Guide Pixel Scale and PHD2?

[Michael Heald]

Hello! I'm wondering if I should update my guide camera, and I would appreciate other's experiences.

    After another breakdown of my 8" LX200 running at f6.3, I demounted the OTA and plan to run it on a Ioptron HEM44. I use a SGIB ST402 with photometry filters. Most of my exposures are 60 seconds or less, though some are up to 5 minutes, especially in B filter.

    I've never had good success with guiding with my SBIG ST-i and 100mm guide scope at f2.8 with the LX200 mount. Lots of streaked frames, which I presumed was from the mount.

    The pixel scale ratio is about 10.0. I would like to run the set-up fully robotic, and I can get an updated guide camera. I'm considering a QHYCCD5III with 2 micron pixels.

    Would I see an improvement in guiding by updating the guide camera? Best regards.

Mike

Hi Mike

it would be best to upload your guidelogs so we can see your results and give you feedback based on your data
