Galaxy Collage April 2021

After every galaxy season I try to update this. I was able to scale them appropriately according to relative angular size. Most were taken at an image scale of 0.65"/pixel, so even though I had to down sample the final image by 50% to make the file size more manageable, there is still some decent detail in many of the galaxies in full resolution. It includes all of the major types: spiral (barred and unbarred, edge on and face on), elliptical, lenticular, irregular, peculiar/warped, interacting/merging, flocculent, Seyfert, starburst, dwarf, ring, double ring and polar ring.

This is from over a decade of imaging with different scopes and cameras, so quality and detail will vary. All were imaged from Bortle white(SQM 17.8 mag/arc-sec2) zone in NJ, USA.

Equipment used:
CCDs: Meade DSI Pro II and III, QSI 540 and 640 wsg
Guide camera: SX Lodestar
Telescopes: Meade 10" LX200R @ F/10 and Celestron 9.25"Edge @ F/10 or F/7.
Optec TCF-SI focuser
Mounts: LX200 fork and Avalon M Uno
Software: APT, Maxim LE, PHD, CCD Stack, Photoshop CC

other sizes: small medium large original auto
