Thank you very much Ray

Mr Gralak, I would appreciate any experience or thoughts about using the same pointing model when the camera is changed on the same scope . I realize that ideally one would want to redo the pointing m

Hi Marcelo, Thank you very much for sharing your experience. You are likely right that changing the camera weight could have an effect. Assuming that the camera weight is about the same, and the conne

Hi, I just installed a CDK12.5 on an AP1100. i am wondering whether the APPM pointing model would need to be done for each camera that I use ? The camera connection is quite rigid (ONAG) but of course

Thanks Much. Yes I have PEMPro (it came with the mount) and the PEC correction is applied. Does anyone have an answer to my question: ” after a large pointing model is done …does APCC / APPM allow the

Looks too good to be true ! it would be the bargain of the century Sam

Hi, Based on my limited research, it seems that temperature will have a bigger impact on refraction than barometric pressure - this is because of the magnitude and rapidity of change. Both are importa

Hi Dale and Sebastien- thank you so much, this is very helpful. I can see how temperature is important for the APCC model, but does anyone have an idea of how important barometric pressure or RH are ?

Hi I expect to receive my AP1100 within the next month. I am doing some reading to prepare. APCC pointing model requires temperature. I have 2 devices which provide temperature: a) Pegasus PPB; b) Opt
