100h Epsilon the second / LBN331, W63, StDr139, NGC6884, PM1-320 and many more LBN'S

Hey boys and girls,
In April of this year Frank and I decided to do a project together again. We had set the time again from August to October, as experience shows that the weather conditions here in Germany are stable.
So I had enough time to get my equipment ready to go again after electronic problems.
Originally we wanted to tackle the project as a group of three.
Matthias came over.
In June we started planning the choice of object and the image section. The choice went to the LBN331 in the Swan. In order to be able to expose our selected image section, Matthias had to make a triple mosaic for SII.
I had to make a double mosaic for OIII.
We will start the project in August.
Target - again 100hrs exposure time.
Unfortunately, Matthias dropped out because given the conditions, it was not possible for him to get the planned exposure time together for a triple mosaic.
Next time we'll do it differently! And then three of us 🙂Now there were two of us again.
Luckily the Frank had enough CS to expose Ha, SII and RGB for the stars. Luckily for me it also worked with the clear nights to get enough exposure time per panel.
So we actually got over 100hrs exposure time again for the second time.
The images with this amount of exposure time are amazing!
Only my OIII data was very tricky. Firstly because the signal in OIII is so weak and secondly because there was a difference in brightness in the background per panel. After many attempts it finally worked.
When editing the image, I decided on the HSO variant. And it should be bright in color 😜🤩
Something else.
But it definitely doesn't suit everyone's taste.
I like it though 😍
In fact, almost nothing went wrong with this second project. Cameras remained intact and the electronic ghosts stayed away too😃 Only a few clouds disturbed us every now and then.
It was a lot of fun again and the next project with Frank will definitely come 😁 Next time it will be a complete threesome with Matthias!!!

A little fun fact. That was the first light for my new Atik 16200M. 🙃

In the technical card I could only store the information of the exposures I made.

Object description

LBN331

The emission nebula LBN 331 can be seen at the top left of the image. This emission nebula lies in a dense star region of the Milky Way.
The field is also well represented in the DWB catalog and the lighter filaments of LBN 331 also carry the DWB designations DWB 179, 178, 177.
The bright central star in LBN331 is 32 Cygni.
32 Cygni is a binary star system (32 Cygni A and B). The orbital plane of the two stars is almost in line with the line of sight to Earth. This alignment causes it to be an eclipsing variable star system.
It is called V1488 Cyg.

StDr139 and NGC6884

StDr139 is a newly discovered and confirmed but still unknown planetary nebula in the constellation Cygnus.
The PN StDr139 is located an estimated 4000 light-years from Earth and shines very, very faintly in OIII!
There is absolutely nothing to be seen of him in a 10 minute recording. So it's no wonder he remained undiscovered for so long. In October 2021 it was finally discovered using digital sky surveys by the German-French discovery team Marcel Drechsler and
Xavier Strottner (StDr139).
Nearby is PN NGC6884.
The object was discovered in 1883 by E. Pickering using a spectrograph.
The astronomer Copeland discovered the PN independently of Pickering 1 1/2 years later, which is why there is a second NGC for the nebula - number 6766.
The PN is about 6000 miles away from us.The gas envelope is expanding at 23 km/s and was ejected from the central star a good 700 years ago.

W63 SNR

Super Nova Remnant (SNR) G82.2+5.3 (also referred to as W63) appears to be exclusively in the OIII emission line.
This SNR requires a very long total exposure time to elicit a visible signal.
In a 10 minute recording there is little to no visible evidence of SNR. The structure consists of thin, sharply demarcated filaments that form a vaguely oval shell. The distance is estimated at 10,500 light years and the age is between 14,000 and 21,000 years.

PM1-320

PN PM 1-320 is a small planetary nebula in the constellation Cygnus that exhibits extensive features in OIII.
The Propeller Nebula (DWB 111) is very close to PM1-320.
It was discovered by Andrea Preite-Martinez in the 1980s.

We hope you like our renewed collaboration 😃
We wish you all clear nights
Flo and Frank

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.
