Who has brought us the best Owl Nebula, also known as Messier 97 or NGC 3587? Vote for your favorite from the following entries:

SMigol



Here is my image showing the Owl Nebula (M97). As a widefield image, it also shows M108.
Taken on two nights May 12 & 14, 2013 at a local dark sky site (Montebello OSP) N 37 19 32, W 122 10 44.

20 subs at 1200 seconds duration at 100 ISO for 6.7 hours of integration.

Telescope: Stellarvue SV4 with SSF6 flattener and IDAS LPS-P2 filter
Camera: Modified and cooled Pentax K10D DSLR
Guidescope: SV70ED with SSAG
Mount: Losmandy G11 with Gemini 2

Guided and Calibrated by Maxim DL
20 Darks (two sets of 10 to match the temperatures of different sessions), 40 Flats (20 for each session), 256 Bias

Stacked with DSS. Processed with PixInsight.

Would have liked to drive the background a bit lower, but this would have lost many of the faint galaxies.
