SH2-275 Rosetta Nebula

Revision title: 3 tile Casper

I Finally managed to get time on the Rosetta Nebula last weekend after 5 months of bad weather. Properly testing out my new camera I am very impressed with this OSC and how well it did on this image in such a "short" amount of time.

I had two really perfectly cold and moonless nights, after freezing my *@# off setting up the rig in -11c temperatures, I am happy that I have the asiair, eaf, and the possibility to control everything from the warmth of my house after the initial setup. The second night was easier as i only had to attach the telescope to the mount and with just a slight modification to the polar alignment i could get back inside quicker. As for the picture I'm very happy with the outcome, I used all calibration frame types except dark flats but to be honest I dont think I needed them anyway. Still the perfectionist in me doesnt like the way the stars turned out and possibly should have checked more than just one preview screen while sharpening, also the picture is not deconvoluted because I was getting strange blobs of colour that I couldnt correct with deringing or denoise, lessons learned for next time and more work to put in, but otherwise totally happy, and think for an OSC its the best picture to date.

Hope you Enjoy!

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.
