Description
We are back to deep sky imaging after a long break. Spent a significant amount of time aligning the tilted CCD, but I think it can be further improved. I am satisfied with the results considering how long it's been since I have processed any deep sky data. This is an HDR image of 5, 15, and 30 second exposures in order to bring out the Trapezium and the surrounding nebula.
