QSI683 Back Focus ?

[Davey-T]

Have been trying to image with the QSI683 and WO Star71 but given up because of the weather so have decided to try it on the WO110FLT but having trouble working out the spacing using the WO flattener 1V.

Presumably I have the medium body, filter wheel no OAG.

Any idea to save my brain ache

When you get the distance sorted fine tuning is easy with one of these Baader Vari-Locks

Got a few Varilocks various lengths but need a starting point

Just tried to edit this post as I put the wrong flattener pic' in but after editing I've got no save button ?

I think the save button is out of sight off the bottom of the screen, needs a bit of scrolling....

 

My Save button is over to the right under the "Reason for edit"  Box.

No got no option to save after deleting the image only cancel, so how do I delete and image ?

From the published data, (I used to have the FLT110 and flat IV and still use a couple of QSI cameras)...

The back focus distance from the shoulder of the Flat IV T2 thread is 54.99mm

The back focus of the QSI WS body (Filter wheel internal only) with the T2 mount plate is 35.56mm

Subtract the two gives you a T2 spacer requirement of 19.43mm plus you need to add 1/3 the thickness of the filters.

Here is the correct back focus document with dimensions in mm and inch for the 500/600 QSI cameras:

Here is a copy of the FLAT IV (WM68) diagram...
