17mm Baader Hyperion question

[Keithp]

Hello all, one of these little (big) beauties was delivered yesterday and I have a question about it.

It comes with an integrated barlow in the 1.25" fitting, if this is removed to use the 2" part of the lense what focal length is it then?

i.e. is 17mm with the barlow part or without the barlow part?

No complaints about it though, lovely piece of kit.

Regards

Keith, The 17 becomes about 22... Have a look at http://www.alpineastro.com/Hyperion-Eyepieces_com/Images_and_Docs/Hyperion_Manual_1.pdf the table in the top left.

Got it, cheers for that
