed!
The faint smudge visible below and to the right of M35 is another open cluster, NGC 2158.
