Mandel-Wilson 3: Volcano nebula - northern part

This is the first light with my second RASA 8 and it could have gone better. I realized too late that both collimation and camera distance were off so I first regarded this data to be crap, and focused my attention at the data I had from my other RASA the same night. This morning I had another look at it and decided to try to save it by some radical processing treatment of the stars. It is still not an image to pixel-peep, especially in the corners. However, it contains some nice Integrated Flux Nebulosity (IFN) and I am glad I gave it a chance.

About a week ago I imaged the central part of the Volcano Nebula near M81 and M82. The part shown here is just outside and to the north of that image-field. It contains plenty of both reddish and gray IFN, similar to the IFN I imaged with my other RASA the same night (posted yesterday). That one was from the southernmost part of the Volcano Nebula.

Interestingly, also like in the previous image the reddish IFN does not show much structure while the grayish IFN is quite filamentous. Obviously they are two different things.

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.
