The Iris Nebula & One or Two Satellite Trails


Recommended Posts

This data set has been sitting on my hard drive since last summer, waiting for the right moment... well that moment finally arrived. Here is my image of The Iris Nebula (NGC 7023):

While gathering the data I noticed that loads of subs were photo-bombed by space hardware. I thought it would be interesting to do a stack that didn't remove any of the trails and here is the result. Yikes! I haven't counted how many there are, but it seems to be hundreds...

The image comprises 3 hours in each of R, G & B, along with 13 hours of Luminance. A total integration time of 21 hours.

Kit used: Esprit100 and QSI-683-WSG8 with Astrodon 31mm filters, all on a Mesu-200.

Processed in APP and PS.

Thank goodness for the sigma rejection algorithm when stacking!!!

 

Clear skies all!

Maybe the Iris nebula is like the place in the sea where all the rubbish collects! It's unbelievable the amount of space junk.
