I have a question regarding guide settings
My rig is a Skywatcher Star Adventurer 2i, ASI Air Pro, Guide camera ZWO 120mm Mini, Guide Scope 120mm/30mm.
I use either a Nikon D610 or 5600 as my imaging camera with lenses from 20mm to 135mm
I've been using the default guide settings for the Calibration Step, max Dec Duration and max RA Duration.
I assume these relate somehow to the guide camera pixel size and focal length of the guidescope.
Does the calibration step refer to the exposure time when the guide does initial calibration? i.e. allows enough time between steps to get a reasonable star movement? If so then shorter for longer focal lengths (faster apparent star movement) and visa versa?
The values for Dec and RA duration I haven't been able to understand. I thought initially these related to guide exposure but that is set separately.
And what are the recommended values for a set up like mine (relatively wide field 135mm - 200 mm EFL on FF or cropped 24 mp sensors )
I've seen 8000 ms recommended for the SA with a 120mm guide scope...
I'd very much appreciate some clarification and guidance (lol) in respect of the above
Thanks in advance, Rich
