IC1396 - The Elephant Trunk Nebula

My longest integration yet. Gem28, ASIair Pro and ASI533MC Pro ran all night, doing the meridian flip, continue guiding and shooting. It is really a game changer when everything can be automated.

As usual, seeing was not good, but luckily my image scale is rather large at 2.6"/px, so it works relatively well still. Only had 2 bad frames out of a 100 in terms of guiding and then had to discard a number due to satellites and planes and then a few at the end of the run, when the target was close to the horizon.

I think this must be my best astrophoto yet!

Original upload:
Processed in my 'usual' way with DSS and PS using Starnet++ to enable seperate processing of stars and Nebula. I was unable to get any other colours than red to appear. But I was still quite happy with the details.

Version B:
My first experiments using Pixinsight for the pre-proccesing, stacking, chanel combination and initial stretch. I still went into photoshop to do some manual cleanup of the starless image before recombining with the stars and finishing touches in PI. I am amazed at the vararity of colours that I get from the PI pre-proccesing! I can definately see why people use it.

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.
