Quick Question!

[that_guy]

Does the Esprit 120ED have the same focuser dimensions as the 100ED?

[Ukastronomer]

depends which one there was an early and a newer one, the latest 120 I have is 3"

Isn't the ED100 the smaller 2"

I think the one you linked is the standard doublet ED100. I have the Esprit ED100 and it has a 3" focuser, if thats the case they should be the same dimensions, Thanks!

In that case they are the same, why ?

[that_guy]

I'm looking at different designs for autofocuser brackets. I'm in the process of making one but running in to issues. A member here was kind enough to give me his design on his esprit 120ED. He said he wasn't sure if they both had the same dimensions and neither did I. I just wanted to make sure before I wasted precious filament printing one. :P

I WOULD be most interested to hear from you on this thanks, you should have said in your original post ?
