can i see your Atik 460ex with 0.85 SW reducer set up

[Astroblagger]

Hello

Im trying to get the spacing of my atik 460ex and SW0.85 reducer set up. im reading the that the back focus is 55mm on the reducer, so 13.5mm from camera (to sensor), my filterwheel (scope technix) is 19.5mm so that leaves me 22mm to extend. what spacers extensions can I get for this?

There's an ebay seller offering 20's or you could go a 15 and a 6...

You need to add 1/3 of your filter thickness to the backfocus distance also.

The FLO baader shim set is what you need for the precision adjusting.

Hi

Here's mine

If it helps I have a 10mm and 13mm (23mm) attached to my reducer in the front of my filter wheel

It's a xagyl low profile wheel @ 19mm

I used one of the adapters in the pack that came with the camera (13mm) to attach at the nearside to the camera.

That got me 55mm in total

Just realised it's a skywatcher reducer and mine is a william optics, but I would have thought the measurements would be the same ?

Can you help me identify these spacers as this is what I had with my 314l iv gone and lost them though!
