JMI NGF-S focuser with large format visual back adapter and DRO. Focuser et al is in very good condition. I changed to an Optec TCFS a year ago because I needed the temperature focusing compensation for all-night unattended photometry runs on my 12" LX-200. Brand new cost from JMI is about $550 plus shipping. Offering for $400 plus shipping (say $10).
