Post by Taipan » Fri May 25, 2018 1:57 pm

Anyone used any tiltadaptor with the LS50 and achieved focus?

The problem is to reach focus with the tilt adapter inserted between diagonal and camera. Baader Planetarium sells an ultra short C-T2 adapter, I use it to focus my Chameleon and taking full discs with my Lunt50, I'll try it with the tilt adapter in place and I'll let you know.

Unfortunately the lack of back focus is one of the limiting factors in using the LS50 for imaging, and was a big part of me moving to the LS80. I could get it to focus with the 50 by removing the B600 nosepiece and screwing the blocking filter directly to the back of the focuser with a T adapter ring, and using a QHY174 which you can poke all the way down through the eyepiece holder and tilter to get the sensor right on top of the blocking filter aperture. You might not be able to get the ASI120 close enough.

OK, my LS50 reaches focus with the tilt adapter, provided the short C-T2 connection is used.

I installed the FT crayford focuser and I no longer have the original one, so I can't compare them. Sorry.

Just for info.. It didn't work for me. Can't reach fokus with that adaptor and T2ti-ti ring. Guess i just have to live with the nr or take them away in PS. But thanx for help and tips.

I did not notice any change in the available back focus when I changed from the stock helical focuser to the Feathertouch on the LS50. I went down this road too.
