No problem, Leo.

One thing I learnt early on, doing planetary imaging, is that a good finder scope, well aligned with the main OTA, is necessary, otherwise planet hopping with the camera mounted is difficult due to the very small field of view.

So I made a decent finder mount and knocked together a finder scope, using a 1.5" diameter achromat from my junk box, that will allow me to do the initial testing. The achromat has a brass housing and it is engraved Waterworth - Hobart. I did a bit of digging on the internet and discovered an interesting story about optics manufacturing in Tasmania: https://www.asap.unimelb.edu.au/bspa...waterworth.htm
Also, I think I finished figuring the secondary mirror today.
