Imaging options with Mr. Moon in the way

Posted By Jim Thommes
Alec,
Well here is what I do....

1. Ha works great on the right objects in light pollution or a bright moon - the right objects usually imply wider fields.

2. I stay at home for imaging - no point in traveling to the dark site.

3. I have usually limited myself to brighter objects with the moon out (Globular / Open Clusters, bright planitaries). And if you want to make lemonade when life gives you lemons, you can turn your camera on the moon (get the neutral density filters ut though).

4. Stay inside and process the data you have already collected during a favorable moon.

Sharpless 2-86

Nice image Dennis!

Good technique and recovery given the forced change of plans. Other than the image scale and undersampling, you can't tell any negative impact from the limited data.

M68 Globular Cluster

Posted By Jim Thommes
Ivan, Larry,

Thanks for the comments...

Ivan, I like my Artemis a lot - it is pretty much a "no frills" camera. I almost always need to travel to dark sites, so I tend to favor the simple and rugged. In the case of the Artemis, noise and quality are quite good as well. I guess the Artemis is now only available from ATIK as a completed camera - No more Artemis "Kits".

M27's lion's mane

Tom,
Nice deep image - congrats! Of course for this data you probably didn't care too much about the full moon smile

How many subs in the 90 minutes?

M57 with ST-7E and Meade RGB

Posted By Jim Thommes
Nice Image Eric.

Ty is right, M57 can be a challenge. It does look like the star colors seem to be biased a bit toward Magenta. I don't know if mixing up green and blue produces that result though.

Crescent in Ha

Brian,
Congrats on first light with the set up. Pretty good pic out of the chute.

NGC7000 - The Gulf Region in Ha

Posted By Jim Thommes
Tyler,
Nice image. I too recently imaged through some smoky skies. As long as it's not too thick, Ha seems to come through relatively well.

I like the detail and sharpness you got on this image.

NGC 6357 - Emission Nebula

Posted By Jim Thommes
Thanks to all for your comments..

I wasn't 100% pleased with the processing on the original so I had another go at it. (attached).
