Second image from my 6200MM. Gosh I love the FOV. Like I read from most of you, “wish I could capture more data”. Me too on this one, but clouds clouds clouds. California snowpack it at record levels though! I when up to the Sierra’s a week ago…unbelievable snow to see.

This is purely RGB with just a tad of Ha blended in but with no luminance. I’m very pleased with this rig as detail is phenomenal even from backyard (many PGC galaxies are resolved), stars are round to the corners and the FOV is nuts. The only thing I don’t like in the image is the blown out bright star Alnitak. Guess I needed shorter subs? That being said, I can still see several pinpoint stars in its glow. Alnitak shines ultra-violet light into the nebula causing electrons to be knocked away from the hydrogen gas clouds.

-john PS had to buy another slave 5T hard drive as the file sizes are also nuts.

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.
