Barnard 33 System DSLR HAlpha - during a full moon

[MarsG76]

Greetings Astronomers,

The work on imaging my next object has begun, and as always and common to us all, I have to juggle imaging between clouds and moon phases.

This is 3 hours of halpha data of 900s and 500s subs captured the night before full moon and on the full moon night through a 7nm Baader Halpha filter using a modded Canon 40D DSLR. I'm hoping to spend a night imaging 30 minute subs (when the moon shrinks to last quarter or smaller) to try to capture some of the dimmest nebulosity as well as spend perhaps another night imaging 15 minute subs through a Baader 7nm OIII filter to see what difference adding OIII signal to the final color image will make.

Before the moon was first quarter I've acquired 3 hours of usable RGB data across 2 mornings of 300 second subs. After stacking I realized that I need more RGB subs for enough SNR to stretch the data, so my plan is to perhaps spend another night of exposing 300 second subs but through a unmodded DSLR, once complete, I'll stack and process the RGB frames and add the narrowband data to it for a full color image.

Sorry for the drawn out ramble...

clear skies,

I'll start a new thread when finished... The earliest I can hope for finishing it is during the next weekend, if not within a fortnight then it migh have to wait a month... But being near summer here, I'm confident that next weekend might be ok.
