Iris nebula NGC7023

After buying a used QHY 183c camera, I decided to use my 8 inch Newton to collect some data of the Iris nebula. Sadly, the telescope was heavily misaligned and my stars appered to be triangular. But for a first light of the new camera, I am really satisfied of how the camera worked with the Newton. The goal is to prepare a setup for the galaxy season and the smaller sensor helps with this. Otherwise I have to crop the images of my ASI294MM which uses nearly the same pixel size but offers a wider FOV. Because of the used Coma corrector I am slightly oversampled. But with the fast Newton this is not a great issue. Of course, I have to realign all mirrors in the Newton. So nothing special, but a starting point...

In comparison to all the other summer subjects which I usually do in narrow band, the Iris nebula is a true RGB target. It felt like it was a great subject to test the 183c. I really like the appearence of the backlit dust clouds. It looks very interesting to me. The diffraction spikes of the center star may not be very charming for everyone out there, but for me, it adds some interest to the final image.

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.
