Soooo - I may have built another telescope and not documented the process at all. Which is a bit of a problem as I now have a folder full of CAD files with really odd, but meaningful, names (like: "SlottyThings.ipt", why did my past self do this to me!). Luckily I have some nice work in progress photos, even if my in depth description may be a bit lacking.
The telescope is a 76mm Newtonian reflector with a potentially equatorial mount. The optical tube, and mount were built using the university laser cutter. Unfortunately I am not yet skilled enough to make the mirrors, mirror cell, tripod or eyepiece myself, so they had to be purchased/scrounged.
The optical tube with the two cheaty elements, the secondary holder and the primary cell. I like the fact that it looks like a big ray gun! |
Drama shot, now with proper mount. There have been a couple of modifications since this photo to stiffen up the mount and tripod, but essentially the telescope still looks like this. |
Of course no project would be complete without an even more ambitious project to follow it. Thus, "Operation Sandra Voi", the plan is to produce a mosaic image of the moon by stitching together lots of smaller images. My eyepiece's field of view is quite limited, so this is the only way I can produce a complete picture of the moon, and hopefully it will look really good when it is done: I can always go back and re-image sections that are either incomplete or of poor quality after a first pass.
"Sandra Voi" is named after one of the lighthuggers from Alastair Reynolds's Revelation Space series, only mentioned in passing a couple of times, it is an exploration ship just as hopefully the project will help me explore astronomy (ha ha, maybe I should have come up with a cool acronym instead). The naming scheme does leave me with a bit of a problem as I haven't thought of a cool enough project to call "Operation Nostalgia for Infinity" yet...
