NGC4490/85 with ST-237

This image of NGC4490 and 4485 was taken with my guide scope. The guide scope is a Borg 45mm ED (that's right, a 45mm aperture). The result was better than I expected, so I thought I would post it. A stack of eight 10-minute images, with some sharpening to tighten up the stars.

The C14 with ST-10XME was imaging and self-guiding, so I was able to image with the 45ED scope and ST-237 for long exposures. There is a small amount of flexure in this system, but not enough to show up in 10 minutes.

You can see my setup, with the little 45ED Borg at the left of the C14 tube, here:

those tiny little borgs are something, aren't they? I used to have a 50mm f/10 ED one that I used for h-alpha solar viewing. I had to sell it to finance some other toys I use more, but playing around visually, I was amazed at what a high quality 2" scope could pick up...
