Hi,
I bought the Meade LPI-G as a replacement for my previous guidecam. I connected everything during the day and did some testshots through the guidescope with Sharpcap.
Up to that point everything seemed fine. But when I setup my rig at night and tried to do polar alignement in sharpcap I noticed the framerate of the camera was about 1fps with an exposure of 250ms.
Fiddling with the settings I could sometimes reach 4 fps but stil way to low. I tried binning by 2x2, lowering resolution, 8bit / 12bit, Raw / RGB , no real improvements.
I connected via the Ascom drivers I downloaded from meade, aswell as the Meadecam drivers. Both options delivered similar results.
At that pooint it was getting dark and I started to guide with the camera. Same problem here. PHD2 would often skip frames because the camera did not manage to take another frame within 1.5s.
At this point I thought my USB connection was maybe to slow, but when I fired up SkyCapture, which came with the camera, I get framerates that sound plausible.
SkyCapture manages 4fps, Sharpcap only does 0.5fps
Any idea what could cause such behavior?
Edit:
I think I found a workaround:
You can connect the camera through the "Windows WDM-style webcam camera" option in PHD2 and choose the "MeadeCam" option. This way PHD2 does not connect through Ascom but through the meade driver itself.
Will report back tonight if it improved the framerate.
Edit:
Setting the camera as webcam did the job. It required some more settings in PHD2 but I managed to get it to work consistently.
