Guiding with KStars/Ekos/INDI

[Gina]

About to try guiding again and wondering if the ASI 174MM would be better than the ASI 120MC-S for guiding with 200mm f4 lens for my dual imaging rig using 105mm lenses with ASI 1600MM-Cool imaging cameras.  I bought the 174 for solar Ha imaging but won't want to use it until later so have it available doing nothing ATM.  Differences are mono v colour, more pixels and bigger pixels - IOW bigger sensor.

Hi Gina, did your guiding work or does the previous non-guiding mystery still prevail?

I don't think that pixelscale matters much at your focal length. The same goes for fov; both are large enough at your fl to provide plenty of stars to guide on. The 174mm doesn't have a bayer matrix, and should be more sensitive because of that.

I haven't yet tried guiding since it failed to work a while ago but plan to to try again when we get the next clear night.  Maybe tonight.

Fingers crossed for you it was just a temporary glitch.

I'm all set up for trying guiding tonight.  Sky is clear with no haze.  Had to abandon the ASI 120MC-S as it wasn't working.  Recognised but wouldn'i capture an image.  I'll take a look at it later.  Put ASI 174MM on instead and refocused for that.

It's working!!  Yippee!!  Found it's own star, calibrated and started guiding.

0.87" rms at a pixelscale of 5.9"/pixel. That's good guiding.
