M27 - One of my favorites

M27, the Dumbbell Nebula, is one of my favorite planetary nebulas. Love the shape and wispiness of the gas clouds along with the associated colors from the various elements. I shot this about a year ago with my Lunt LS80MT. This was with my Vixen ED103S setup. I'm coming along with Vixen. There are a few more minor issues to deal with. I have a flattener on order, which is needed. I had to crop the corners off of this image because of the "egging" of the stars in the corners. The flattener should remove or come close to removing that. I need to do some fine tweaking of the optical path as analysis with PI and CCD inspector both show some tilt issues but I don't wish to go after those until I install the flattener and see what I can do to eliminate the bad deformation in the corners.

Just a slight tinge I notice of red in the background. I can probably get rid of that with some more judicious use of masks and some color suppression in Photoshop. I will look into that. Finding out a lot of valuable things I can do to center on that last 5%-10% of polishing, which usually ends up being 80% of the effort. All a process.

Enjoy!

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.
