M27 Dumbbell bicolour (24 hr exposure)

Recommended Posts

Hi all,

Last week I've put together some of my data made the last couple of months to compose this bi-colour image of M27. Quite tricky to proces due to the high dynamic range of the object, quite a pain to tease out the faint outer details without making the image look to forced. I started the processing job from scratch a couple of times, but settled with this version for now. The h-alpha data was acquired from my heavily light polluted backyard, the o3 data I acquired during an astro holiday in Southern France (Provence) under pitch black skies late August.

Thanks for checking them out.

Regards,

Pieter

 

Some details of my gear:

Scope: 10" f/3.8 homebuilt Astrograph with 3" Wynne corrector

CMOS: ASI-1600 MM Cool (-10°C)

Filter: Astrodon 5nm h-alpha / Baader 4,5nm o3

Exposure: 24 hours in 5min subframes (15 hrs h-alpha / 9 hours o3)

Mount: Mesu200

That has to be the best M27 I have seen. Stunning level of detail and taking it so far out from what we normally see in M27 Images. Amazing!

Brilliant!

Any details or pics of your homemade scope?

Thank you! The scope is based on a 250 mm f/4 premium grade mirror, all other components are custom designed/made parts. I have been very happy with it! There are some pictures of the design and build here:
