All I’m saying is the Az mount does well enough on dso for my aspirations, I was not trying to say it was better or equal to an eQ, just that I have been taking some nice photos but would be nice to have some tools that correct some of the Az errors that Az users encounter. As far as my statements regarding Az becoming more popular for imagers…. I just mean for casual astronomers… just seems inevitable that tech from evoscope and Vaonis and sharpcap starts making it in to more setups and it will be a winning choice for amateurs entering the hobby…. I think it’s already been proven by Stellina that it’s capable of imaging photos that are very acceptable to even experienced imagers.
I get what you're saying, but I can only see it as a limiting factor and will end up frustrating new users once they try and push the boundaries a bit imaging wise. I mean, do you buy a car that only seats 2, if you have a family of 4, or do you buy a car that seats 4...
An EQ mount is not much more trouble to setup - really it just adds a bit more effort with regards to balancing in the RA and DEC axis, which in turn will help guiding, and will also remove any unwanted strain on the spur gears.
You could just do a rough polar align and plate solve with either the AZ or EQ setup I guess.
I am confident that the stars that you are seeing are a result of 2 things:
1. improper balancing of the mount
2. AZ and inaccurate polar alignment and tracking.
You can continue to try fixing them in software, but you will never get pin point stars with this setup imho. If you are happy with non perfect stars, then continue as you are. It is your gear, your hobby and your money and your time! I simply gave you an honest assessment of why you are seeing the issues that you are - i.e. answered your question. Your issues aren't, imho, really anything to do with astrosurface - it's simply applying a band aid fix to underlying issues. PixInsight can do similar things with its deconvolution tool, and I'm sure APP has a similar tool that can apply similar fixes. I just don't personally think that a software fix after the event is a good way to fix the issue!
