LDN 1235 The Dark Shark's Head

I proudly present my first dark nebula and my longest single night exposure, ever.

The nights started very clear and not to cold and ther was no bigger temperature drop expected. The moon was out this night but I didn't care to much. This should be the night for my fist dark nebula and I was aware that they need some extra time. "No problem, the next night should be clear, too. So I can put a few more hours on top", I thought.

I am still a lerner on this hobby and I've learned two things that night:

1. Framing and centering of an object should be well prepared. Usually I do that with some test images, where I can see the object (or parts) and do it "live". This time it went out more complicated, so I decidet to go by coordinates and plate solving.

Unfortunately Dithering and struggeling with PHD2-Calibration together with my small FOV is not a good combination. So the image ran a few arc secs out of my planned center.

2. Don't plan with the weather(forecast). The next night was cloudy....

Anyhow, I am more than pleased with the result even if it will not win any competition.

I have my first dark shark (I was planning for this more than a year) and I have learned a lot of things catching it.

Hope you enjoy it, too!

Mike

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.
