ref ETX90 RA
would the optics be better now than mine bought about 98.and if so, when
did they change, in case i buy a secondhand etx 90.
can you buy dec drives for this model.....
thank you      uk.
Mike here: The optics for the ETX-90EC (and ETX-90AT and ETX-90PE) are the same as the ETX-90RA. New coatings (UHTC) became available in 2002. The new coatings allowed about 20-25% more light to reach your eye. As to adding a DEC drive to the ETX-90RA, see the Accessory Reviews: Miscellaneous page; JMI has (or used to have) a MotoDec available for the ETX-90RA.
