PHD2 and OAG

#1

Post by Astroglide65 »


Hello everybody,
I'm taking the step and going OAG. My telescope has FL of 731 mm f 4.5, setting up a new profile in PHD2 I'm assuming I enter the FL of 731 mm and everything else remains the same since I'm using the same camera and same mount.

Thanks,
Dano

When I read this I questioned whether you need to change the pixel size on the guide camera. You indicate you are using the same camera, but if you were using a different guide camera before you changed to OAG, I think you would have to change the pixel size to match the imaging camera for the OAG setup. If your old guide camera pixel size is the same as your imaging camera, then that value doesn't have to change.

Sorry, I am not familiar with your old guiding setup. Jsut something to follow up on.

Old set up....R2 Imaging camera, 115 FL guide scope, ASI224MC imaging camera, 6" Mak-Newton 731mm FL.
New set up...R2 Imagining camera, Off axis guider, ASI224MC imaging camera, 6" Mak-Newton 731 mm FL.
Pixel size is different between 2 cameras.

that's pretty much it, then run through the calibration settings again to give you a recommended pulse guide size/ "step size" then calibrate on a star

Yes, use the guide camera numbers and the imaging telescope's focal length. PHD2 only cares about the guide camera. After you get your first successful calibration do run the Guiding Assistant. This will provide a lot of useful information and valuable changes to make to your guiding parameters.

Congrats on getting the OAG.

Cheers,
