Tak kindly supplied me with a brand new Mewlon 300 backplate from their new warranty spares......its not usually a separate order-able item so IMO they are to be commended for their flexibility in supplying it.
The original backplate is stashed away in spotless as new condition with the original model and serial number identification plate attached.
So there is no loss of value/investment in the scope as an original fit out
Open tubes also have issues with cooling and currents during acclimation which any open tube owner will recognise.
The Mewlon 300 Mirror and Mirror Cell are heavily over engineered by Tak and the mirror is reasonably thick so increasing Airflow to the rear of the mirror will significantly improve cool down time.
Air is drawn into the tube through the fans which are fitted with filters to remove incoming particulates and is blown directly against the rear of the mirror and mirror cell and vented out the front of the tube.
The Mewlon 300 puts up outstanding views when the mirrors are properly acclimated but it still takes time.
As Matt suggests I should gain a minimum of 1 hour or viewing time but with the mirrors being at optimised acclimation instead of half way there.
IMO money well spent on getting more time with better views
