I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.

After a number of poor results with planetary imaging, I am starting to wonder if the apparent poor seeing is caused by the warm air exhaust blowing out of the laptop. I have had the laptop positioned a few feet away from the telescope dewshield and blowing air in that direction. Aiming at Jupiter the dewshield etc is just a couple of feet higher than the laptop.
Next time I'll try to remember to put it on the other side of the telescope so it blows air away from it. But there are plenty of other things to think about while I am out there.
I connect my mount to PHD2 using ASCOM and most nights I have the error "Star did not move enough" as well as "Suspicious blah blah, axis may not be perpendicular". This does not happen when I connect the mount via ST4 cable. I read somewhere that I can do a Calibration Sanity Check in PHD2. I am however unable to find that function in the software. Is it some pop up feature or does it have a location in the settings/brain icon?
Any help will be highly appreciated.
I am ready to purchase my laptop, it will be an Intel core i7 with all the trimmings, my questions is regarding drive space and typical imaging file size output. Many new computers have solid state hard drives, they are much faster but space is sacrificed as even the upper end laptops have 256gb SS drives.
Somehow I feel that a 256gb drive will be low for an imaging laptop, I know I can add an external drive but I want to avoid carrying anything else. Maybe I should opt out of solid state and instead get one with a 1Tb standard drive?.
Or, am I wrong, and 256gb SS drive will do the trick? I have no idea what a decent range is for typical nights imaging or solar imaging sessions.
it is getting really cold and this is the first time I'm using laptop in the field for imaging, so I have no idea how to use the laptop in subzero temperatures.
Last year when i was checking something in Stellarium, my screen just froze and did not work until i had it warmed. I get that it is Liquid Crystal, and will freeze in subzero temps. So how can i use it in the filed, all night long, without freezing it to death?
