Horsehead and Flame Nebulae - 8se and CEM120

Moving the guidescope to sit on top of the 8se (in other words, the same scope that is doing the actual imaging) helped get rid of most of the elongation due to differential flexure. I tightened some cables further as well. Huge thanks to the PHD2 community and CEM120 user group for all of the suggestions! This is the first time that I have been able to get usable 7 minute subs! (The image is a stack of 18 subs @ 4 minutes and 3 subs @ 7 minutes. Clouds rolled in an prevented more subs - they also contributed to some of the fuzziness. I tried to tune that out in processing.

There are a few of the typical lens flares associated with bright objects near the edge of the image - this has always been an issue with the Celestron f/6.3 reducer-corrector. Similarly, there are also some stretched stars in the corners. I know there are much better scopes for DSO imaing than the 8se + f/6.3 , but the 8se and 80ED are all that I have at the moment. Hoping to add a new scope to the family later this year...

Thanks for looking!

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.
