M42 the Great Nebula in Orion

As any astronomer can attest, once you get a new telescope or a piece of gear, the weather must oblige with at least three months of foul weather. I got a SkyWatcher ED80 for Christmas, and last night (3/4/18) was the first time I've been able to put it to use on a DSO. I've been waiting for this opportunity for quite some time. My previous attempt at M42 was with an 8" SCT, and I wasn't able to piece together the mosaic, mainly due to lack of good skies. So it was nice to be able to grab it all in one go.

This is a composite of 10-, 30-, and 300-second frame stacks at ISO800 and 1600. I'm still not satisfied with the stars, especially the large ones with purple halos (my DSLR is to blame), but it's something to work on down the road.

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.
