This is one of the early black OTA's and has the ribbed sand cast mirror cell as opposed to the newer flat back cell. There is a small crack in the corrector near the secondary holder (see picture below). I have contacted Celestron and they feel it does not present a problem. It is not in the light path and does not degrade the image. This OTA gave great images last summer and fall. I have since installed Bob's Nobs but have not had an opportunity to collimate on a star. I have done a rough daytime collimation though. OTA is in fair to good condition. Shows its age and could use a paint job. Optics and coatings are in great shape.

The following items are included:

1. One Losmandy dovetail plate.
2. One Celestron Visual Back.
3. Bob's Nobs (installed but collimation needs tweaking)
4. Celestron trunk style case with factory foam.

Due to the crack in the corrector, the price was $950 shipped to CONUS. Contact me for more pics.

PRICE REDUCED TO $850. I will go no lower.

Thanks for looking,
Don Wyman
