And that shell on the door is for when someone asks him if his dob is a cannon....

Let's put it this way I wouldn't be surprised if Homeland Security would check it out if the 12" dob and that were set up on the deck. :roflmao:

They'll have to pry the 79mm shell from my cold, dead hand.

I found an "Ironing Board Chair" while searching for books at a thrift shop. It works very well as an observing chair, and only cost £3 pounds British, or about $4.50 cents in US funds.
Never seen one in the States, but they are common here in the UK. This one was made in Italy, is height adjustable and very sturdy.


Now THAT is a really great idea. Looks like it'd be pretty comfortable to sit on, too.

Sadly I don't have anything cool to contribute. The extent of my homebrewing, so far, is using a Stanley FatMax tool box with a slide-out bottom drawer to put my EPs and Telrad, and the top "chest" part for things such as flashlight, iPad, books, etc.

The more things I can carry in one case means less trips in and out of the house.

Just want to say that this is a great thread, read all 21 pages in one sitting and will probably do so again because there are so many great ideas in here.

Its comfortable enough. A nice feature is that it folds flat for transport; its lightweight also.

The red caps from Coke two liter bottles fit right over mini-maglights very snug.

Recently I scored a very nice old binocular, a Bushnell Custom 10x50. Very nice optically and mechanically. But there were no eyecups. I checked around and rubber eyecups to fit these rather large eyepieces were priced too high IMHO. What could I use to make some with?

After scrounging around in my basement shop I found a box of rubber band type thingies. These were placed on the hinges of new doors to protect them during shipment. When we built the house 9 years ago the workmen merely tossed these in the trash pile. Of course I saved them. You never know, right?

They were just the right size, neither too tight or too loose. A quick snip of the scissors and a cleaning and voila! Rubber eyecups for free. :grin:

Here's an unusual item. It started out as a setting machine for my high school's volleyball team. They wore out the ball mechanism and the custodians thought of me and my predilection for astrotinkering when told to dispose of it. I removed the 152 pounds of steel plate counterweight and added 2x10 planking and half-bungees to hold down the GEM's tripod. An old snow shovel handle steers it like a dream.

I don't know if this still holds true, but the large round containers that Baskin & Robbins use are the perfect size and fit for using them as robust dew shields on C-8 and Meade 8" Schmidt -Cassegrains. You can even get them in unused condition so you don't have to eat all of the ice cream before using them. :-)

There are music sheet holders one can buy that are designed to attach to a wide variety of tripod legs and are designed to hold books open and sheets of music in place. I have found they are also great for holding and displaying large star charts on my telescope tripod while I observe. The one I have is adjustable can handle material of varying thickness and could easily handle a tablet computer too.

These music holders can be found online cheap or in most music stores.

Wal-Mart sells some camping mats under the "Ozark Trails" brand for under $8. They make great foam for custom eyepiece cases. There is almost no smell, so outgassing should be kept to a minimum, the foam is nice and firm for good support, and several layers are easily glued together with hot glue.

Here's a grab and go eyepiece case I just completed. The case is a MTM Case-Gard pistol case I bought for under $10. The bottom eggcrate was replaced with four layers of foam cut from one of the WM camping pads. The top three layers were glued together with a bead of hot glue along the edge and a bead down the center. The openings were cut with an X-Acto knife. It takes some effort to close the case, so the top eggcrate is in compression and should hold the eyepieces tightly in place.

In case anyone is interested, these are the eyepieces I use with my Astroscan. Top row from left to right: 25mm Orion Sirius Plossl, 28mm Edmund RKE, 20mm Astro-Tech Value Line Plossl, 6mm Agen EWA (Expanse clone). Bottom row from left to right: 15mm Astro-Tech Value Line Plossl, 10mm Orion Sirius Plossl.

I do not observe in winter without the wife´s hairdryer, on a longish extension cable. Waft a bit of warm air over a dewed up objective and it clears as if by magic. Similarly it keeps the business end of my laser pointer warm and functioning. And I use it to warm my hands.

Saw an interesting chair today when I walked by a Medical Mobility Shop. Its called a "bathlift", has a rechargable battery operated motor, and a hand controler.
It adjusts in a height range of 2 1/2" to 19", all at the push of a button. This could be the ultimate portable chair. Attached to the top of a wooden box or a crate made to suit, it could fill the bill for many applications. I am going to look into this further.

Here is a photo of a brochure with the website.

I use a very similar chair, Mike. Mine's "Vileda" brand. It's quite good for observing with a Dob and way cheaper than the Astronomy-specific ones.

The silver aluminum insulation scraps for Heat,A/C duct work make great dew shields!! even the Silver Aluminum tape makes a nice looking seam.
A couple minutes inside in the warm will hold in slight heat to help for dewing, then either slide it onto the tube for storage or fold in half and store in your Accy case where it works as a dust shield!!! since they are made from metal fiol they are tough and last for years, are feather light, a light spray of primer then Ultra Flat black paint gets rid of reflections.
Then you can make your Child a Robot Halloween costume with the rest....
Have fun.
