Decision on Pulsar dome treatment - advice please
JeremyS replied to JeremyS's topic in DIY Observatories
I had to look it up. I never knew that was a thing 🤔. Might it work? I initially thought you meant those French wrappers: or the other kind of wrap artist -

Sucks down the baffle. It’s to supplement the plastic container approach -

Yes, there are few videos of Dirac speaking in later life. I wanted to hear his Bristolian burr, that the book made much of, but it’s barely detectable to my ear. -
Good idea 👍🏻

Not familiar enough, Alan. Does the slit open beyond the zenith and is the slit wide enough also for your future upgrade? I suspect so, just checking. Great to see it comes with 4 inbuilt khazis 👍🏻

Looks a very nice job. Congratulations! Do you know which colour it is? Looking at their colour chart, Holly would be closest to my current colour. I would like a gloss finish. I dread doing the whole thing and not liking it. I wonder if I could try a small area at the back to test. -

Thanks William. Mine is the older Pulsar. The dome and the walls are each single pieces, not quadrants. -
There has been much discussion on here about how to deal with a deteriorating fibreglass dome with the aim of making it look shiny new again. I have tried various waxes (including v expensive Brazilian boat wax). I even had my car valet wax and polish it once. Looks great for a few weeks , then back to matte. I also did a few treatments with polytrol. This lasts a few months and is much less effort. So today I visited a bespoke fibreglass manufacturer who does a lot of work for the likes of English Heritage, cathedrals plus less esoteric jobs. He said the problem is the gel coat is completely shot. The surface is now microporous and soaks up wax etc. Gel coars can last up to 20 years, which is the age of my Pulsar obsy. Tbh parts of the original gel coat weren’t brilliant anyway. The gloss gel coat only comes from the original mould, so I will never get that back again. So he said I have the following options. 1. Purchase new obsy 2. keep on with the ultimately fruitless wax or polytrol in perpetuity 3. use a 2 pack automotive paint. But this will never look like new, requires skill to apply and nasty stuff that should be done indoors. Not something I would entertain doing myself 4. Paint on by hand a gel coat. It will never be gloss and looks a bit crude. Often used on fibreglass roofs, but these can’t be seen so their appearance doesn’t matter. He could produce a same and quote for the job. I am thinking about 4. Any thoughts?

Travel eyepiece setup (for 100mm Takahashi)
JeremyS replied to Neutrinosoup's topic in Discussions - Eyepieces
My lightweight set that I took to the Texas eclipse ( sometimes use the Pan 24 instead of the Tak LE 24) for my Tak FC 76DCU The Leica Zoom is impressive. Sometimes use that. -
Simply splendid 👍🏻

Rare for me, but this was a book that I couldn’t put down. Fascinating read. Full of interesting characters and not just Dirac. Thanks for alerting us, @ollypenrice
