Melotte 15 in SHO - Heart of the heart

While trying to image with a second setup which was new to me, this setup to get subs for IC1805 or Mel15 was the one I thought works without problems. But I imaged the first time with temperatures below zero and there were a lot of problems I had to face. I never had those issues before (at least I never noticed them). The main problem was a really bad amount of flexure. It took me three days to realize, what the problem was. I tightend some screws and placed the guide scope at a different position on the tube of my newton. I took some more subs on the evening of the fourth night. But the clouds rolled in and I was not able to take more images. So I had to use what I got. While Ha was quite usable, the OIII and SII data had bad and elongated stars that create some weired halos in the direction of movement. So there is a lot of room to improve. However, I finally processed the image, because I really love the subject.

The day will come, when everything works as expected... I am quite sure.

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.
