I have the following parts for a 20" f4 Dobsonian:
1. 18 point primary mirror cell, similar to an Obsession model- $200
2. 4" Ostahowsky secondary in an Astrosystems holder- $250
3. Spider- $30
All are in excellent condition. The pics I have are too large for cloudynights so contact me for images if you are interested. Prefer pickup but I can ship at buyers expense. I'm not setup for paypal so a personal or cashier's check or money order is fine.


  • Condition Excellent
  • Location Norman, OK
