Where can I get foam for my case?

Posted By Pat Plunkett

Try JoAnn's Fabrics or any other fabric store. I've gotten foam there MANY times!

Posted By Pat Plunkett

For cutting the foam, I use a trick my "crafty" wife taught me (and the same one they use at JoAnn's)... Use an electric knife! Make sure you wipe off the turkey guts first, though! Seriously, this is the best way to cut it.

Nice! I'm sure you know that streaking of Jupiter's moons is normal when you're stacking images(?)

Have you checked with Bob Royce? I never had a problem corresponding with him. His website is:

From a 12" to 8" what do you think?

Posted By Pat Plunkett

I went from a 12.5" Dob down to an 8" Dob... I know it's a different question, but similar results. You will lose a lot in galaxies and globular clusters, but to me the added portability is a real plus. Were I you, I would seriously consider a 10" truss-Dob. You really wouldn't lose much in the way of deep sky and you would still have good lugability.

Good luck!

I've never done this to someone else's picture before, so please don't be offended. I saw real possibilities in your picture and did some cropping and manipulation to come out with this. If you don't want it up here, let me know and I'll just delete it...

What are the tradeoffs of a zoom eyepiece?

Posted By Pat Plunkett

Since I bought my TV 8-24 a couple of years ago, I have significantly winnowed my eyepiece collection. I bought it for convenience but find that I use it almost exclusively. Sure, the field gets narrow, but I don't find it objectionable. When paired with a barlow, the range of magnification is really nice - from 4mm all the way to 24mm! You do have to switch the barlow in and out to obtain this range, but not as big a deal as trying to figure out which eyepiece to grab and then worrying about lens caps, etc.

I also find the zoom REALLY nice for star watches. The big, wide-field eyepieces are great, but newbies seem to have a lot more difficulty positioning their eyes with them. Plus it's nice to just bump the power up and let someone see the difference.

40 year coating effect on star test and foucault???

Posted By Pat Plunkett

I'm probably wrong (I usually am), but did you do your Foucault testing with the mirror removed from the mount? If not, does the rill coincide with one of the mirror clamps? I have seen something similar in a mirror with an over-tightened clamp.
