For longer than I care to admit I have had a UO MPT (Multi Purpose Telescope). Basically an 80mm f/3.7 refractor with what was probably a binocular objective. Anyway I finally figured out that it was being vignetted by the 1 1/4-in focuser so I re-tubed it with some PVC pipe and a 2-in focuser. The PVC tube and the lens cell were exactly the same OD. So, I wrapped some duct tape (what else!) around the connection and it worked for a couple of years. Then, a few months ago, I picked up the scope and it just fell apart.

A trip to a specialty plumbing store turned up a "PVC Connector". They are sold in various sizes and not expensive. I paid around $4 for this one which made my little scope much more robust in construction. Not shown is the rubber connection tube which was not needed for astro use.

Thanks for sharing. It looks nice and we won't know if you don't say it is pvc pipe connector

Total Trolley - 3 step ladder, push/pull trolly, fold up flat doly, thand up truck - all in one. Great for moving my dob to set up location am then acts as ladder. Works great for all ecept very small kids which would need a 4th step (3-5% on public observing nights - for these young ones, dad has to hold them up and 10-25% of those are tired and refuse to look)

Just picked up a flexible plastic (kydex?) yard 'For sale's sign at Lowe's. Plan to spray-paint one side flat black (the printed side), cut it in half length-wise and use Velcro or two-sided tape to put together the two pieces and use as a dew / light shield for my home-made 127mm refractor.

I'll post a picture when completed.

Bob,

I already have a can of flat black spray paint I bought at Lowe's too for the interior of some 80mm scopes I built. One tube was PVC, the other was metal. Seemed to work out fine. Don't recall the paint brand, but I'll take a look. I liked how flat an unreflective it was, as I recall.

The paint I plan to use on this dew / light shield is Krylon Indoor / Outdoor Flat Black. The can calls it good for wood, metal, wicker, glass, ceramic, masonry, paper and fabric.

Doesn't specifcally mention plastic or similar, but I've used it on PVC with no issues. 'Course, that was inside a homemade refractor tube. Not much wear and tear there!

I mentioned to my spouse that I could really use some sort of small zipper pouch to hold various hex keys. She gave me this!

I have been using larger pill bottles for EP cases. The longer ones allow some padding and a silica bag to be included.

Also:
-dew shield from a black snow slider and some stick on velcro
-a $8 three legged folding stool from CT that is just the right size for sitting at my 8SE
-$1 camera bags from yard sales for carrying EPs, batteries, filters etc
- $10 cooler from a yard sale that perfectly fits the box my OTA came in and also has a separate compartment at one end for solar filter, notebooks etc
-gear keepers (http://www.gearkeeper.com/) for keeping things close to hand
-dollar store red vinyl table cloth and rubber bands for enough flashlight covers to outfit several scout troops

Has anyone tried adapting the batteries used in garden tools (e.g. hedge clippers)as a power source for some astronomical devices? I know the Ah might be low, but it might be useful for small devices.

I'm an unskilled newbie. I usually have to have someone load batteries into a flashlight for me.

Having said that, if I ever survive a nuclear holocaust, I will want to hang around with you people.

I have used a guitar amplifier stand as a stand for the bag of my Televue TV85. It serves well as an eyepiece and accessories stand next to my telescope during observations.

Recently I purchased a Black and Decker cordless weed trimmer. It came with two 20 AH lithium batteries. Very impressive performance. Since one battery will last for three yard trimmings the other battery begs to be converted to astro use. The batteries are compact and lightweight to boot.

Sheesh! Finally got back to this little project! A dew shield from a very inexpensive plastic "For Sale" yard sign from a hardware store.

First, I cut the sign in two using a straightedge and razor-cutter:

Spray-painted the "printed" sides of the sign with multiple coats of flat black paint... Cut one of the pieces to the length needed to make a dew / light shield by overlapping about an inch and a half with the other... Used two-sided carpet tape to connect the two, reinforcing the edges with black electical tape... and joined the two ends with adhesive-backed velcro strips. Very inexpensive!
