"Phoenix Rising from the Ashes" - Part 2 (by Peter Laidler) (click here)

This interesting article is the second in a continuing series and it's accompanied by a photo montage, detailing the complete rebuild of a totally unserviceable, scrap Watson No.32 Mk2 telescope.

Article Extract .....

The Erector Assembly

Exactly the same as the ocular lenses only this time, the erector focuses the graticle and inverts both the grat and image to present you with your x3 image. This time, it’s the shallow large diameter convex radius curvature that goes into the cell first, followed by the spacer followed by the next lens, small diameter curvature followed by the counter cell that seats onto the FLAT surface of the outermost erector lens. But that’s not all….. Some lens sets were ground with BOTH outer surfaces slightly convex. If this is the case with yours, then it’s the shallowest convex that faces the OG or graticle, thus Shallow curvature, deep curvature, spacer, deep curvature, flat or shallowest curvature, counter cell.

As with reading any kind of article, whether it be traditional paper magazine based, or in this case an electronic format, it's sometime difficult to gauge the reader'sinterest level. Peter has requested that if anyone has any questions on his current series of articles, comments or additions for inclusion in his articles under the "Collectors Comments and Feedback" section of the MKL article, or ideas for future topics, that they please leave feedback for him in the appropriate announcement thread.
