Subject: etx 90 ra Sent: Wednesday, August 19, 2009 09:33:17 From: cremm (email@example.com) 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 phil....firstname.lastname@example.org 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.
