My new website

Tyler,
Nice site, very navigable - nice presentation.

It might be nice help out your frequent visitors. If you put a date on your main page or add a recent images page, or something to that effect, that will let us know if there is any new material when we cruise over to your site.

Cocoon

David,
Looks good! It also looks like you got some of the more subtle blue reflection elements of this object.
I like your camera wink

I use an Artemis with I believe is pretty similar. Manually guiding huh - I'll bet that takes some patience.

NGC 891

David,
Another nice image - congrats!

I am wondering if the blue green bias is more than I would expect for this object.

SH2-157 - One of those Dim Sharpless

Posted By Jim Thommes

Thanks everyone for your comments.

Eric,
I didn't know that there was a common name for this object. "Squid" seems like an apt name though.

Tom,
It was an interesting region for me in that I think it was the first time I have an image that has a border between two constellations go through it - Cepheus and Cassiopeia.

Double Cluster

Posted By Jim Thommes

Thanks everyone for your comments on the Double Cluster image.

Larry,
So one of the things I think helps with star colors is to take shorter RGB exposures - particularly for those of us with anti-blooming CCDs. Bright stars whose color data is at the top of the dynamic range tend to come out white. Shorter RGBs lower the ADUs on the bright stars and lets the color come through. Of course, then its hard to get the low surface brightness colors in nebulas. So its a bit of a balancing act with nebulas and galaxies, but with star clusters youa can go hog wild and shorten those RGBs.

My 2 cents worth.
