M 82 Cigar Galaxy

Messier 82 is a very active starburst galaxy not so far away. I had hoped to image the gas leaking out of M82, but for this goal my total integration time is too low.

Well, i had several problems the evening i took this image: First, guiding did not work anymore after the meridian passthrough. I dont know what happened, but i could not get it started again. I had imaged more than 3 hours before with exceptional guiding, so i was okay with it. But the next day i saw that all images where out of focus. You can see it at the spikes of the topleft bright star when zooming in. I don't know how this could have happened, because since i started using a bahtinov mask i had never ever problems in holding focus the whole night. The only thing i can imagine is that the focuser moved a bit after i focused with the bahtinov - or i had a "Knick in der Optik" while using the bahtinov mask like a german saying says...

So i think the result is fairly okay regarding the problems i had.

[Edit]: Ah, and there is no annyoing noise-blob like in my last pictures. So maybe it was the moon or the reducer or a combination of both, i think.

And the image was taken after the party of my fathers 70th birthday. Gratulations again :-)

[Edit2]: I totally reprocessed the image without bias and with new darks. I am not sure if this new version is an improvement, but without any doubt it helps to understand what i am doing in PI :-)

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.
