M27 - June 28, 2009

I like it!

Well done. The background could use a bit of neutralising (it's very red) but the object itself is great.

Thanks guys!

I tend to have issues with backgrounds. I am either too this or too that. I was trying to avoid the usual, "too green!" comments.

Hey it worked!

Aside from the color balance issue it looks great Mark. Nice tight stars and focus looks dead on.

Take a look at this image along side yours with the histogram window open in PS. Note the channel spikes are more in alignment(I did a very quick adjustment). A sample of the background should show close to R=25, G=25 and B=25.

Thanks for the tip Steve.

I will re-process it over the next few days and see what I can do about that.

I am back in the game. I should be doing more over the summer.

Very nice work. Now, I need to finish up my telescope project so I can start imaging.

OK, I reprocessed it from the raw frames. Also after re-reading the image posing guidelines I see I am permitted to post a larger version.

Nice processing the second time around and a great capture. good star shape corner to corner. I personally would back off the blacks a tad, looks a little too black now.

Alot better and very nice capture . I don't know if it's my monitor or what but i still see a purple outline around the brighter stars . Being an AP Scope this cannot be CA so must be something due to processing or something with my monitor .

It's the processing.

I tend to have a heavy hand with this aspect of the hobby. Like a bull in a china shop! lol

If only I had unlimited time to learn and to practice.

I appreciate your critique and tips guys!

Did you fix it ?? I'm at work on a different computer and it looks even better now ! Not the purple i seen before . Better !! One thing i like about the M27 than the M57 is M27 is in a denser star area than M57 is . Great shot !

Must be your monitor. I didn't touch it since I posted it.

If you fancy turning Image Editing OK on under your profile we could perhaps show you the results of some further stretching...there is a lot more data in there yet . There is a bit of purple fringing though. The background however is gloriously uniform, you must have fantastic skies

Chris,

If you want I could send you the tiff file. It's still 16bit so it's about 87 megs.

I could just send you a link so you can download it if you wish.

In the meantime I will turn on Image Editing OK.
