  1. Thanks guys. Yes interesting indeed. I will be questioning my children in the morning as chewing gum does not make its own way in. I was leaning towards warm water and trying to pick it off with cotton wool to protect the surface of the mirror. Would you leave it in the cell or remove it? Thanks again
  2. Good evening. I am after a bit of advice for cleaning my 10" primary mirror. It has been a while since i have used my scope so I took it out this afternoon to collimate it and noticed some items sitting on my mirror. I tipped it up and out dropped a couple of very small children's toys. I also noticed a couple of blue marks on the mirror so I popped it out and it turns out to be (or at least it smells like it) chewing gum. Each piece is about 3-4mm in size. I have read up on general cleaning of the mirror but not sure about the gum. Any help would be greatly appreciated. Many thanks Marc
  3. That is awesome. My best effort with my 1100d below. The detail you got is great. Thanks for posting.
  4. Good detail for not great seeing. Liking the wide angle.
  5. Thanks for clarifying. I am going down the finder guider route so will explore the use of rings instead of the bracket. Many thanks.
  6. Great idea. What are the advantages of using rings as opposed to the standard finder bracket?
  7. Evening all. I am in the process of building my own arduino dc focuser. I will be using it to drive my Skywatcher auto focuser which has a RJ11 connection. I am planning on connecting a RJ11 socket from my driver board but am not sure how to ascertain which of the RJ11 pins should be wired. If anyone could pass on any pearls of wisdom that would be great. Many thanks Marc
  8. Thanks for all the replies folks. That's enabled me to order nearly everything I need just a couple of bits left to order now. Kind regards Marc

  10. Ill check them out. Many thanks
  11. Good evening. I am in the process of building an arduino dc focuser and am slowly ordering the necessary parts. Is it me or is there a shortage of electrical suppliers in the uk that sell the smaller circuit components. Does anyone know of anywhere in the uk that stocks it before I buy internationally. Many thanks Marc
