LBN743, LBN762, LDN1457 & MBM13 in Aries

[gorann]

This spoky mix of faint bright and dark nebulae lies west of M45 in Aries. The bright blue star to the upper right is Epsilon Arietis, which at a distance of 330 ly is visible to the naked-eye. LBN762, LBN753, and LBN743 (from Lynds' Catalogues) form the major horizontal structures across the image and are about 1000 ly away. The rather bright nebulosity annotated as LBN762 in the upper left is part of the larger collection of structures seen there catalogued by Magnani, Blitz and Mundy as MBM13.

I have found very few images of most of the nebulosity seen in the image, and even fewer good ones, but a prominent exception is the APOD by Rogelio Bernal Andreo: https://apod.nasa.gov/apod/ap171209.html

This is a two-panel mosiac captured over two nights (6-7 Jan 2022) with my dual-RASA rig. So RASA 8 with ASI2600MC on Mesu200, no filter, 285 x 4 min, so 19 hours. Processed in PI and PS.

Cheers & CS, Göran

Superb capture Gorann, I dare say for me to have a go at this at F7 I would need a couple of days of data.

Loving all these creepy dark nebulae you have been posting,.

Beautiful - I wonder what a starless (or perhaps star-reduced) version of that would look like!

Thanks a lot Alan! Yes, I would not aim a f/7 scope at this unless I was on a Chilean mountaintop with continuously clear skies😉

Thanks a lot! I am not a big fan of starless images but when I process these faint nebula images I initially make a starless version to stretch the nebulosity before bringing the stars back. However, you made me wonder what it would look like if I remove them at this final stage. So I run Star Xterminator on the final image and it looks like this. I brought the big stars back as removing them creates too much artifacts:

I've not found any obvious animals/characters yet 

Very nicely done.  Quite a natural feel.  Edit - how early in your processing do you apply Starxterminator?  I try to stretch at 32 bits but star removal only works on 16...

If you chop that into 2 or 3 vertical panels, that would make a nice diptych or triptych - Nature is an abstract painter!

Thanks! I do all my stretching in PS so 16 bit. I apply Star Xterminator after I start to se the first signs of nebulosity.

PS. Up to the left (MBM13) I see most of the Adam's Family.....

Great image...I doooo love these dark, nebulous captures. The subtle colours are just perfect.
