Last week I was given the unique opportunity to test the new ZWO ASi 6200 MM PRO camera.
Please understand that I am in no way affiliated with ZWO and I am not paid for this review and these are just my initial findings.
Also I'm not a professional reviewer so please bear with me.
This camera uses the latest 61.2 MP Sony imx455 sensor.
This is an initial review with a description of the camera and accessories along with first impression and some test frames.
I received the camera last week and unfortunately the weather has been bad. Now I’m on a two-week trip in Europe and I won’t be able to actually use the camera under the stars until the first week of December.
The setup came with the camera, the 5x2” filter wheel and a new OAG.
Fit and finish and assembly:
The camera feels very compact and light, like a beefed up ASi1600. It is the usual ZWO red anodized finish .
It attaches to the filter wheel with four screws that are accessible through the carousel itself. You will need an open filter spot for that so either it needs to be done before the filters are installed, or you will need to remove one of the filters.
The camera has a 17.5mm backfocus from the front plate and the front connection is M54x1 female threads. In addition to that there are four tapped holes to attach the filter wheel through machine screws.
The filter wheel also has M54 female threads on both faces.
The OAG looks and feels very solid and it has a fine focus mechanism for the guide camera. The clear aperture is about 63mm and it has an M63x1 female threaded connection on the camera side.
I really like how the components assemble together with machine screws instead of threaded connections. This assures that the pick off prism is at the top of the sensor, thus minimizing potential shadowing.
I was able to quickly figure out a connection to one of my scopes (Sharpstar 150mm f2,8) using m48 threads. This however will produce some vignetting. I suspect that one will end up with a bunch of custom adapters for the various scopes.
I still need to figure out a way to connect it to the FSQ 106 which will be the primary test scope.
Cooling and power:
The cooling seems to be very solid. My room temperature was around 21c and the camera was able to rapidly reach the temperature of -5c and maintain it with the cooler at ~55/60%. The power consumption in this state is about 1.5a which is excellent.
If I wanted to lower the temperature to -10c then the cooler usage went up to about 80~85%
At 100% the power draw hovers around 2a.
Cooling much lower than -5c may not be necessary given the very low dark current.
I have attached a few unpacking photos and the following posts will have the links to the calibration frames.
I will be happy to answer any questions or specific requests.
I'm sorry that I won't be available to run any further tests or imaging runs until two weeks from now.
