NGC925 from the suburbs

Acquisition type: Lucky imaging

This is a combination of data taken over a couple of nights late in the year before the rains descended upon us. One night of data was 6 x 8 minute live stacks of 320 x 1.5 second subs with an IDAS filter and the other night was 4 x 8 minute live stacks of 240 x 2 second subs with an IR/UV Cut filter. I stacked the two sets of images, preprocessed them for noise and then blended the two images together before doing final processing. The total exposure time is therefore 80 minutes.

The outer regions are faint making them difficult to capture from the suburbs, but the internal structure of the brighter regions showed themselves fairly well. plenty of HII regions intermixed wit dust can be seen, along with numerous O-B associations.

I'll probably get a chance again sometime next fall to get more data on nights with good seeing to improve the results here. Maybe sooner if I can get to a dark sky site in the next couple of months with good seeing and a western view. My western view from home is completely blocked. However, the eastern part of my sky is the darkest, so imaging west of the meridian would not produce as good a result.

Description: I noticed I accidentally set the sky black point a little darker than I had intended, so have corrected it here. I think its an improvement? A little more of the galaxy's edge is apparent.

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.
