M42 Orion Nebula on a clear night

In December I had a go at M42 (posted here) but the sky was rather hazy with flickering stars and unclear Milky Way. Night before yesterday I finally had another chance, with a considerably clearer sky. What a difference that made to sharpness and star size!

Sadly I spent days trying to improve the old one while clouds or moon were in the way of more data (but I guess I learned a bit more about processing). In any case, I am quite satisfied with the M42 data I have now and will go for new targets next time it clears up. Taken with an Explore Scientific ED127 with 0.79 x TS Photoline reducer and a Canon 60Da at ISO 1600. 25 x 3 min (plus 10 x 15s and 10 x 5 s to save the core). No darks (it was -14 °C so a frosty camera with very little noise). On a NEQ6 with finderguider.

While I wait for more clear nights I am sure I will have a few more attempts at processing it and also do the Rosette Nebula I caught the same night.

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.
