M1 in Ha/OIII 1/5/12


Recommended Posts

It was close because of the clouds but last night I finally managed to get some imaging in after nearly 6 weeks off.

Bagged 1 hour of Ha in 10min subs and 2 hours of OIII in 10min subs.

Atik 16ic mono/Astronomic filters/ED80 on HEQ5 Synscan Pro. Guided with PHD, QHY5 on Brightstar OAG.

Stacked in DSS. Processed in CS3, maybe a little too much.

Aiming for a couple more hours if the skies ever clear again.

I tried looking for M1 last night and couldn't find it, but the moon was really bright.

Nice picture by the way.

Great image Noel.

Just how do you get the clear skies to do 3 hours worth? I've been bosting to get some O111 data to add to my last years Ha and cant get 5 minutes of clear sky.

Good capture in tricky conditions and fine colour.

You've used a filter on it though (noel's actions?) which has caused artifacts.....what did the processing involve?

I reckon there's a fair bit more to be had out of what looks like good data :)

Yes, it was XiMagic's XiDenoiser plugged into CS3.

I added another 2 hours of Ha last night and have included it here.

False colour is a la Cannista Bicolour method.
