.... the sale-out continues
I have a 12.5" F16 DK Cass OTA for sale.
FT rotatable RP focuser... a joy to use.
All mirror cells are adjustable. The OTA is ~26kg so a G11 class EQ mount is recommended, however my new AZ EQ6 handled it fine in AZ mode... see my other adds for the AZEQ6.
I did a lot of work on redesigning the parts, but there is room for improvements. The OTA is a thick wall alu tube... weight reduction is possible by replacing it with open truss-tube design. The optical design is similiar to Takahshi's Mewlon.... a corrector-flattener-baffle is available and may be suitable for this.
The Mewlon's primary is F3, this is F4 ... someone with ray-tracing knowledge can have a go at it and turn it to a CDK... for much less money.
Primary mirror cooling fans installed, and Losmandy dovetail on radius blocks included.
Warning: this is a HEAVY and big instrument... meant to be for permanent installation!!
Price: $3800
/trade-ins welcome... laptop/DSLR/small APO happy to negotiate
(in the pics diagonal, Baader Zoom, PSU not included in the price)
Thanks for looking,
Mick
