Off axis position

[jambouk]

The celestron off axis module fits straight into the stepped down visual back.

Is it possible to fit it in after a crayford style focuser? Does a stepped down sct visual back - to 2" nose piece connector exist?

Thanks

The Celestron OAG comes with 5 Adapters 2 X 42mm male and female, 2 X 48mm Male and Female and a single SCT that fits on the scope side there is a Moonlite SCT to 2" extender that will screw into the OAG and have a 2" extention to that would go into a Crayford Focuser just be a case of sorting out the right type of Focuser....

Hover your mouse over the image to see the adapters...

Hi James

Yes they do make a 2" to SCT male thread adapter. I use one on my SE8 after the crayford. I then attach the 6.3 reducer and then the Celestron OAG onto the reducer. When I purchased mine FLO were out of stock, they may have them in now, I think they were about £22.00. I ended up getting one from Bern at MA as FLO were out when I enquired.

Bern can get this:

FLO sell this which has a smoother looking edge and a flange; which do you think will be better:

Its the thread pitch that needs to be checked, there's a 2" SCT and a 2" mm they won't screw together.......
