Obsession 18 inch f/4.5 Classic
I have been doing more imaging than observing for the last few years. I made the hard decision to sell my 18" Obsession Classic f4.5.
It is serial number #0874 and has the following features:
- Argo Navis
- Servocat Gen 1 with wireless and wired hand pads
- Feathertouch dual speed Focuser
- Mirror: Galaxy Optics, Premium Select #1 from Batch ($450 paid for this option) with Enhanced coatings
- Installed Astrocrumb 2" filter slide and case
- Installed Markless DSC Stalk for the Argo or other gear with custom cloth case
- Wiring to UTA for 12V Upper cage with power outlets for accessories
- Powered AstroSystems Dew Heater for the secondary mirror
- Dew controller on UTA and dew straps for eyepiece and finder scope
- Obsession Black nylon Shroud
- Wheelbarrow handles/wheels
- Cables for servocat, argo PC connection
- Telrad with powered dew heater
- 100 Amp Hour deep cycle battery with heavy duty power cable
- 3 Amp 12V power supply to run system off 110V
- Custom canvas bags for poles and stalk
- Custom nylon covered carry box for UTA
Everything is in good condition and well cared for. I washed the mirror and checked it and the surface looks good except for several small light stains. See the picture. I doubt that these have any effect on image quality but I want to be upfront for any potential buyers. The wood frame has a few cosmetic signs of use.
Pick-up in Allentown/Reading Pennsylvania area, I maintain an observing field near my house and live in a fairly dark area, so arrangements can be made to do some observing with the scope. Payment via cash, cashier's check, PayPal (add 3%), or personal check (must clear before delivery).

A new system would cost almost $13,000 with the above features.
Asking Price: $5000
Thanks for looking!
