  1. Sorry, I typed that wrong, it should have been FW. "It was my FW that was offsetting the balance".
  2. Hi guys, I have used the procedure for balancing my side by side set up as explained by Mark Crossley on his website at http://www.wilmslowastro.com/tips/g11gemini.htm#balancing It is excellent, well explained and has never failed me. Just follow it to the letter and make sure that you do not have any loose cables wafting in the wind. P.S Could you remind me what FS stands for, probaly obvious but I am racking my ageing brain with no result :-) Regards from Dave.
  3. I have not watched this, as yet, but it may help. https://www.youtube.com/watch?v=nOqY49FkomM Regards from Dave G.
  4. Hi Mike, what happens if you press ENTER a couple of times following the ESCAPE key press? I am trying to remember without mine in front of me. I tend to fly through it on 'autopilot'.
  5. The nucleus has gone and we are seeing the reminents of cometary debris that are continuing in orbit.
  6. Latest images showing something has survived, fragments + tail. Still worth monitoring.
  7. Guy where in Liverpool are you based? I am near to Alder Hey Hospital and a member of the Liverpool A.S. Have a think about coming along to our observatory at Cronton. We can have a good chat about web cams, telescopes and perhaps give you the chance to try out a couple of scopes before spending your cash :-)
  8. Hi Guy, welcome to the group. What 'scope have you decided on? Regards from Dave (of Liverpool).
  9. How facinating, cloud movement it is then.
  10. Is it cloud movement or planetary rotation over two hours! Excellent image whichever and certainly worth following up. Regards from Dave.
  11. Would the images have to be resized to match each other due to different focal lengths and resulting image size?
  12. Do you mean that you are struggling with the concept of Altitude and Azimuth or actually finding them in the telescope? Where about in the North West are you based?
  13. The monthly meetings are from September to May but the weekly meetings are open throughout the year from 19:00 onwards. Last Wednesday, using the 12" Meade SCT, was great as I got to show a couple of beginners Venus, Spica and Saturn................oh yeah and the Sun was still above the horizion. And afterwards showed a couple of double stars such as Albireo showing the lovely contrast in colours blue and golden Yellow.
  14. Thanks Callum, I will be attending with several members of the Liverpool A.S. I should be sitting at a desk somewhere answering questions on astronomical matters.
  15. Hi Jay and welcome to the group. Lots of info here and plenty of friendly advice. I do reccomend that you come along to our observatory at Cronton, just outside of Liverpool, were you will find like minded astronomers to chat to. We are open every Wednesday evening from 19:00 regardless of the weather. Details can be found on our website: http://liverpoolas.o...eekly-meetings/ Ask for Brendan (Oservatory Director) or myself, Dave Galvin. I look forward to meeting up. Regards from Dave.
  16. I am doing the same mod with the Vixen 80M and will purchase my next piece as reccomended by Pete Drew. http://www.thorlabs.co.uk/thorProduct.cfm?partNumber=LMR75/M I strongly recommend that all potentential pst 'modders' follow the words and advice of Merlin66 (Ken) and Peter Drew and you will find the mod not only easier but also safe. Thanks for all your advice Ken and Pete. Merlin66
  17. Seen over Birmingham and the green colour is usually associated with oxygen. If you observed this and are on Twitter then please report your observation to: David Clapham @DClaphamFRAS
  18. It may be due to using 'multipoint' option which can course this tile effect. Chech the Registax page for ideas: http://www.astronomie.be/registax/5_1features-3.html I recall altering the 'feather' option to get around the problem.
  19. Your set up must be balanced in three directions in order to bring the centre of gravity to the intersection of the R.A and Dec axis. If you do not do this then the balance will shift as you move the scope around the sky. I have used the method as explained by Mark Crossley on his Wimslow Astro website and it works for me. Scrol down to 'Balancing a side-by-side setup', give it a go and I am sure that you will improve your balancing. http://www.wilmslowastro.com/tips/g11gemini.htm#balancing
  20. Sounds like the green eyed monsters are out and about again. :-) Several of us would have loved to have stayed and observed but due to the programme being live it meant that security on the site was heightened due to the possible attempt of demonstrators etc. Besides it was alot warmer in the studio and I managed to blag a doughnut.
