Hi all, how's it going? I'm not sure if this is the correct forum for my question. If it isn't, my apologies. Could a moderator move it to the correct one?
I have an older blue livery Sky-Watcher Skymax 127 that I bought off Marktplaat, (a Dutch/Belgian online trading site) for a steal. The scope works well. I wanted to go a step further and make it work fantastically. I decided to flock the tube and give it a good servicing and cleaning. The primary mirror had so much dust and grime on it, I was considering planting potatoes in it. The secondary mirror just needed a few puffs of air. There was a really annoying red fibre stuck on the back of the meniscus lens. This was causing a huge dust bunny in my Lunar images. The scope definitely needed cleaning.
With the help of a plumber's strap wrench, I managed to remove the meniscus lens cell and primary mirror cell. Thanks to Baader Wonder cleaning fluid, a Baader Optical Wonder Cloth, a gazillion Kleenex tissues, a good rocket blower and a quality camel hair brush, the cleaning and flocking went really smoothly. Here's the part that went wrong. There's a rubber O-ring that sits between the primary mirror cell and the telescope tube The one on my Mak had started to perish and was getting sticky. The inevitable happened - it broke! I've jerry rigged it the best I can. It'll work. The Mak will definitely need collimating; however, that's no big deal. Trying to find a new O-ring, is like searching for chicken's teeth. 🙄 Does anyone know where I can find a replacement O-ring? Many thanks for the help, it's much appreciated. Clear Skies! 🔭😀
