Hi! Well, go ahead and shoot, we'll compare). Aperture 200 is already decent for planets. And an ADC is desirable, even for our latitudes. SVBONY 3x is not very good. Their best one is the cheapest 2x.
You can't gain experience just by shooting.) I have a Levenhuk 2.5x, it's higher quality, the lenses are wider and the coating is better. But I had a problem with focus with it. I'll try again. Maybe I was doing something wrong.
It's through shooting that experience is gained! I'll help with whatever I can. Try the Levenhuk again. For 2.9 nm, it's desirable to push it further with an extension tube (Barlow body without the lens). Or buy an SVBONY 2x, it costs 1650 rubles. In your case, it can be pushed with one or two extension tubes. The best Barlow is 2x magnification, a wide lens (a cemented doublet), blackened edges, but with extension. With an ADC, it's better to screw the lens directly into it. This is all from my experience. I used to shoot with an SW150/750. And beyond that, it's steady hands and His Majesty the seeing.
Yes, I unscrewed the lens from a cheap Svbony 5x and got a spacer for magnification, but I didn't use it together with the Svbony 3x. In my opinion, from the balcony there isn't enough brightness and altitude at the time of shooting. I can't shoot Saturn at its maximum altitude, the balcony ceiling and Saturn's angular position relative to the balcony get in the way. That's why I suggested shooting together somewhere out in a field outside the city where the sky is cleaner and there's less turbulence from the city bustle) But if you're an introvert or too lazy to get out there, then fine) But I could tag along in your backyard, if the conditions are good there and you don't mind a stranger)
Of course I have an ADC, but I haven't used it properly yet. I haven't even figured out how to use it correctly. I inserted it once without knowing what I was doing, turned the knobs, and got no result. I only noticed that besides increasing the light from the object, there was even less light. But yeah, atmospheric dispersion is there and it needs to be fixed, well at least at the altitude where I could shoot Saturn from the balcony. That's no more than 35 degrees.
SVBONY 5x is the cheapest Barlow I've ever come across. It should be thrown away along with the eyepiece holder.
Shooting planets from a balcony is bad. A good result would be a small miracle. I can't go out to a dark site, it's too much hassle and would take a lot of time. And shooting in my courtyard is not an option, for various reasons.

Here's a very good article about ADC. Yandex Browser translates it perfectly. https://skyinspector.co.uk/atm-dispersion-corrector-adc/#ADCPrismOrientation
