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.

This picture was taken arbitrarily in Canes, looking for a test object to verify the corrections I did to the optical train. In the previous image (M3) I noticed some tilted focal plane. That was due to an extension ring which was not tightened enough. The main galaxy here is NGC5353
This is a group of galaxies in Leo, the Lion constellation that dominates spring nights. M65, M66 and NGC3628. At distances of 35, 42 and 37 Million light years, they form a fysical group in space Tidal forces rip apart the extremities of NGC3628. The smallest galaxy identified in this image is PGC1423398 at a distance of 2 Billion light years: so glad those fotons travelled that distance in space & time only to get caught in my camera!!
