...We have checked with Parks, and the mirror is back from coating and the telescope is in assembly. It should be completed and tested by the end of next week. Yours truly, Richard" Gee, I hope they don't rush it through, and perhaps, cut a corner or two... I should never have called! Alan |

I have the DX3, and it is a real beauty! I have it on a home made 10"
Dob with a Parks mirror (which is sweet) also. On Thu, 06 Nov 2003 17:29:17 -0600, Alan W. Craft wrote: On Thu, 06 Nov 2003 15:16:44 -0800, Mike Simmons wrote: "Alan W.

base. Howard Lester There's no need to keep me in suspense, Mr. Lester. Why, then, should it be with a 5" radius base? A 5" radius makes a perfect fit onto a 10" diameter tube. Their standard base is a 10" radius, and that would make for a fit that is very sloppy and difficult to square to the tube. Mr. Howard Lester |

I custom ordered this one, an 8" f/5, and for placement upon a Vixen GP-DX, and instead of an f/6 with its extra 8" of tube length. Parks makes an 8" f/4, but I wanted something to seesaw between visual observation and astrophotography, but secondarily for the latter if and when the mood strikes. Parks regularly offers the f/4 and f/6 ratios for their 8" mirrors, o.t.a.'s, and complete systems. My request for an f/5, and not unreasonable given that I'd have to wait just as long for an f/4 or f/6, happily coincided with Parks's experimentation with a small batch of 8" f/5 primaries, and due, I suspect, to the 8" f/5 Syntas et al flooding the marketplace. I hope you've a dark-sky site that's convenient, if not right outside your front door, and to make good use of the 10". Alan |

Mr. Howard Lester I went to JMI's website, and I see what you mean. I'll be contacting Parks and Scope City as soon as possible, and then report back. It's always something... Alan |
