I think folks should calm down a bit - don't know if I'm considered a 'purist' or any of the other acerbic tags but my 2 cents was at the start, so my 3rd cent here.
It is always more difficult to advise responsibly someone who bought a scope FIRST and then said I want to do long exposure imaging but can't necessarily buy what they might benefit from most with remaining disposable income.
What I find funny is the comment about IOptron, have you looked at where your other choices are made? Guess what. I'll add that maybe your scope was made there too.
As a general plea I'd ask folks not to 'bash' by country of origin. There are far too many people here that would be on the sidelines if you were to somehow cut out the offerings from China. And frankly all the lower end gear. So try being thankful they understand our expectation that we get it all for a song and dance if that, and they are trying in a market nobody else is, and IMO there is a LOT of really nice toys for us - THANKS TO THEM. Without them almost no-one would be here. And too I'd ask not to be acerbic about A-P and SB, ASA, 10 micron who are delivering fantastic products to us which are truly 'hands off' but they want to be paid for all that attention to detail.
In the lower end and mid range mount range if you want to do A-P you are going to become more intimate with the mount. Maybe a little more than you desire, but I do not see that as a bad thing if it will give the results you are after. Read up all you can in the mounts forum. It is these mounts that provide for most of the activity, and there is a lot of great information there. This post may have been better placed there?
But to responsibly from experience say something is or is not up to task is just being honest. I think and hope folks appreciate that anyone is willing outside the sales and marketing staff at so and so to take the time.
Imaging is largely about the mount and not the scope, or even the imaging device. Call it non intuitive or whatever else you like but think about it. The mount holds and points the scope and imager. Any, and I mean ANY issue a mount has will show up in the image - no way out of it. This is why I say it's backwards here. By and large once you get your imaging / optics 'set' you just focus and don't expect a lot of variance, and that is a somewhat safe assumption. The mount, possibly same can be said, polar align and invoke auto-guiding and then... well a lot can show up, and it can be very different seeming, though the cause(s) may be an invisible common denominator.
Sure you can hypertune and toss bad subs and get a good or even great image. But the fact remains that it is an imaging system and the mount is the most important part of that system. So the mounts forum is where I'd spend my time, and I'd read everything I could going back as far as possible.
Don't be fooled by all the pretty pictures. It takes a lot to make them or even one.
We are lucky here to have the great folks (me included) that do give advice. Maybe there should be another forum for 'ADVICE I WANTED TO HEAR' but there isn't.
But there is a tremendous amount of experience and 'real world hands on' here and in the mounts forum that is free, from enthusiastic folks that love this hobby and desire to share from their often hard came by experience.
Heuristically there are a lot of mounts. First sieve 'cost' filters out some. Second sieve 'telescope type /weight' filers some. Third sieve 'long exposure imaging'... (I'm going to assume you don't mean that the way we do by long meaning over 10 minutes) a far more difficult sieve to pass. Fourth sieve 'easily portable' may further limit...
What makes even a bit more difficult is all the marketing and 'paper whipping' jargon and euphemistic specifications and as I mentioned expectations. No doubt there are folks that want your $$ and that should not come as a surprise.
To me that is where forums like this are worth their weight in photons. Much is possible, it just might be a little more effort than you thought, and you have a lot of well meaning help.
