The Deer Lick Group - NGC 7331 and its "Fleas"

I've wanted to image this target for the last few years but I never had a mount that tracked good enough to capture a target like this at f7. When I bought the iOptron CEM70 I knew I would be able to give this galaxy a shot. All seemed to go well and I'm excited to try my Edge HD 11 at f10 for the first time.

I started shooting this target bin 1 mode with my ASI2600mc pro and then switched to 2X2 mode. The seeing conditions in the Midwest are usually average to below average and I realized that I probably would not see any difference in resolution between bin 1 or bin 2 mode. When I looked at both sets of calibrated and stacked images, I was correct in that there was really no noticeable difference in the resolution of the final images.

The other thing I did with this image for the first time was dither and WOW! I can't believe how much of an improvement it made with the image noise. The dither set-up was fairly easy in SharpCap and I can't believe I didn't attempt this previously. Using an OAG the image scale for both the guider and scope were the same which made the set-up for the first time easy. Moving forward, I will be dithering all the time.

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.
