NGC6992 20 hour H-Alpha deep field

[pietervdv]

Hello everyone,

I'd like to share a work in progress of a deep exposure of the supernova remnant NGC6992 in Cygnus.

It's made up from two panels each exposed for 10 hours, so 20 hours so far with 30 min subexposures.

Data was captured over 8 different nights during the past few weeks.

In a couple of weeks I will be at a dark site to hopefully add another 20 hours of OIII, for a bicolour image.

This is just a fast process, the plan is to process it more in depth when all the data has been collected.

Just  levels / curves and panels stitched in PS, no PI tricks  ...

Tech stuff:

Scope: self built 10" f/3.8 astrograph with 3" Wynne corrector

Mount: Mesu 200 Sitech

CCD: sbig st8300 @-14°c with Astrodon 5nm h-alpha filter

Guiding: homemade OAG with Lodestar (5 s guide intervals)

Hope you like the progress so far, thanks for taking a look!

Oh yes that's going to be special,

very sharp and deep,

looking forward to the extra data, as this remnant is very colourful

Well done

That is beautiful! I love the interference patterns on the diffraction spikes too.

Coming along very nice. I think the final version will be something special

Never seen better. This is so strong and yet so delicate.

Very fine detail love the tiny filaments running down the outer spine
