My first attempt at running multiple subs on 2 imaging nights of data collecting. I will be gathering more data in a few days from IC 434. At my location I have a very large cedar in the south that is now keeping me from doing long imaging runs in a single night. I am good for possibly 40 minute runs per night.

I was very pleased at the data collected thus far using my IDAS-D1 filter with my Hyperstar III lens at F2 520mm from 27 2 minute unguided subs.

On he revised version I processed DBE in Pixinsight 1.8 to control the vignetting in the corners and create a more vivid color contrast .

Upon looking at he previous revised version I posted I noticed some concentric ring circles in the image probably from reflections off my Hypersar III Lens. I went ahead and corrected this by applying a flat field in DSS. I will need to register more flat fields in my files for next imaging runs

This is by far my best image I have ever captured to date from any DSO and I'm very pleased with the outcome.

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.
