Many thanks. I'll give this a try.

That's an interesting idea. I don't mind the spikes though but I will look into it. If you have a link to the site you got the rings from that would be great.

The scope is mainly for astrophotography with a ZWO EAF most likely. Are the Esprit focusers any better?

It was closed down to F2.8. The spikes are coming from the aperture blades.

I have been having some fun with my Rokinon 135mm F2 lens which I have automated with an EAF using the Astrodynium ring set. It worked first time without any adjustments. This image was captured last month under exceptional seeing/ transparency conditions. It is only 2.5 hours of data in 3 minute frames. I was amazed how much detail I captured in that time. Its worth zooming in on the Astrobin image to see the fine detail. The weather prevented me collecting more data.

I am considering getting an FLT 120 in a few months time. I have heard that the focusers are the weakest point. Any more recent feedback from other FLT 120 users ? I am also considering the Esprit 120. It s about 2Kg heavier though. for my EQ6-R mount.

Hi I have a CGE classic mount which is about 16 years old now. It is still working fine and tracks very well. I picked up an AsiAir Plus recently, which I use on an EQ6-R-Pro mount when imaging remotely and I am impressed how easy it makes the set up and imaging process. I am looking to see if it will work on the CGE mount as it would be transformative. Has anyone tried to do this before? I assume it only connects via the hand controller.

Hi. I picked up a new FTL 91 last week and have the same issue getting focus with 1.25" eyepieces. I tried two diagonals, both William Optics but hit the stop just before focus could be achieved. Did this affect getting focus with your ASI camera? I am considering returning the scope to the dealer.

Either of these instruments should work well for wide field astrophotography. You will need a field flattener / extender for reach focus. I use a basic Skywatcher field flattener (can be found under different brand names) which does both and works well. Your T ring screws on the back of the flattener to attach your camera https://www.firstlightoptics.com/reducersflatteners/stellamira-2-field-flattener-with-m48-adapter.html Check the weight limit on your mount first.
