Skywatcher HAC 125DX Autofocus

#1

Post by Howzat »

I took delivery of the Starizona 3D printed autofocus kit for this small fast reflector. All fitted very well with ZWO motor focus. Ran a focus scan in Sharpcap and achieved 2.2FWHM. that is far better than the 3.5 to 4 I can achieve focusing manually. Adds a new dimension to this cracking budget RASA.

Hi,

that looks neat - from the look of it, a bracket, toothed push on outer for the focuser, and a toothed cog and belt. Simple but elegant :)

cheers,

Robin

Here are three pictures from last night with autofocus working. They are the processed .png files from sharpcap live stacking tweaked for exposure in Lightroom. Pleiades and M42 are 45mins of 15s exposures. Andromeda is 10mins of 15s exposures.
