I had decided to not go mono until I could afford (and justify) the cost of a ASI2600mm But then I got a "too good to turn down" offer of a used QHY 163m (the QHY version of the ASI1600mm) complete with filter wheel and an equally good offer on a set of ZWO NB filters.

 

So this is my first light with that camera and my first ever mono/NB/SHO image with my own gear and data.

 

It is 2 hours of Ha and 1.5 hrs each Sii and Oiii. Of course more time will help but nights are still short here. The Oiii was really poor because of the full moon and a high haze. The little Sharpstar 61 EDPHii does not like moon anywhere close and I had some nasty gradients and reflections in the oiii. Ha and Sii were fine.

 

I would really appreciate constructive critique and suggestions for improvement from those of you more experienced with mono and NB. Thanks in advance.

Very nice image!

 

For a test , some weeks ago, i tried with a OIII filter on the NA nebulae with my mono cam. It did not came out well either. Seems to have catched quite some data, but that combined with a color stack really just came out ugly....

How is the QHY 163M doing? Are you happy with the results?

 

I’m considering buying one as my first mono cam. I currently have the ASI2600Mc.

I have not really done that much with it to be honest. I have only done one other complete image with it which was just under  4 hours total which is not enough. But this is what I got

My expectations were fairly well managed - I knew that it was going to be inferior in some ways to my ASI2600mc and I knew that where I live, with the limited amount of clear nights I, get Mono with filters was going to be more of a challenge in terms of getting full data sets. That was always my reasons for going OSC in the first place.

 

But, that said, I find that the data coming from the 163 is pretty clean, there is virtually no amp glow to speak of and what there is is easily calibrated out. In terms of functioning, I use APT and had no issues at all getting things connected and running, including the QHY filter wheel that came along with it. There used to be talk of QHY Driver issues but that was no problem for me. So yes I'm happy with it. I need to get more time with it but the few clear skies I have had recently have been far more appropriate to the 2600mc. It was always intended as my secondary (back-up) camera.

 

So I'd say if you are getting it at a price that suits, and you manage your expectations (its NOT a 2600mm) then I'd say go for it.

Beautiful nebulosity in that picture. Good to know you can get decent results.
