M 82 with deep H alpha

This is a combination of older and new data. H alpha and colors I took last year with my newtonian CT 10. So only new luminance data was necessary, which I took over two nights, when this galaxy stood in my quite dark northwest sky. It was necessary to blend out the totally burned out core of the galaxy in the pushed h alpha image. The combination of course was a little tricky and I managed this in PS CR 2 with layer masks. So I hope I finished a quite natural looking deep M 82 with deep h alpha information. When you look closer, you can see even a h alpha field on the top of the pic. I remember that I was astonished about that during livestack when imaging h alpha last year, but after investigating this, I found out that it is real. Luminance subs were taken with my edge 11 HD with CCD/ CLS filter. The spikes come from my cable holder cross for hyperstar in my dew cap.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
