    Default Advice on suitable camera for dob



    Hi Everyone,

    I´ve been trying to do some astrophoto using my 8" dob and MS Lifecam HD-3000 webcam. I think I´ve managed to get the best from it and would like to do a next step.
    38918529_2051953375022084_1072573601485422592_n.png

    What I have in mind is a new camera not a new telescope just yet. I considered ZWO ASI 120 MC or similar equivalent but I don´t have any idea whether it is suitable for my setup in terms of getting into focus etc.

    Please advise

    Thanks

    What do you want to image and how do you want to do that? Also, are you using an equatorial platform so that you can track for a while? Or does your Dobsonian have their GoTo system?

    What kind of price range is acceptable?

    Given the sub-forum you are in, the focal length of your telescope, and the ability to image a variety of targets pretty well I'd be suggesting looking at the ASI294 Pro. Not the cheapest option, however. . .

    At this time I only image planets using short videos and stacking the frames. No tracking necessary - I just let the planet driftt through the field of view, stop the recording and repeat.
    Price range is ideally under 200

    That is a great image of Saturn...and using a webcam! Well done!!

    ZWO's ASI224MC is widely considered to be a great planetary webcam but may be a bit out of your price range. The ASI120MC-S is less expensive and a solid planetary performer but I am not sure that you will see much of an improvement over your current webcam.

    ASI224MC is actually not that far from my price range (in €). I guess my only concern is if I will be able to bring it into focus. I´ve had this issue with my current webcam so I had to improvise

    I have used both the Lifecam 3000 and the ASI 120MC. The ASI will make a noticeable difference. Focus is not usually an issue for video cameras: they have shallow bodies, unlike DSLRs, so do not need a lot of back focus.

    The ZWO cameras should come to focus in a Skywatcher dob. The sensor depth is pretty shallow. I use an ASI294MC Pro with my 12" Skywatcher Goto Dob. The lip on ZWO cameras is a 2" diameter. So it can sit in a 2" focuser hole or a 1.25" hole with the nose piece attached. You'll get a little more infocus room by placing it in the 2" extension if you need it (no need to remove the 1.25" nosepiece from the camera). Also, on my scope, there's an extension required for eyepieces (either a 1.25 or a 2" depending on the eyepiece). If your focuser is the same, and you need more focus room, you can remove that 2" extension and place the camera directly in the focuser hole.

    Ive used an ASI120mc in my dob, focus was never an issue and the performance was good.

    There are a few 'newer' cameras than the 120 but it has served me well and it's hard to beat the price.

    The price of the cameras with the smaller sensors is very attractive. . . But since your method is to aim and let the target drift, you may find the experience more pleasant if you use a camera with a much bigger sensor.

    The bigger sensor means you have a wider FOV which will tend to mean that it will take longer for the target to move through the FOV and you will thus have fewer pointing adjustments and less wasted time. You might find the ASI294 Pro to be a really good choice.

    However, the tiny sensors are only going to "see" targets which are at the center of the FOV. This means that the aberrations which are much more pronounced in the periphery are simply avoided with the tiny sensors.

    If you choose to use a bigger sensor you would now be imaging in part in the portion of the FOV which is going to have the increase in distortions. This may mean you would have to consider getting a coma corrector like the Baader MPCC if you were to use a camera such as the ASI294 Pro.

    I'd probably opt for the bigger sensor my self, but others needn't choose the same.

    Oh, and you should see some of that work done by Robrj. I consider it to be amazing what he is doing in a very short period of time!
