Title: North America & Pelican Nebulae
Post by: Carole on Mar 28, 2020, 22:44:26
Had to start imaging at 1.30 am on two nights to get this by the time it rose above the house getting to bed after 4.30 am.   :!

A lot of cloud spoiled the subs on the 2nd night when I got the colour.

Samyang 135mm F2.8
Atik 460EX
HEQ5
Ha 16 x 600
Oiii 2 x 300 binned x 2 (clouds spoiled the other 6)
Sii 6x 300 binned x 2
RGB for stars 8 at 150 each
Total imaging time 4 hours 20mins

Thank you Noel.  When you say you like the stars, do you mean the RGB?

Thanks Duncan, really glad to have discovered this lens.  I will probably crop the top out at some point, but wanted to show the full frame for star shape in corners feedback.

Yes exactly; I like the colours but looking at the Ha - the stars are nearly perfect right out to the corners, which is really good.  Just goes to show what your lens is doing.

Thanks Noel, I have started trying to add RGB stars now to narrowband images, though it has taken me a while to find a decent way to process this.

Thanks Mark, yes I am really pleased with this lens after years of saying I am rubbish with camera lens imaging.

In this instance it wasn't a case of the workman blaming his tools, it was the imager blaming herself when it was the tools that were at fault.  Lol.
