CTB-1 and Sh2-140 h-alpha marathon

[pietervdv]

Hello everyone,

Today I processed two of my images from my last imaging trip in France (taken at Domaine de La Blaque),

on my way home I stopped at Olly P. his place for 3 more nights.

The weather during the 2 week trip was exquisite (12 clear nights in a row!), last

part of the trip coincided with the moon's return. Luckily I still had these 2 on my bucket list for h-alpha...

The equipment used was my 10" f/3.8 newton on a Mesu200 mount, the ccd was an sbig st8300.

Both images made with an Astrodon 5nm h-alpha filter using 20 & 30 min subexposures.

The first one CTB-1 (Abel 85) is an extremely faint supernova remnant in Cassiopeia.

Exposed over 10 hours.

The second one probably also lesser known: Sh2-140 in Cepheus, the shock front top right shows some very interesing Herbig Haro-objects.  Exposed for 9 hours

Comments always welcome!

Thanks,

Pieter

NIcely done on both of these - CTB1 is a real faint one, so a top image!

Particularly nice images but for me, CTB1 is outstanding.

A test of your equipment that's for sure.

Great couple of images Pieter, also for me the one of CTB-1 is the pick.

Truly outstanding on such faint targets. I love both of these. Your home made scope is really singing and should inspire the professionals to try harder! Brilliant imaging.

Outstanding Pieter,  CTB-1 just takes my breath away, Sh2-140 is growing on me.  Also managed a google for Domaine de La Blaque,  looks like you had a good couple of weeks,  thank you for posting.

a couple of superb images, CTB-1 (Abel 85) is a fantastic capture! 30 minute exposures, obviously a very well aligned/guided set up!
