Orion Nebula Messier42

This nebula is an absolute must in winter during sociable hours while you get away with short exposures and a high chance of success.

Rev B is just a warm-up picture, 37 x 60 sec.

Please have a look at the master flat in Rev C. Can anybody figure what these vertical and horizontal bars are? They can be cancelled away with flats though and I guess I know the perpetrator.

Hundreds of meteors which did not enter the atmosphere (Rev D) were flying through each of all frames in various directions (removed by stacking). I'd love to make a video but still looking for a FITS-to-PNG/TIF batch converter for my 180 lights (I won't do it manually). The PNG/TIF need to be stretched and saved with colors. ASIStudio's FITS viewer is of great help but cannot bulk convert except for unstretched monochrome TIFFs. Any pointer is welcome.

Has anybody noticed that SharpCap Pro when capturing flat and biases saves the first bias frame as a flat frame? Maybe intentionally, but probably no good when stacking in Siril, etc.

BTW, if you haven't done so yet, please get the latest version of SharpCap Pro which now includes its own plate solving algorithm and index files. It works like a love poem and is as fast as a young god. Also great for quick star hopping. EAA for busy people.

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.
