Why two 8” scopes... I was thinking of one complementing the other. An example is say the Bubble Nebula with additional nebulosity as well as M52 ( whatever the cluster is) in the same area. At f2.8 the area looks good but small - rotate mount and see same area with greater scale - the Bubble itself or the other objects without adding extra pieces to the Boren-Simon.
== I use the BS8 at f4 quite a bit // I use a filter wheel for either f ratio
== I have a TV 2x Powermate and tried a couple of times but I admit I need to try this again - the length of protrusion out of focuser (Wheel, 2x PM, NV device) looks extreme.
== the C11 is too much for me and maybe the AYO
== the 9.25 is a possibility
== the C8, u180 are possible
== u210 ($$)
The Mewlon f/# seem high - the Intes was M15, too high for NV.
Earlier today I sent message to TS as they offer an 8” RC:
My preference is to get a scope that will do well with NV and on moon and planets.
