To add to the fun and games with using a DSI on an ETX 125 I have made a
simple but effective modification. Using existing screw holes I made a
simple but rigid  bracket to move the finder over a tad and allow for
the USB cable to be plugged in. I intend to make another with a with a
more appealing shape and better workmanship but the idea is sound.

Of the enclosed pixs no 19 shows the OTA in it's vertical position





and no 22 shows the new bracket  when in this position, I think there is
plenty of room for manoeuvre within these parameters.





Pic no 9 though shows the DSI mounted 180 degrees about so the USB
socket points to the right on the ETX125 this leaves plenty of clearance
between the viewfinder and DSI because the viewing tube on the DSI is
offset A picture sent to me from Stephen Bird shows that this should
also be a viable position for 90's & 105's.

I have been having an email discussion with Stephen and one of the
points that I raised was that in this reversed position  the Autosuite
control panel on the PC becomes invalid as far as direction and tracking
is concerned. Upside down and back to front.





This begs a question is there a person using  your site that has the
ability and the inclination to write a software patch to correct this
problem. This could be of tremendous benefit to existing and future ETX
users.

As a post script to my last email I feel that I should have clarified
what I meant by the Autosuite control panel.

The imaging program for the DSI is different from the LPI. In the DSI
program you can have control over the telescope direction and focusing
whilst using the imager.

Here are the relevant pages from the manual in case you have not had a
chance to catch sight of them.






Kind regards Charles
