Cant focus ?

[Blaze 1]

Really stuck on this one . Im a newbie first use of a Bresser Messier NT-150S/750 Hex-Focus last night.  The telescope is collimated with a DSLR fitted to the telescope directly ( T2 ring onto 2 inch adapter ) it will focus in the mid point of the focus travel (brilliant no problem) .

As soon as I fit the supplied eye piece that came with telescope I cant focus the focuser does  have enough travel  , it needs to be wound out further than it can travel . Tried using the barlow as well and that is the same also if I use the DSLR with the barlow same problem.

Anything other than prime focus with a DSLR I cant get it to focus so I can do anything visual with it which is a bit disappointing as my daughter and myself were hoping to observe Jupiter last night.

Any help would be greatly appreciated

There should be an extension piece for visual use.that fits onto the focuser drawtube. Unscrew the top part of the drawtube and fit the extension piece in place.

You are far from the first not to realise that there is an extenstion piece hidden in the shipping box of a newt scope with a hexafoc focuser. 🙂

Luckily you didn't throw it away with the packaging, either!

Not me - but someone I know of , did (not on this forum)!
