Jellyfish under a full moon

[vdb]

So against better judgement I went out last night and took

4*1800 sec Ha 7nm with fsq-85 and H35 camera.

very nice and super long subs!!

Thanks, the long subs is something I've been working towards, I aligned the polarscope of the IEQ45, and guiding was running between 0.1 and 0.15 rms ...

The 2 hours showed 0.00 degrees rotation during stacking in DSS, so I'm happy. (no drift align, just polarscope ...)

That's a great image - really shows why they call it the Jellyfish!

That is superb!!! I didn't think conditions last night were the best for imaging, but you've done a great job! /bigthumbsup

Looks like good judgement to me! Nice details and good signal in the fainter area at the top.

Nice Jelly. Long subs in Ha really pay off. The difference between 1800 secs and 3600 is amazing too on the really faint stuff.

Cheers

1800 second subs?

That's not a typo... that's 30 minutes?

Impressed.

How did you prevent over exposing the frames with a almost full moon in the sky?

Ye no typo ... 1800 sec per sub ...

Ha 7nm ... the reflected moon light "has very few" red due to Rayleigh scattered light phenomena
