Sh2-308 - The Dolphin Nebula

#1

Post by cmassa »


Here's the last target imaged with my 10" f/4 Newtonian, I still have many others to process though. My new telescope has brought in a lot of clouds and rain to California so I haven't gotten to use it much yet.

This is 21 hours of 20 min subs in February 2020. It's a low target, mostly below 25 deg elevation for me. Imaged in Ha and OIII.

Mount: Paramount MX+
Camera: Atik 383L+ with Astrodon filters
Scope: TPO 10" f/4 Newtonian
Acquisition: Sequence Generator Pro
Processing: PixInsight

Thanks for looking,
Chris

Hi Chris. Just wow. This is a great capture of the Dolphin Nebula. Excellent contrast, sparkly stars, great color in the nebulosity, and the shell is quite sharp. Thanks for sharing this on here Chris, and congratulations on winning the TSS APOD Award today.

Great image Chris. Not only can you see the dolphin, but also the shell of diaphanous gas that composes the nebula. Just superb. When I first saw it I thought it must be CGI.
