Altitude & azimuth calibrations, free to good homes.

Yes Scott, I think you've got it.

[Sconesbie (Scott)]

Beauty. I'm onto it.

Enlarging done tomorrow, then placed on the base.

Thanks for your help. This is going to make things so much easier if I can use Az/Alt measurements to find things.


Regards
Scott

What size have people had the pattern blown up to so it suits a bintel 10" dob?

[Allan_L (Allan)]

Richard scales them to fit.
So if you find the print file for the Bintel Dob (which is the same as the GSO Dob I think), then you take it to a print shop and get them to print it as is.
I am pretty sure there is at least one GSO 10" DOB print file in the thread.
I also recommend you have the printout laminated by the print shop too.
Not very expensive from memory.

The painful part (for me) was having to cut a "window" in the DOB base.
OR
I did hear of someone who had it printed in "reverse" so that it could be attached to the upper rotating part of the base. Sounds good, not sure how to put it into practice though.
