6-inch refractor (Was: Re: Journey to the 1.8 meter)
I agree, Mat. Erik settled on a good all-around configuration. I have a few 6" refractor builds in the line-up as time and budget allow. My CGEM tripod may not extend high enough so I'll probably be making a new mount and tall wooden tripod, or seeing what the used market holds, when the time comes. Too, the CGEM might be able to handle the f/10, but isn't adequate for the f/15 Jaegers project. I may build a pillow-block mount for that one, using some of the old components Siegfried gave me (thanks again Ziggy!), if I don't go with a Gerrish permanently attached to the house, or a camera-obscura/Coude' setup going through the no-longer-used swamp cooler ducting up to the roof. Of course, most or all of this may have to wait until retirement, a few more years away. I heard through the grapevine that Steve Fisher sold his 8" D&G but kept his 6" (where are you, Steve, we miss you!). With refractors, seems that going from a 6" to an 8" is physically a much larger step than the same aperture increase with Newtonians.

It is not the size of the boat but rather the motion of the ocean.
If my personal situation was different I think I would build a 18" f4.5, for a portable scope. I agree, Mat. Erik settled on a good all-around configuration. I have a
