IC 5070

First attempt with ASI183GT MM and narrowband. This image is comprised of 30 4 minute subs and 15 darks shot through a 7nm Ha filter. Scope is a SW 80ED on a SW EQ6-R Pro mount. Not much post processing was done other that cal/int in PI with a little contrast adjustment. I was just excited to see how much detail comes out using a monochrome camera. At first I was having buyers remorse with this new camera and was almost set to sell it and go back to using my D750 but this changed my mind. I am sure if I go through my whole workflow it will look even better. This was taken unguided (I will be going with an OAG soon enough).

Looking good. I look forward to seeing the complete image

Haven't images this myself - nut sure why, probably just because I don't do much DSO during the summer months. But that looks like a great result. The detail in Ha is stunning and sometimes seems better just left as it is rather than adding OII and SII. 

I made the jump form DSLR to mono a while back and initially felt similar to you - wondered if I did the right thing. But if you can keep your workflow and processing simple ie avoid over complicating things I think it's well worth the effort. Whilst going through my bloated hard drive to clear out some space recently I went through a load of my DSLR subs which I thought were pretty good at the time - but no comparison to cooled mono!

Great picture!
Just a word of caution with OAG and refractor. I used (with some success) an OAG with a 72mm refractor. I say some succes as guiding was lost from time to time through loss of clarity in the star. My guiding graph was "OK" but was a bit saw-tooth like.
I then moved to a 32mm mini-guider and my guiding is now near perfect everytime - guide graph is almost level with minimal nudges.
This was the only change and my images are much sharper as a result.

The final image is of course the real test!

Best regards

..... oh ... and .... those stars look pretty good to me at 4min subs!!!

Some more processing done to get the histogram where I wanted it. This was after tvgdenoise and some further curves transformation.

Your well on the way, longer subs should get some nice images.
