Here's the inaugural image from my new Borg 107FL Petzval f/3.9 Astrograph. This scope sort of replaces my old Willliam Optics GT 102 APO, which I sold a couple years ago, only much faster at f/3.9 than the reduced 102 was at f/5.6. The FOV is quite similar to what can be achieved with the William Optics Star 71 f/4.9 Petzval and an ASI 1600MM, but there are significant gains in both image quality and speed with this system. Colleagues have been posting interesting color images of this area, so I thought to join the party. If skies cooperate I may be able to grab some SII data and produce a SHO rendition before galaxy season slams the door on us nebulae imagers.

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.
