Quote:i've made telescopes from both the berry book and the berry/kriege book. i made a standard sonotube/plywood 6 inch reflector with a mirror i ground myself and right now am finishing up a truss tub 8" that is straight out of the berry/kriege book.
you have to do some adjusting for an 8 inch, but plans from both books will make a telescope, if you have the time, the tools and the drive to do it.
eta,,,,i also had the plans from the sidewalk astronomers, but i preferred the berry book for my first scope. i also had more and better tools. no surforms in my shop.
Quote:So I have found some plans online from the Sidewalk Astronomers folks in California. The plans have you building everything including the spider and focuser. Being a veteran of the Coulter plumbing wonder focuser I am a little hesitant about make a folder out of cardboard or wood.So I am doing some searching of some other plans and am thinking about two booksBuild Your Own Telescope by Berry (the library has it and I have requested it). The library has the 1st edition and I see it has been updated to a 3rd edition so I am going to thumb through the 1st edition and see what it has. I understand technology has come a good distance since the 1985 copyright of the 1st edition.Also I have discovered that The Dobsonian Telescope by Kreige has 8in plans. Has anyone actually used those or can recommend them? I don't have access of that book at the library unfortunately.I have the The Modern Dobsonian by Tom Clark, which I have been reading through and making notes. I really like his 6in f/8 dob he has in it. Might try making a clone of that.
Crazy ATM 6" F9.4 Newtonian first light July 2011 8" F/5.6 Dob, first light June 2003 12.5" F/5 Dob, first light Aug 2007, as well as 9- 4" f/6 mirrors. In progress:12" f/7 on quartz, 18" F/5 on BVC, and a set of 3-8" optical flats All optics by yours truly.
All MY reflectors are apochromatic. I am personally covered with infrared detectors and emit at 295 Kelvin, 24/7. If I were to recieve a spin entangled photon before you recieved its twin, MY photon would predict your photon's spin. Every time. MY family's lineage goes back over three billion years and has a whole branch of science devoted to studying it... The most Quotidian of observers
