Initial Posting
I am unlikely to finish a color version of this target, so I am posting the Ha stack as a mono image. This target was the first I shot testing the OAG. I still have to dial it in, but the results are acceptable I think. The FWHM of the unprocessed stack in 2.57..almost decent. Seeing was not very good, so I am not sure how much better I could have gotten it. I should be able to guide with rms errors better than 0.7-8. I should be able to get in the .3-.4 range. I wanted to shoot this target in LRGB, but the Moon prevented that. Having real trouble getting Maxim DL to calibrate and guide. PHD2 is more able for some reason. Can't dither using Maxim and PHD2--so must eventually switch to Nina.

Additional Posting
Just for kicks I added 3 hours of OIII and 5 hours of SII data from the TOA130 dataset. I am unlikely to want to complete this target again in the Hubble Palette, and bicolor never comes out very well. I will probably use this target to fine tune the OAG and get Maxim to guide/calibrate. Other atrgets are calling

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.
