Hello to all.

I recently purchased my dream scope, a TEC 140. It is used but seems to be very clean with the optics looking clear and nice. Looking forward to dark skies and imaging. It came with the standard 9 inch dovetail plates and rings. The dedicated field flattener came with it as well. Another nice piece of gear !!!

Anyway, my question to the group is if there is a longer(14 inch)dovetail plate that can replace(retrofit) the upper 9inch plate? I plan on piggybacking a 80mm guide scope. So I need a bit more plate for a secure attachment. I would like to keep the lower 9inch plate if possible. I've looked at Losmandy universal dovetail plates but I do not think the predrilled holes will match up to the ring holes of the upper rings if I keep the lower 9inch dovetail plate connected. I would like to be able to retract the baffle/dew shield without moving scope in the rings.

Any advice/help on this subject is much appreciated !!!!!

Sincerely,



Lanny Harwell

Lanny, I will simulate your situation with longer plate tomorrow and let your know result. Regards, Yuri

Lanny , I put longer plate on top of 9" TEC. This plate will not interrupt with dew shield. The only thing in question is how to connect both. TEC 9" plate has the central slot that could be used if the other plate has similar slot or threaded holes at the central line.Other option is to drill and thread one of the plates, we can do this small work here. Regards, Yuri

I have two 15" dovetail plates from ADM accessories and works well.

www.admaccessories.com/D_Series_Universal.htm

It would be best to use the following adapter to attach another scope instead of attaching directly to top dovetail plate:

Hi Yuri.Thanks for looking into this. I will consider the drilling option. It might be easier just to buy two(15inch) dovetail plates and attach the rings. My only concern was not being able to retract the dew shield.

Regards,

Lanny
