134_3485 134_3485 Date: 05/27/2003 Pretty sophisticated homebuilt telescope. Two fans bring mirror to ambient temperature. Nifty digital thermometer shows how close the two are.
134_3486 134_3486 Date: 05/27/2003 Whole telescope, very compact and light, for its size! Probably 25" aperature?
134_3487 134_3487 Date: 05/27/2003 View of minimalist base. Not sure about stability, but light! Equatorial base too!
134_3488 134_3488 Date: 05/27/2003 Homebuilt solar telescope. Self-powering too! Uses a DayStar solar filter, I think, which needs heating.
134_3489 134_3489 Date: 05/27/2003 Beautiful telescope made with wood.
134_3490 134_3490 Date: 05/27/2003 Tube made from long thin pieces of wood glued together. Gorgeous!
134_3491 134_3491 Date: 05/27/2003 Typical Dobsonian setup. This is where I want to be in a year or two.
134_3492 134_3492 Date: 05/27/2003 An 18" Dobsonian. Nice wooden mount.
134_3493 134_3493 Date: 05/27/2003 The fork mount for a Meade 16" SCT. I have never seen a mount this gimongous in my whole life.
134_3494 134_3494 Date: 05/27/2003 A REALLY minimal 8" Dobsonian telescope. Absolutely tiny.
134_3495 134_3495 Date: 05/27/2003 Closeup of the base. Uses springs to counterbalance struts and secondary assembly.
134_3496 134_3496 Date: 05/27/2003 Another view of the super-minimal telescope.
134_3497 134_3497 Date: 05/27/2003 This is a 32" behemoth. About 10' tall!
134_3498 134_3498 Date: 05/27/2003 Big secondary assembly, big secondary mirror! Covered to avoid dirt and dust.
134_3499 134_3499 Date: 05/27/2003 Lid over the 32" mirror. Struts connected with metal mounts & knobs.
134_3500 134_3500 Date: 05/27/2003 Close-up of eyepiece mount and strut mounts.
135_3501 135_3501 Date: 05/27/2003 Another intense solar observer. The telescope was stopped down to about 3" or less.
135_3502 135_3502 Date: 05/27/2003 Very homey telescope - "Sirius Looker". Big aperature though!
135_3503 135_3503 Date: 05/27/2003 Gotta love having a 6"-8" finder scope...
135_3504 135_3504 Date: 05/27/2003 Secondary mirror housing is a bit suspect, but I suppose it works!
135_3505 135_3505 Date: 05/27/2003 A really lean and mean Newtonian. Note only 6 truss tubes instead of 8.
135_3506 135_3506 Date: 05/27/2003 Very lightweight, thin secondary assembly. Struts mount with knobs.
135_3507 135_3507 Date: 05/27/2003 Equatorial mount. Pretty sizeable counterweight. Impressive.
135_3508 135_3508 Date: 05/27/2003 Another view of secondary assembly.
135_3509 135_3509 Date: 05/27/2003 How's that for a worm drive?
135_3510 135_3510 Date: 05/27/2003 Who knew the "Least portable. Telescope. Ever." would be built into a trailer??
135_3511 135_3511 Date: 05/27/2003 Horseshoe equatorial mount; good for big scopes, but awfully bulky.
135_3512 135_3512 Date: 05/27/2003 Wires ready for cameras, illuminated reticles, controls, everything! Great feature.
135_3513 135_3513 Date: 05/27/2003 Good ol' Obsession scope. Lovely.
135_3514 135_3514 Date: 05/28/2003 Split-block clamps are used to hold struts on most Obsession Dobs.
135_3515 135_3515 Date: 05/28/2003 Another view of the split-block clamps.
135_3516 135_3516 Date: 05/28/2003 More astronomer humor. I guess.
135_3517 135_3517 Date: 05/28/2003 A little 10" Dobsonian. The guy who made it explained how it's constructed. He can break it down and take it as carry-on luggage onto a plane!
135_3518 135_3518 Date: 05/28/2003 The big brother Dob, by the same gentleman.
135_3519 135_3519 Date: 05/28/2003 Four struts!
135_3520 135_3520 Date: 05/28/2003 A lovely Dobsonian, made from very nice wood and then finished. It was for sale!
135_3521 135_3521 Date: 05/28/2003 Secondary assembly. Interesting way of connecting the struts.
135_3522 135_3522 Date: 05/28/2003 Base of the wooden telescope. Pretty standard.
135_3523 135_3523 Date: 05/28/2003 Detail of the struts and how they connect to the secondary assembly.
135_3524 135_3524 Date: 05/28/2003 This behemoth is a homebuilt spectrohelioscope.
135_3525 135_3525 Date: 05/28/2003 A friendly person explaining the theory behind the spectrohelioscope.
135_3526 135_3526 Date: 05/28/2003 The first mirror in the optical chain - is flat, and directs the sun to the second, parabolic mirror.
135_3528 135_3528 Date: 05/28/2003 The first mirror has a couple of worm drives for electronic control.
135_3529 135_3529 Date: 05/28/2003 This is where you look! Controls for frequency, direction, and other such things.
135_3530 135_3530 Date: 05/28/2003 The older guy in the hat is the one that built it! Quiet guy, but very friendly.
135_3531 135_3531 Date: 05/28/2003 People enjoying the spectrohelioscope.
