Anybody got a rough idea of the back focus distance when using a 183C on a 200 DP Newtonian.. I’ve tried it directly in and through and extender and can’t see a thing, absolutely nothing!

cheers

A. Yes; 12 & 6 on a vertical axis.  You don't need the app to do the alignment - the Synscan hand controller will tell you where to place Polaris on the circle, but I do find it much easier to use the graphical representation of the app, than trying to guesstimate where exactly to place Polaris based on the time given by the hand controller. My polar alignments generally improved a lot by using the Synscaninit app, so do recommend it.

B. I put the scope roughly back in the home position after the polar alignment and before a 2- or 3-star alignment.

Cheers thanks for that will try that shortly as flat calm and totally clear here

Just a quick query as all the info on here and YouTube etc refers to the original mount, I was trying to find out about the polar alignment using the new reticule I.e. the one that has a notched ring like a clock face.

For those that haven’t seen it there is no longer a circle with a ring in it to put Polaris in!

A. Do you have to rotate the mount until the 12 and 6 are vertical and then align with app?

B. Then having done that, do you then go back to home before entering a target or do you leave it where it is.
