  1. Lately I've been having problems with the fine focusing knob on my Skywatcher Evostar 80ED. The course focus works well enough but the fine focus only works when winding the drawtube out from the scope but slips when turned in the other direction. I've tried all the adjusting screws and dismantled the entire assembly but even when everything is tightened up so much that you can barely turn the thing the fine focus still slips. Any ideas or do I need to get a totally new focuser? Thanks, Harry.

  3. You could also get a telescope with a shorter focal length than the Mak - cheaper by far than a 5D Mk II.
  4. Watched it last night. I remember watching the original series 30 years ago and it was spell binding. Not impressed with the new incarnation. I felt like I was watching a second rate schools broadcast. I was disappointed with the graphics and the presenting style and overall feel of the show. It just seemed very cheap to me and animated historical sequences were very poor. Although it is unlikely I might give it one more chance but expect to have my impression confirmed if I do. VERY disappointed.
  5. Having given up on seeing C/2013 S1 ISON until it rounds the sun I decided last night to try my Astro webcam conversions on the moon which was shining brightly. I'd had a Logitech C500 lying about having won it in a raffle about two years ago and never really had a use for it before. I removed it from it's spherical case and installed it in a Maplins project box complete with 35mm film canister eye piece adapter. Since then it has lain unused until last night. I pointed it at the moon and gave it a three minute run. I have attached the resulting stacked image of Theophilus. Not too bad for a first go, specially considering that it looked so wobbly during recording that I thought there was no way it was going to work. I think the undulations must have been an atrifact of the recording software as they don't look nearly as bad in the recording as they did on the screen.
  6. I was out last night with my new C8 scope to try to find C/2012 S1 but failed miserably. Not quite sure why but between the corrector plate misting up (despite a dew heater), wobbly seeing, possible trees in the way and maybe even me looking in the wrong place it added up to nothing. In the end I took the OTA off the mount and replaced it with my DSLR and 50mm lens to try some wide field shots of Orion, this one was my best. A single 2 minute exposure at 100 ISO.
  7. Welcome, looks like you've got a great location there. I'm envious of your skies! I've been to Telemark a few times. Is your cabin anywhere near Rjukan? Harry
  8. Matt, could I ask what sort of connection exists on the Skwatcher small dovetail where the ballhead is attached? Is it a 1/4" thread? Thanks. Harry.

    Hello.

    Hello all, thought I should introduce myself. My name is Harry, I live in Northern Ireland and I've just bought myself a new 'scope. I bought a Zeiss Telementor 2 about twenty years ago and dabbled a bit with that but it's languished in the attic for years (and I must get around to selling I think) but having heard about Comet Ison a few month ago it reignited my interest in the night sky so I started looking about for a new and better telescope to use to see the comet and thereafter to use for general astronomy and perhaps some astrophotography too. Having long liked the design of the Cassegrain, it being a fairly good all rounder and also compact for the aperture I was looking at getting a Skywatcher Skymax 127 Goto but happened upon a Celestron C8 XLT for what seemed a very good price on Ebay. I came with a CG5 mount, Kson 2" diagonal, an unbranded 32mm eyepiece of unknown design and a 15mm Vixen NPL. I also purchased subsequently the Skywatcher Synscan upgrade for EQ5 which I have successfully installed and had a play with on Tuesday night. I tried a few DSO's on the Guided Tour option but was defeated by light pollution - having set the telescope up in front of the house in the full glare of our street lights for testing. Still it was useful to get the thing up and running and guiding accurately. It also showed me how rusty my knowledge of the stars is when I first looked through the Polar scope and had trouble deciding which one was Polaris!!! Soon got the right one and got it lined up (well, I say "soon", it was't really THAT soon) and viewed a multiple star, the Pleiades, Uranus and the moon. I have yet to try controlling the telescope from Stellarium and I'm also currently trying to build an enclosure for a Logitech C500 webcam that I have lying about. Looking at getting a few new eyepieces also as my current set is far from complete. Thinking of starting with a 25mm Celestron X-Cel or a BST Starguider. Looking forward to participating in SGL Harry
