Lovely image of one of my favorite warblers, Cal. Been missing your images.

This is a truly terrible picture but I thought I'd post it anyway to see if anyone can identify the bird. I photographed it near Austin, TX last month.
I'm thinking it might be a scarlet tanager, but it doesn't look like the others I've seen before. It was a fairly large bird, even for a tanager.
I had to shoot it through glass and in low light so the image is really bad. -Kurt Horsley

That's a Summer Tanager molting into it's summer/adult plumage.

Combining Two Night's Data?

Posted By Jeff Hapeman

Larry Durst said:

Hi All,
I plan to add more data tonight for an M100 I shot the other day--just feel I need more on my lum. Question: how should I add the data? (I use AstroArt3.) In other words, if I align the two different nights separately to create two different masters, then combine those two masters together, is it the same as if I did one big stack of the individual frames? The former would be my choice since it makes aligning much easier (I'm shooting 30 second unguided, so it's a lot of subimages!) Also, if I were to make two masters, would adding be preferable to averaging the two together? Or is averaging okay, too?
Thanks in advance for any advice,
Larry

I am not sure how AstroArt combines, but adding all the subs using a statistical-combine method like the Sigma-Reject or SD Mask method will result in lower total noise.

Have fun!

Quite nice, Vince, however, it looks like you have clipped the histogram on the black side, which makes the sky a little unnaturally black, and may cause you to lose some of the faintest regions of the galaxy. That is easily fixed though--the rest of the image is perfect--guiding, focus, etc.

this might go under insects,but, I know more of u look in here. This was made last fall. Anybody have a guess at what may be inside ? almost 3 inches tip to tip in the door jamb?
Should I be afraid, or very afraid ? lol

That looks to the be cocoon of a Cecropia Moth, or one of its relatives. Should hatch very soon. Very impressive large moth.

Early morning visitors

While stumbling to the kitchen to grab some much needed coffee something caught my attention out of the corner of my eye...

Realizing what it was, forgot the coffee and grabbed my camera!

Cropped, resized and optimized only. (Not sure what size images we could attach, or how many.)

Did you offer them some coffee? Nice early morning sighting! Yesterday morning we had a male turkey in our yard, but he ran off before I could get the camera.
