A Robert Ferguson Observatory project to build a 40-inch reflecting telescope. Scope of the Project. Flat is the goal. Posted May 7, 2013. Our original Bath interferometer layout (here) has been changed to reverse the position of the camera and the laser. Each color crosshair circle is an igram, labeled with its angle of rotation. The closer the crosshairs are to the doughnut “mean” near the center, the better. On the way to Flat – Bumps ». Leave a Reply Cancel reply. Enter your comment here. You are com...

A Robert Ferguson Observatory project to build a 40-inch reflecting telescope. Scope of the Project. Scope of the Project. The VMOA acquired a 40-inch telescope project that was already being built by an amateur telescope maker in Stockton, CA to start the project. The acquired parts include:. 40-inch mirror blank, ground to F/3.2 at the 200 grit size, including the mirror grinding tool. Mirror cell with 27 point flotation supports. Secondary cage with secondary spider mounting. Make adjustments to the m...
About | Project 40
https://project40.wordpress.com/about
A Robert Ferguson Observatory project to build a 40-inch reflecting telescope. Scope of the Project. Optical design that brings the eyepiece for observers at a constant height of no more than 48 inches. This requirement should allow the telescope to be operated with nothing other than a small step ladder on public nights. Altazimuth mounting to minimize the cost of mounting fabrication, computer driven mount for tracking and finding objects. Open truss OTA for ease of fabrication and minimizing weight.

A Robert Ferguson Observatory project to build a 40-inch reflecting telescope. Scope of the Project. Star Test – Chapter 2. Posted July 29, 2012. Off to the Free-ATM experts list for evaluation. The experts concurred about some kind of astigmatism, but Mel Bartels also noted some “strong undercorrection particularly in the central zones with a modest turned edge and possibly modestly overcorrected midzones.”.

A Robert Ferguson Observatory project to build a 40-inch reflecting telescope. Scope of the Project. Engineering: The subtle art of constantly discovering you’re doing it wrong. @tensory. Posted April 28, 2013. Seven months and twenty-two days ago I posted the beginning of our interferometry odyssey. We are hardly at the end, but it seems time to send out an update(! An interferogram from October 2012. As a team, we have certainly been getting our patience bone exercised with this work! 1 comment so far.
