I have a JMI DX-1 Focuser for sale. The unit is in great shape and includes the DX-1 unit, collimation screws, all original thumb screws, adapter, and original box with instruction sheet. You will need hardware to mount to your scope. The focuser has both coarse and fine focus. It is much smother than a DX-3 and you get the extra lifting capacity as well as the fine focus.
The focuser is the standard with a 10" radius curved base. The draw tube is not the standard but the optional 2.5" draw tube length (standard is 3"). See the JMI web site if you need more info on the specifics. Feel free to email me with any questions.
Price new is $259 and $7 to ship I'll take $185 for this shipping and insurance is included (UPS ground). I'll ship the day I get a US Postal MO or if you are in a project and don't need it today feel free to send a check and I'll ship after the check clears. For local pickup the price is $180 cash.
