Great Andromeda nebula

A combination of the image with the Vixen R200SS and the Takahashi Sky90. Only 2x seven lights were used. The different filters give interesting differences in the blue stars. The IDAS D2 filters more blue light. The two images can be found here

R200SS: https://astrob.in/kjpw87/0/

The two series of frames were calibrated and debayered with flats and bias images of each series. Then all 14 frames were drizzle integrated with a distortion correction, which was necessary at the corners. Drizzle integration brought better resolution than the two separet images. It was necessary to take care of the different orientations of the two series of images.

I hope you like it. Let me know what you think.

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.
