    Chair for Bino viewing

    Chris Could you give more info on the mount as I am after one at the moment. Many thanks Richard
  2. Just returned from a short break in Prague. We visited the observatory which is open most nights for a couple of hours. It can be reached various ways but the most spectacular is via a funicular railway. As we approached the observatory a shooting star passed overhead, quite stunning. There are 3 domes, 2 of which are open to the public. In the first dome I was able to observe a double star, but with the language differences I wasn't really sure what I was looking at. However from the central dome, it was initially aligned to "epsilon lyra", initially observing it as a double star then at higher magnification the double double and fifth element. If any one ever visits Prague then this is a must. There are some fantastic displays including meteorites, including a sample of one brought back from the moon. The evenings are run by a mix of local amateurs and students from Charles University. It has certainly given me a good introduction to double stars.

    Eyepiece and filter storage

    Ruud, had a quick look at this, very interesting, think I will order some items from here then house them in a "flight case". Thanks very much.

    Eyepiece and filter storage

    Thanks for the quick reply, I'll follow the thread now.
  5. I recently purchased a couple of new eyepieces and I have been searching for some type of container to store them in similar to bolt boxes - that don't seem to be around or I am not looking in the right places. Could also do with giving my filters a new place to be stored. I would like to know how others store theirs.
  6. My 12" dob is about 9 years old and hadn't been cleaned. The mirror was quite grotty, worse than your headlamps get when they have gritted on the motorway! After searching google and youtube at the experiences of others I decided to have a go. Bought BP cotton wool and a gallon of distilled water. Took it apart and got stuck in. To be honest I dont think I noticed any difference. Putting it back together and collimating it from scratch was a bigger challenge. What I did find was that the cheap laser collimator I was using was out of collimation. Once I had collimated my collimator and adjusted the scope things were definately better. Looking at the primary with all its dust probably makes you feel you have to clean it, but if I had known that for me it made no difference, I wouldn't have bothered. Keeping it in adjustment for me is far more beneficial, but these are my own opinions and may not be shared by others. (Many folk are for cleaning the mirrors but many are against it).
  7. I've had great satisfaction from mine, sure you wont be dissappointed. In fact I have only used the 12" for the last year or so.

    Setting circle

    It seems that you all seem sorted. However I have drawn up setting circles for both of my dobs using autocad. They have been drawn anti clockwise as they are mounted on the top plate. With the 8" I plotted it on paper and put sticky back plastic on either side. However this didn't lay too flat and I wasn't really happy with it. I had a rethink for the 12" and had it printed on adhesive plastic/vinyl - the sort you see on the wheel covers of 4x4's. This worked great. If anyone is still after an anticlockwis setting circle I can send a copy as a pdf, dxf or dwg format. The degree divisions could have done with being a little wider, and I will do this or I could probably scale it to other sizes if required.
  9. I find all the posts encouraging so I am going to give it a go. The more I read about it the more I feel I would like to see how I get on then I guess its get hooked and more equipment!
  10. Once again the posts have been very helpfull and encouraging. D4N, I am not exactly sure that I understand about removing one of the excess pieces of plastic but hopefully it will be obvious when I have a look - thanks Richf.
  11. Thats quite encouraging. The next clear night I will spend some time at it. I appreciate your replies as I wasn't sure what I could expect. Rich
  12. I have an Explorer-130P SynScan AZ GOTO which I got initially to learn my way around the heavens. All of my time has been spent visual, I did have a go at converting an Asda web cam when there seemed to be a few posts about this particular web cam but failed miserably. Some time back I obtained a SPC Phillips web cam. Would I be wasting my time trying to get images of the moon, saturn and jupiter? I beleive I would have to use a barlow to acheive the neccessary back focus or can I use some form of extension tube? If anyone has experience or knowledge of this particular scope and imaging I would like to hear your. Rich.

    Zoom eyepiece or 2 eyepieces ?

    Rune thanks for that - sorry for the delay in responding - Rich

    Even lower power EPs - better at 2" ?

    Ben thanks for that Rich

    Even lower power EPs - better at 2" ?

    I have read this topic a few times and find all the posts very informative. I understand now about maximum exit pupil / maximum dilated pupil but how do you measure/determine your maximum dilated pupil. (dont want her anywhere near my eyes with a retractable steel tape).
