SH2-112

Thanks Darren. I have not seen any 'common' name on this - in my mind it is "The Hole in the Wall" Nebula   

"The Hole in the Wall" Nebula - I like it! 

You got me interested in that object Brendan.

Here is my attempt from Dundrum.

25 300s Ha and 21 300s O3.
Clouds rolled in before I could get S2.

Hi Michael - very happy to see you giving it a go. As you can see you are already getting a lot of structure. I hope you can keep going with it. The Ha is as usual the strongest signal here but it is always worth getting the OIII & SII to make a final colour image - when they are both there of course.....which here they are.
Whenever, if ever, you can get back to this then I think that more Ha (along with getting the SII) will help increase the SNR even though, as I said, already you are getting great depth to the image.

I am sure you are quite pleased with what you have got so far.....it is looking really good for the exposure time. Others will take heart that even from Dublin - narrow band filters offer so much opportunity for some great images.

Looking forward to seeing this again if you get the opportunity to add the SII. Even if you don't get the SII - the HOO colouring is really nice....but do try get more Ha to help the SNR.
Brendan.

Thank you for the kind words Brendan.

I noticed that I have less than half the imaging time you have.
The weather for Tuesday is promising for another hour or so.

Michael.

 I was trying to put in a thumbs up .....beyond me I am afraid.
Brendan.
