Jacoby 1 - PK085+52.1 (Uwe Deutermann)

Jacoby 1 - PK085+52.1

Revision title: Wide image crop

The Spring dilemma solution what I would call this trial on a difficult target. Everybody knows: Spring time is galaxy time, and usually I do have my "LRGB filter wheel" out at that time of the year. But summer targets are already visible in the early mornings, and for those some NB filters are required. Since I do not want to get up in the middle of the (every) night, I needed to find a target that would be worth doing with NB filters, and Jacoby 1 presented itself very quickly.
Knowing that this would be a difficult one I went right away with 10 minute exposures for the OIII channel, I tried out later 5 minute exposures just to see what they will show, and after looking at the images I was glad that I chose right from the get go the 10 minutes, made quite a difference.
The Ha channel provided an even fainter nebula, assuming that most of the SN remnants show up in OIII. Always nice as well to have some LRGB data of this area as well, makes processing of the stars easier. For those I chose for the very first time a gain of 0, wanted to see if this makes a difference. After processing them I am not sure if it did, they came out "usual", maybe I will need a different processing of the stars to really take advantage of this. I tried GHS first but gave up very quickly since the results were very discouraging, the stars looked awful. All hats off for Bruce's attempt on M13 with GHS!!
Interesting for me was that the galaxy right beside the bright star in Jacoby 1 was not plate solved, although many other fainter ones were.

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.
