Seems like the weather this summer is pretty bad for a lot of folks so far and here is no exception. I have a number of targets in various stages of planning and execution that are very slow to progress as a result, but this one comes closest to having enough data to at least see what it might eventually yield. After PI's SFS process, I am holding: 

 

R:  23x2minutes

G:  21x2minutes

B:  21x2minutes

 

AstroPhysics EDF 130mm f/6 with flattener, QHY268M with Optolong RGB filters, AM5N

NINA, PHD2, PixInsight with RCAstro X suite

 

So not a horrible result for a bit over 2 hours total imaging time for a target that doesn't get very high for me. Not sure how much more time I will devote to it because of its location. As a glutton for punishment, I have other low-hanging fruit targets I would like to pick up this summer as well, but my windows are closing quickly. Here's hoping the weather relents, for all of us. 

 

 

Edit:  after posting this, I spent a bit of time adding about an hour of dual band OSC data that I had saved from 2020.  With the result of very basic addition and little extra processing, I think I am moving on from M16. Of course it could use more time, but there are other targets beckoning and this one won't get a whole lot prettier even with double the time which I am not likely to get anyway!

Thanks, Gilmour, but it really doesn't do them justice, does it? A recent image with a C11 as I recall is really amazing. But with the altitude I get this at and the summer humidity haze, this is about the best I can hope for. 

 

But I did take one more crack at it and added an hour of Sii just to be all-inlcusive. Then I really threw everything in the blender and gave it whirl. The result is in the A-bin pile. Now I really am done!

Really nice details considering the limited integration time, Norm.  M16 is on my list to shoot once I get my M20 & NGC 6531 image finished.  Of course with the clouds and winds, that may be in 2027.
