LBN 623 The Ghost of Cassiopeia

Wow, what is this? That`s what I thought when I saw this nebula for the first time. Now I know, according to The Blues Brothers, this nebula has both: emission AND reflection. Though the blue reflection part is kind of weak and, to my great remorse, cannot be seen in my picture. If I used only my RGB footage, then yes, it clearly shows up. But introducing six hours of Ha kills the reflection part.
I had a hard time gathering good (clean) footage as well as editing it. I was after this DSO several nights, threw away a lot of frames because of high clouds and halos. What I present here is more ore less the essence of six nights Ha and RGB (mono) shooting with my ASI 2600 MMPro, the TSA 120 and Antlia filters.
Some facts about the DSO that I found @skyandtelescope.org: The ghost ist 550 lightyears away from earth - and is fed by the nearby (well, some lightyears away) blue supergiant star γ Cas. No wonder i had trouble controlling this star in the frame: it is 65.000 times brighter than our star, the sun. And 19 times more massive.
Though they call it The Ghost, I would rather consider it to look like a chicken, showing the middle fingers. Oh, I know, chicken do not have hands and middle fingers. That`s why I stay with the original naming.
Anyway - this is the real first light with my Takahashi TSA 120 which I was lucky to receive in December. Next target is probably going to be the Bubble Nebula.

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.
