Nice framing Olly and thanks for following my suggestion of a second panel😃 Now you just have to add one more to the right to get a very pretty galaxy in there: https://www.astrobin.com/lnhy4h/

Maybe not the most striking target but a very rare one well worth being imaged! The very few images I could find of it is clearly not of this class.

Clearly the camera works but there is a striking amount of hot pixels. What brand of IMX571 camera is it and what was the sensor temperature? My ASI2600MC (got three) and Omegon vetec 571C appear to have considerably less hot pixels (at -10°C).

I see. Mine is PS 2021. Hopefully Russ will update the action.

Yes, outstanding Dave! So many great objects compete for attention in that image. PS. Like before I do wonder what even more star suppression would make of it😉

You can also just follow the instruction made by the Russ Croman, the creator of Star XTerminatror: https://www.rc-astro.com/starxterminator-usage-notes/ I use the Photoshop action he gives out (click one "here" at the end of his instruction). In one step it creates three layers: Background, Starless and Stars. I use that action rather than doing it "manually".

A great overview of this fabulous region Dave! I thought the Rotting Fish was called the Guppy Nebula but now I am not sure, could be a name I made up myself when I imaged it. CS, Göran

Great image Peter! I love these objects with the nice contrast between the whitish "Gecko nebula" and the strong Ha in Sh2-126.

Yes, more evidence for the dust-sucking capacity of the RASA! Maybe add a frame on top to include LDN1082 (Barnard 150), which looks great in a RASA RGB image.

If you used StarXT it could possibly explain it.

That is an exceptionally nice and dusty rendition of this extraordinary area Olly! RASA rules!

If you are interested Olly you could make a try of combining the images. Not sure how good they overlap. Here is a tif of my final version. 20230312 NGC7129 RASA1+2 PS27(nebula tamed by curve).tif

Oh yes, it is amazing what you can do with the data once you get rid of the stars Olly! I imaged the same area with my RASA8 rig a few month ago, but it was full moon so I used NBZ filter for Ha and Oiii. Interestingly, the result is quite different from your RGB, showing that RGB is great in catching faint dust. However, the NB image revealed that there is also a SNR there. Cheers, Göran

I like the new version, which more clearly shows the nebulosity. The background still looks quite nice. This is a very odd lump of Ha, as @tomato just pointed out in his version.

Outstanding, really quite amazing so we all look forward to the final one!

Thanks! It is Sh2-88. Only a head so I assume it is dead😁

Thanks Alan! Or the Sicilian outer space connection😄

Thanks a lot Peter, much appreciated!

I think this image rather clearly reveals that these objects of the Sharpless catalogue (Sh2-86, 87 and 88) are part of a large complex of Ha-emitting nebulosity. I never combinded RGB and NBZ filter data (Ha+Oiii) this way before. The RGB data (ASI2600MC without filter) brought out much of the dark dusty parts while the NBZ data lifted the Ha structures. Stars taken from the RGB data. Processed with the latest XTerminator tools. I think Sh2-88 should be a contender for the name Horsehead Nebula. Data collected a year ago with my dual-RASA8 rig with ASI2600MC cameras. 95 x 3 min RGB and 61 x 5 min NBZ. Cheers, Göran

A great image and you captured it all Dave! Not often seen. I would be tempted to reduce the star field even more with the new XT tools - there is a lot of nebulosity and dust there. CS, Göran

Yes, just start digging into the hard drives on cloudy nights, or like me, when waiting for astrodarkness to come back in late August.

Yes Carol, I also wonder (or worry) about that soon happening, and someone else will be no one else, only AI.

Thanks! No DBE used but I used Gradient XTerminator in PS so maybe an effect of that.

Thank you all! Yes, it also struck me that it no longer looks like a DSLR camera image. I now checked my notebook and it was -3°C that night which may have cooled it enough to keep most colour mottle abay. Noise XTerminator also does a good job on colour noise.

Fully agree!
