Description

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.
