I'm getting deeper into astrophotography and trying to do so on a tight budget (what else is new). At any rate, I presently have a permanently polar mounted 10"LX200GPS in a small observatory with a TeleVue Pronto piggybacked on top and Losmandy counterweights system on the bottom. I'm actually pretty well on my way. In addition, I upgraded focusing and replaced the Meade electric with a Moonlite 2 speed manual focuser which houses a focal reducer. (ask me how I like the Moonlite focuser.)
I'm presently doing my imaging through both scopes but only have one camera which is a Meade DSI III pro. I'm able to take 30-90second unguided subframes, but I'm not too happy with that.
I was using a laptop with 32bit Vista which, once Meade posted a USB/RS232 32/64bit driver worked pretty well until the laptop crapped out on me. My other options for a PC are an old Windows XP unit or a new Windows 7 64 bit machine. Yup, I'm using the old machine which works, but for how long is anybody's guess.
But I digress from my question(s).
I use both Envision and Nebulosity for capture and have tried PHD for autoguiding. PHD seems to work very well using either scope and I used it for PEC which made that operation simple, but without a second camera to image, autoguiding doesn't help.
It's time to get an autoguider.
My first question is: If a get a Meade DSI II to use as an autoguider how does PHD know which unit will be used for guiding and which is for imaging?
Second question: I have tried hooking up my DSI III through Envision to use as an autoguider but I keep getting the Error: Invalid IP address. Anybody got any ideas. I use Com 4 to connect to the scope through the Autostar Suite or The Sky the PC without any problem, but it’s a no go with Envision.
Third question: I’m also considering saving my sheckles for an SBIG ST8300 camera and use the DSI as the autoguider. Does anybody have any experience with this combo? I know the ST8300 is new but looks like a nifty unit.
Any and all input is appreciated.
