IC1396, Sh2-129 and Alderamin in Ha.

My first Ha with Canon 600D microlenses less, Samyang 135 mm, 1st stop on EQ6R with Lacerta Autoguiduing thru guide scope 50mm.

600s x 16. I had issue with the false battery and so switch back to orginal one. Unfotunately, it was not charged enough and while the mount rotated the all night, the 600D got only 15 pictures, the 16th one was a versification I did before.

This first version is dof less.

First image stacked and processed with Pix. Use and abused maybe of the Starnet process to process separately the background and nebulae and reducing the stars on another hand. Gimp was very help full to get a thershold mask and play with curves.

Description: Still only light but stacked with Sirilic that enable stacking with debayerized APN while the script WeightedBatchProcessing from Pixinsight doesn't enable it.
I was not ble to get a contrasted result close to the initial one with new processing in Pixinsight. Anyway I've found the background better (due to better stacking) and so used layer mask to merge both under Gimp. Also I almost get rid of the halo around Alderamin.

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.
