Pickering's Triangle

This is one of a few test images with my new to me Orion MN190. Fixing the scope up with cooling, a better focuser and sturdier rings it is now ready to spen more precious time under the stars.

I found however that the stars with this scope are more bloated than I would like, and significantly worse than an APO with a similar FOV. Thus it was an opportunity to try some new star reduction techniques. I am not entirely satisfied with the result but a combination of Adam Block's star de-emphasis process, and a starnet mask with histogram adjustment, I managed to reduce the stars without using any erosion and I think that keeps them looking somewhat natural, if not a bit too dim.

This seems like an ideal opportunity for a mosaic, however I will likely wait for this part of the sky to come back around again next year to begin.

This is a true HOO process of this particular area of the Veil Nebula / Cygnus Loop.

Note: This image is unguided, unintentionally. I recently upgraded my imaging train with a dovetail delete for the QHY 294, which drastically reduces backfocus. Couldn't quite reach focus on the OAG. Now solved with more spacers and longer through bolts.

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.
