I have a Celestron 8" SCT connected to an AVX mount via a 13" Dovetail bar which I've been able to balance successfully until this week when I bought an ASI1600MM camera and 7 slot EFW. Now the SCT assembly is back heavy and I'm not able to balance the mount in the Declination due to the added weight and the limited length of the Dovetail bar to clamp the mount to due to it's shortened length. The total weight of the SCT and camera train is only 18 lbs, so the AVX should be able to handle it, but it's heavy on the camera side.
One solution would be to buy a longer Dovetail bar so I could slide the bar to the front of the mount bracket for better balancing, but I have not been able to find one online.
Any suggestions or other solutions I'm not seeing?
I've attached some photos of my gear to show what I'm talking about.
