Greetings Peter,

You can match the Altair 'scope to your Nexstar by making a plate to replace the Telrad finder bracket with a mounting plate. You mount the OTA tube rings to this plate.

Please have a look at :

for some ideas. If one has the resources making a matching plate is quite straightforward.

Just check out the ADM dovetail plates for 8" SCT scopes and saddles.

You could get a 8" SCT V-dovetail to mount on your SCT (https://www.admaccessories.com/product-category/v-series/v-series-dovetail-bar/) and a small V-saddle (https://www.admaccessories.com/product-category/v-series/v-dovetail-series-saddle/) to mount in place of the dovetail on your guiding scope, so you are able to slide it back-  and forwards to obtain balance.
You may also need a set of guider rings, for example:  https://www.firstlightoptics.com/adm-guide-rings.html.
You may want the 125 mm diameter  rings, so you will have room to adjust the 72mm guider (?) scope.
