ps As we discussed, added 60' vernier.
Will post pics ASAP |
Thanks Richard, I will print out the 60min internal vernier and let you know if any of the measurements need adjusting, but otherwise looks perfect.
I understand why 60 mins can't be accommodated in a 30deg arc without increasing the main scale gradations, so will just stick to the 60min vernier.
should be able to fix it to my dob in a few days. will post pics once done.
thanks
