That's a great small rig.

except that he didn't mention about a filter wheel and filters, and the flattener for the scope; he'll need a flattener at the bare minimum

everything else seems fine, OP might possibly need to get dovetail risers so that his filter wheel (or even, camera), doesn't hit a tripod leg when scope is pointing near zenith

if he doesn't want risers, he can get a pier extension, that's another way to do it

Is the weight limit on the AM3 a little low for that setup?  The AM3 lists 17.6 lbs without a counterweight, and the Fluorostar 91 is 12.3.  Then add the camera, filters and guiding stuff.

Personally, I think I would pop for the AM5N.  I use the AM5 and I really like not having to deal with the counterweight.

Big cost difference though...

533 is a pretty small sensor so he might be ok with it to start. You're right about the wheel and filters though. That's gonna add a penny...

Ya, Sorry I forgot to mention filters I'm still looking for them. I'm also not trying to exceed 5,700$ but I might consider the AM5 mount

I have a similar setup, so I’ll provide my opinion:
Go for a bigger mount (AM5, NYX-101, iOptron). This will give you room to grow.

You could stretch your budget by skipping the PowerBox, for now, unless you need dew heaters.  It helps organize everything, but I don’t think it’s essential. Doesn’t the ASIAir have 12V outputs?

If you’re technical, you could use a Raspberry Pi running StellarMate or your own OS. This can save you a little money, and you’re not locked into the ZWO ecosystem. However, it’s not as easy to use, although StellarMate has made some big improvements. They also have their own hardware, which includes power management.

I'm not sure that the OP made it clear if this was a system he's putting together or if it's a pike of gear he's getting used. If it's all part of a package he's not going to have a choice of mounts.

EDIT: Ignore my comment, I should read the thread before I post...
For a monochrome camera mabye you want to consider a filter wheel or filter slot and filters. Or do you plan to do only monochrome images?

Just, I'm wondering how to install risers it looks hard. And a little later ill probably upgrade to the Quatro 300P for deep sky imaging.
But not any time soon

just get a pier extension for now  https://agenaastro.com/zwo-200mm-7-9-pier-extension-for-am3-am5-mount-pe200.html?srsltid=AfmBOoo41EmEhiQBmqHlPRkBfzuGtL0gKYH3-C-V4jWp-3IGT9_K6dTc

you could look into risers later when you get the newt, if you need them

definitely buy the AM5N instead of an AM3, if you plan on buying the Quattro

Can an AM5N handle a Quattro 300P ... that's a giant telescope!

so far he has only said he's looking to buy an AM3 and might consider an AM5, so that's why I recommended the AM5N

but I actually looked up the weight of the Quattro right now and found out it's about 57 pounds  it's a beast, I was thinking it would be like 30 for some reason

he should get a GEM then, a beefy GEM like a CQ350, if he plans to get a 300P

If you’re thinking of a 250 or 300 Quattro, I’d probably go GEM.    I have a 250 and has an ioptron hae69ec, and while it tracked ok, that was a lot of weight on a big lever arm.   Polar alignment was a pain due to shifting of the mount with the az screws loosened to adjust PA.   

maybe start with a smaller used mount and then sell it when you decide to upgrade to a larger scope.

GEM mounts are much heavier, but the counterweights mean that the mount head is balanced on the pier/tripod, which makes Polar alignment less troublesome.     You're not going to have a very light and portable setup with a Quattro 300.    Even the 250 that I have is not very portable.   And since it's so large of a diameter, the weight is well away from the mount head so you have to have a mount with a much larger capacity than the weight suggests, and the wind catches the large newts so the need for a heavy tripod and mount are even greater.    I have my 250 and AP Mach 2 on a Ioptron tri-pier on a JMI wheeley bar and roll it out of my garage and then put it on wood blocks to level and make solid.   I wouldn't consider transporting it around through.

I have both AM5 and AM3. I got the AM3 later for smaller, more mobile setups and have never regretted that.

It works great for me with a 135mm lens, Redcat 51 and 65PHQ refractors as well as sometimes a 150Quattro. All of theses work fine without the pier extension. For 80mm I did use the pier extension iirc. With a counterweight you should be fine for quite some time. 13KG is quite a handful. I never exceeded that even with my larger system.

What is the powerbox for? I run all my equipment off the Asiair without issues (both plus and mini).

Sw website says 300p quattro weighs 57

I assume that's pounds.

That's a big heavy wind sail for an am5 right?
