My first HA exposure, M16

Well, I had nothing but troubles last night trying to get a Tri-color Narrow Band image of M16. I had dirt on the CCD window that I had to clean, in the dark. I had to do two runs of Polar Alignment Correction to eliminate the drift and then fought flexure so that I could not get the 10 minute exposures that I wanted to use.
The next morning I realized that when I reinserted the camera, I did not get it fully seated in the focuser, causing the flexure.
Oh well, I ended up with 120 minute, 6 min x 20 subs of HA only. Here is the shot as it stands now, and I hope to add O-III and S-II at the next night out. Click on the image to get full resolution and size. Hope you like it, I took all night to get these few exposures. :S

Floyd,
The full resolution image looks good despite all of the difficulties I saw you work through last night. I think it was certainly worth the effort although it's a shame you encountered the problems that you did. I like the detail in the nebulosity that you captured. The Eagle looked pretty good with an 0111 filter in my scope last night as you may recall so at least the transparency cooperated so that's a plus along with your fine image!

Still, very nice image! Ah yes, the quirks of imaging. I get them all the time.

Ah,one of those nights huh
I think we have all had some of those!

Despite the problems you ended up with a very good looking image,I look forward to you adding the OIII&SII.

Nice work,


Jason

Floyd,

Welcome to the headaches of imaging! Some nights all works well, other times, well...

Anyways, you did a great job with what you have! Hope you grab the rest of your data! I'd love to see your version of the Hubble Pillars.

Looks great Floyd!
Lots of Nebulosity exposed! 8)

Very Impresive, You know it was not very long ago we could only see this in a hubble image now look what you have done. Amazing. . You should be very proud of your self..
Congrats!!
