An image of the surprisingly nice galaxy M109, located near Phecda, one of the bright stars of the Ursa Major’s bowl. Imaging was done with the C11, using the Starizona F 7.2 reducer, and the Nikon D750. Unfortunately, the image format setting in SGP was set to “FITS”. That resulted in strange, Black/White images with lots of problems! I could salvage the 27×300″ images a bit but the end result is a bit disappointing, it’s not a color version to start with. ..
After cleaning & collimation, I tested the C11 with the Starizona F 7.2 reducer, the ASI183mm (way oversampled obviously), and guiding using a simple external 8×50 guider and the ASI290MC. Just as a test not bad. I’m not convinced the mirror shift did not have influence in this image. Focusing was a pain, needed to be done manually.
Deep in space – 50 million lightyears away – lurks this cluster of galaxies called Abell 2199. At some area’s you will find more galaxies then (foreground) stars. Actually the whole image gives a fuzzy appearance, not only because the seeing was not very good and my processing skills need improvement, but also because lots of “stars” are actually fuzzy galaxies.
Taken on May 5th, 6th, 7th and 8th in total 280 minutes (4hrs 40minutes) of data.
Would you count the number of fuzzies in this image? I tried a bit and came to 200 galaxies, not counting suspicious stars. The brightest one is NGC6166 at 11th magnitude, most small galaxies are magnitude 16th.
Seeing conditions were not very brilliant during the capture and tracking went off sometimes (for unclear reasons most likely declination backlash).
With M3 (May 4th) , NGC5053 (May 5th) and this image (May 6,7 & 8th) , I broke my personal record with imaging 6 nights in a row.
