New bolts

So, yes, I am now into astro-spectroscopy! :)
One of the big secrets about spectroscopy with reflective gratings, that few people mention, is that it can get heavy! So heavy, in fact, that your telescope may find its way into impossible balancing situations!
In order to balance the weight, I had to improvise "stuff" attached to the telescope tube in order to balance it.. It worked, but was not a pretty sight.
Today I went to the historical "Casa dos Parafusos" (bolts house) and bought 4 screws to attach a larger accessory plate to my mount so that I can attach a counterweight more securely. This 65-year old shop had a really historic feel to it, a few years ago. Two years ago I found it closed. It went through a lot of difficulties, but the PECOL group managed to "save it" last year. I was very glad to finally see it open and working! The shop was completely transformed! It now has a modern space with stuff on display, it has two desks for attending costumers, and big warehouse with all sort of bolts in stock. The shop is no longer a tourist destination, but if you need an odd bolt or a common bolt, it is still the place to go!
