Discussion Overview

The discussion revolves around the tracking error of a telescopic scope mount and its implications for astrophotography, particularly in relation to the C11 optical tube assembly (OTA) and its compatibility with various mounts. Participants explore the performance of the mount for different uses, including imaging and visual observation.

Discussion Character

  • Debate/contested, Technical explanation, Exploratory

Main Points Raised

  • Some participants share personal experiences with the C11 OTA and its mount, noting that while the optics are excellent, the mount may limit performance for astrophotography.
  • One participant expresses interest in taking pictures and stacking images, indicating that the mount's tracking capabilities are a significant consideration.
  • Another participant suggests that for planetary imaging, the tracking error may not be as critical, referencing successful imaging results with a specific camera setup.
  • A question is raised about the adequacy of the EQ5 mount when used on a permanent pier, indicating concerns about its tracking performance.
  • One participant explicitly states that the periodic error of the mount is a major drawback, suggesting that a permanent pier does not mitigate this issue.

Areas of Agreement / Disagreement

Participants express differing views on the significance of the mount's tracking error, with some downplaying its impact for certain types of imaging while others emphasize it as a critical limitation. The discussion remains unresolved regarding the overall adequacy of the mount for astrophotography.

Contextual Notes

Participants do not reach a consensus on the implications of the tracking error, and there are varying assumptions about the types of imaging being considered and the specific equipment used.

Any first hand reviews on this scope?

My telescope is the same C11 OTA on a much beefier mount. If you plan to take pictures, the mount will be a serious limitation, but if not you should be ok. The optics, however, are excellent.
 
I would like to take some pics, stacking if necessary. I saw this scope for 1999 on an equatorial mount. Was intrigued. If you like it, that is all I need to know.
 
Will the the eq5 mount be adequate on a permanent pier?
 
The tracking error (periodic error) of that mount is the real killer - a pier doesn't help that.
