IC1396 Elephant's Trunk in HaHSO

Finally first light with my ASI2600MM Pro! This is second light with my RC10 as well.

This combination used Ha for Luminance, Ha for red, Sii for green, and Oiii for blue. I tried several combinations including some fancy Hubble-palette-like ones I've used in the past, but I don't really have enough signal in Sii or Oiii for that yet. Unfortunately a lot of my Sii subs were lost to clouds.

I would like to get much more data than this, especially in Oiii and Sii, but it's all I've managed so far. The weather has been terrible for the past two months, unusual for our summers which are usually hot and dry. I took advantage of the one (mostly) clear night in a month. Clouds delayed the start to my imaging, and they briefly re-appeared around 4am.

I'm troubleshooting an issue with RA guiding drifting over time, so don't squint too hard at my stars. They're ovals. It's odd. Overall average guiding is great, about 0.5" to 0.7", but over the course of time (including over 300-second exposures) guiding just drifts. I have to frame my images to ensure my target doesn't wander off.

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.
