Hi
Built the guide scope using a finder scope and a QHY5 L11 mono high sensitivity camera
https://www.bintel.com.au/product/qh...SABEgKc2vD_BwE. Always had a suitable guide star in the field and phd guided very well at this scale. Helical focus on the scope lens - bit touchy, but works OK.
Asking $150 collect adelaide or +postage.
Please pm if interested. Thanks for looking . Cheers ray
