Soul Nebula IC1848
« on: Oct 06, 2017, 22:39:08 »
I took this last night whilst trying out my Polemaster.  I set up on the lawn as there is not enough space in the Obsy for the pier and the HEQ5 and I bought the adapter for the HEQ5 since this is what I use for camp.

I also wanted to try out the alignment and guiding so thought I may as well take an image while I was at it and all set up despite it being a Full Harvest Moon.  There are few targets I can do from Home these days, can hardly see anything except the major stars, could hardly see Cygnus or Cassiopaeia.  Has the LP just got worse or is it the LED lights I wonder?

Anyway, here it is.  At times there were a lot of passing clouds and I ended up throwing away almost as much data as I kept, so decided to reduce the Ha exposures to 5 mins as I was wasting too many subs.

HEQ5
WOZS71 & Atik460EX
Ha 10 x 10 + 7 x 5 (length reduced because of passing clouds wasting subs)
Oiii 8 x 300 binned
Sii 7 x 300 binned
Total 3 1/2 hours
Stacked in Astroart and processed with Registar and Photoshop

N.B. Image updated (originally processed on laptop with no gradient exterminator)

Pretty amazing from Bromley esp with full moon.. shows imaging can still be worthwhile from light polluted locations..

Better if you are pointing in opposite direction to the Moon i find.
But a  lot harder to find appropriate camera settings and length of sub , on same night i did 100 second subs at ISO 400 half normal, with mixed results, still trying to process.

Thanks John. 

Roger.  I would never attempt to do anything (apart from experiments) on a full Moon unless it was with narrowband.

You have got a worthy result, the gold wreath around the blue is very attractive and really picks out the heart shape. If you can do this ona full moon I wouldn't worry about the LP. How come only two colours from three filter bands?
Life is like a box of chocolates, scoff it while it's in front of you.

Thanks Duncan.  I guess the third colour is blended in somewhere.  I was surprised to get such a lot of blue as the oiii component looked very weak so not really understanding it myself.

Amazing Carole
I looked out and saw the full moon and went to bed...
Very impressive.
