IC1318 Nebulosity around Sadr in Cygnus

Moon is up and I had two clear nights (with a rainy day in between) so I have been shooting Ha with my Esprit 150 and ASI1600MMpro (on Mesu 200). This was the first try of the TS 3" 0.79x reducer/flattner on the Esprit 150 and I am pleased how well the reducer worked, at least for the ASI1600 image chip. So here is a two panel mosaic finished off last night. 18 x 15 min on the right side and 20 x 15 min on the left side, with a large overlap in the centre to give more data to the details there (all at gain 139, offset 50 and -20°C).

The nebulosity surrounding Sadr (gamma cygni - the central star in Cygnus and the big one to the right in the image) is vaste so this mosaic could be expanded but I think my next plan for the object is to collect RGB with my ASI071 to make a HaRGB image.

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.
