IC1805 Ha

Another Ha image of IC1805. I thought it would be nice to share a partial work while working on a bigger project. I had a couple of clear nights and got a chance to test my new rig with different settings. The result presented here is an integration of 80 subs with attention to FHWM values. Surprisingly, there was not much of a difference in the resolution between integrations of 30 and 80 subs, at least not as much as I expected, however the noise droped down to some degree and the final result looked a bit more clear.

Description: I created this pano of four Ha pictures showing the same object to illustrate the visual difference between exposures. The top left was integrated from 140 subs 120 seconds 0 gain. Top right was created from 30 subs 240 seconds gain 200. The bottom left panel shows 80 frames integration of 240 seconds gain 200 subs. And the bottom right image was integrated from 220 subs, a combination of 140 frames 120 seconds 0 gain and 80 frames 240 seconds 200 gain. The bottom right picture shows superior eccentricity and lower noise in comparison to the bottom left.

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.
