Ok so i want to get into astrophotography on deep sky objects and i'm about to pull the trigger on a few items

>iOptron CEM25P equatorial mount - used good conditions 600€
>Canon 600D (Rebel T3i) Astromodified - used 200€
>SVBONY 70/420 ED apochromatic refractor - used 350€
>SVBONY Canon adapter with 2" light pollution and UV/IR cut filters also SVBONY - around 150€

I also plan on adding a guide scope and camera setup with an Asair mini for autoguiding, error correction and dithering in the future. And also an autofocuser, maybe.
Has anyone had any experience with this gear?

astrophotography is entirely gear based and is a giant endless moneypit maw. you can't do it cheap.

It has a 12kg maxmium load, the gear i plan to use shouldn't exceed half of that.

I will think about a cooled dedicated camera once i get some experience under the belt. Right now i don't want to spend 1500€ on a camera alone just to regret it afterward.

I almost forgot about the bathinov mask but i found some cheap ones for 20€. Anyway is a takahashi scope that essential? Are there any list of good scopes i could take a look?

quality gear will *not* lose value, and you can just resell on as you upgrade or lose interest. e.g. a takahashi scope used is almost always 70-80% of new price, even models that are 40+ years old
you dont need cooled astro sensors, but astro modified cameras are a waste of time, a relic from before dedicated astro sensors were cheap and plentiful. see first line above.
hot aliexpress garbage like svbony is throwing your money away.

subtract mount weight from payload weight, and you're neglecting counterweight and accessories

Isn't weight limit reffered to the scope side alone? I read in a bunch of forums that people are mounting 5 kg of equipment on 10kg mounts like EQ5 so i assumed it didn't account for counterweights and head.

center balanced mounts can exceed the "50% Rule".

Thanks for confirming you don't know what the fuck you're talking about. Capacity calculations NEVER include the counterweight.
Direct from iOptrons website:
>Payload 27 lb (12.3kg), exclude counterweight

Camera Weight: 515g
Scope Weight: 2.2kg

OP has plenty of room for additional gear and the CEM series of mounts is very well regarded.

Mounts fine, camera's pretty old though. I would imagine it gets outperformed by non astro modified cameras with more modern sensor tech.
Don't have any personal experience with SVBONY but people seem to like them for the price.

You don't need an asiair unless you REALLY want to lock yourself into the ZWO ecosystem and control your stuff from a phone/tablet. You can just use NINA and a windows PC to run your guiding, alignment, and imaging session.
