A Pencil and a Mistral

Well after 18months of trouble shooting a new setup. (Esprint 150 and a Moravian G3 16200 mono). And problems with my mount(G11) I've finally got something to show for it.

Overall very happy with the new gear. Still learning how to process NB images, which is compounded with still trying to learn PixInSight.

NGC2736 had some processing in PixInSight and NGC3324 just stacked and stretched. Need to drop a couple of the NGC3324 subs due to cloud which I'll get rid of when I add some OIII.

NGC2736, The Pencil Neb (22xHA,29xOIII @ 10mins 8.5Hrs total)
NGC3324, The Gabriela Mistral Nebula (27xHA @ 10mins 4.5Hrs total).


Bias and Darks used, no flats.

All comments, good or bad, welcomed.

Cheers

Looks like you'll be graduating from the beginners forum shortly John; nice, sharp pencil

Wow, nicely done. Great to see these out there on the beginner forum

I've been working on both of these with my STC duo filter. Have already captured Gabriela - but am having a hell of a time processing to bring out the green. Ditto with PI. I'm floundering trying to process it.

I've only started capturing the pencil. It's one beautiful target and you have captured it - get some more subs to bring out the background nebula!!

Thanks Tony,


Not sure about moving to the big boys/girls class just yet. I would hate to bring the level down.


Cheers

Thanks Chris.


I followed the Light Vortex Tuts to process the Pencil otherwise I don't think I would have gotten anywhere. Want to get some RGB for it next but that might have to wait till next season for that. Will get some OIII for the Gabriela next.


Cheers

I have never imaged that object, so I am wondering what the red blotchiness over the whole image is; is it Ha nebulosity, or a processing artifact, or noise?
Nicely done, by the way.

Hi Raymo,


Thanks for asking, I THINK it's Ha neb., looking at the subs. But I could be totally wrong and it could be bad processing of noise.

Nice work John!
Do you dither your exposures?

Also I think the background is faint HA signal rather than noise. Here is a H-alpha image by the Anglo-Australian Observatory showing a much wider field with nebulousness in the area.

Thanks Nathan,


The Mistral Neb. was dithered and some of the Pencil Neb was dithered. I was having some problems getting the SkyX to guide one night so I was guiding in Maxim and capturing images in SkyX and had dither turned on but it didn't dither. I thinks it was some of the Ha subs. I have a bad column in the middle of my sensor and dithering normally removes it but it is still evident in the Pencil Neb.


Cheers
