M97/M108 in Ursa Major
Owl Nebula Planetary nebula and inclined spiral Galaxy
Uploaded 4/13/16

This contrasting pair of bright Messier objects just fits in the two degree tall field of this two part panorama - the first time Ive tried this with the 10 inch. The lower round nebula, teal in color is the Owl Nebula - M97, and the two dark "holes" in the object are the owls eyes. Upper right is M108, a very nice inclined spiral galaxy with lots of detail in the larger images.

Surprising was the sheer number of faint galaxies in this field! In 45 minutes integration time for the L channel, I find obvious tiny distant galaxies peppering this image down to around mag 18 and fainter. Three images are presented here of the same shot. The top is a conventional image showing the sky normally. The second image is a negative which when viewed on a computer screen more easily shows the hordes of faint galaxies. The third image Ive circled in red each galaxy so you can see just how many there are! The final fourth shot is a close up on one of the background galaxies which shows spiral detail.

A negative image of the faint 15.5 magnitude galaxy UGC6211 which appears in the lower right corner of the original image. Nice spiral details show in the Sb galaxy - a barred spiral.
