  1. hehehe Now I know Mrs Black Knight would like it too!
  2. I love the decorative stones around the pier. I think even Mrs Black Knight would approve of that!
  3. Hi and welcome from a fellow 200p owner
  4. Ahhh... I think I recognize this problem
  5. You could try the Field of View calculator here Sky at Night Magazine - the world's first astronomy magazine and cd package, it might give you an idea what to expect. There is a standalone link somewhere for this tool but I can never find it
  6. Have to say I like the sound of this kind of in-depth testing. But it's probably not what you'd expect to find in SatN. Come on AN, you know you want to!
  7. I'll bite I think it depends largely on what sort of astronomer you are. Personally I think SatN magazine caters quite well to new astronomers or casual observers, but lacks a lot of the in-depth or technical stuff more experienced observers may be after. I love their Night Sky guide though. Astronomy Now has a little more 'meat', if you like. Just my opinion though ... /dons flameproof suit
  8. Interesting pics . So are you using 2 bolts to attach the guidescope adapter to the dovetail? That would seem much better.
  9. I live on the edge of West Swindon, but I do my stargazing from the back garden as it is difficult for me to get out to any dark sites. There is a fair bit of light pollution for me facing south, but otherwise it's not too bad. / is no help at all, sorry
  10. I was fixated on thinking about DSO stuff, as that's what I do use mine for!
  11. I don't know about the Nikon D200, but many DSLR users seem happy with around 800 ISO. That's what I tend to use with my Canon. As for exposure times, it's all down to how stable your mount is, how good your polar alignment is, and whether or not you are guiding. I've only recently managed to get up to 60 second exposures without star trailing, but many people can get up to 2 mins without a problem (unguided). Obviously if you are guiding you can go for longer exposures. Is your 6SE on an altaz mount or an EQ mount? Altaz mounts aren't ideal for long exposure photography. For the planets and the moon many people use simple webcams as opposed to a dedicated camera. Some of the results are absolutley stunning. My own attempts less so
  12. I have been wondering about these too. The main advantage for me would be the ease of setting up and taking down compared to a traditional piggyback arrangement. So for me it would be down to something like this or a standard side-by-side bar. But the mounting does concern me though. If I understand it correctly it is mounted on the main OTA tube ring using a single camera-type stud which, well, just doesn't seem very secure. So I'd be interested in hearing about any real-world experience others have had with this.
  13. OK, flexure, focusing, and loose USB cable. Got it . For a relatively small outlay it might be worth a try. Thanks guys
  14. Following a suggestion by Glider, I'm toying with the idea of trying out my standard Skywatcher 9x50 finderscope as a guidescope on my existing mount, using the QHY5 and the adapter from Modern Astronomy (Accessories @ Modern Astronomy). Are there any pitfalls, problems or drawbacks you guys may have run into while using a finderguider? Forewarned is forearmed, and all that . Thanks
  15. Aha! So does that mean if you have several bases you can easily move the RDF between scopes?
  16. Just a quick question. Am I right in thinking that the base of the Rigel RDF is attached to the OTA using adhesive tape? Or have I got the wrong end of the stick?
  17. I did look briefly at doing a finderguider a little while ago. Definitely worth a thought. I think I'll have another look ....
  18. Jim, took me a while to figure out just what was going on your pictures! Very impressive looking though
  19. Wow, thanks Stephen, you've coverred all my questions
  20. First of all I apologise for the long post, and long list of questions . I'm looking to upgrade my setup to allow me to do guided photography, initially with my 200p newt and DSLR, and later on adding an ED80 for more wide field work. I'm planning on upgrading my mount to either an HEQ5 or an NEQ6 and using an ST80 as a guidescope. My questions are: 1. Should I mount to guidescope ontop of the newt or side by side? Which is the best way to go? 2. Should the guidescope be mounted with normal tuberings or guidescope rings? I've always assumed that it should be with guidescope rings, but I'm sure I read on SGL recently that normal tube rings would be okay (although I can't find that thread now ). 3. Although I hope to be able to buy a cheapish guide camera at some point, I know PHD says you can use a webcam (I have the NexImage) for guiding. Would this work OK on an ST80? Or should I be budgeting for a guide camera straight off? 4. I know with a guide camera you can use the onboard ST4 port. But assuming I can use the NexImage webcam on an ST80 together with PHD for guiding, how do I actually connect up the laptop to the mount i.e. what sort of cable do I need? Any help you could give me would be very much appreciated, thanks,
  21. Nice I'm always a sucker for images of this pair Which scope did you use, and was this taken with your Canon?
  22. I love that image. I'm considering the 314L+ as a future puchase as well, so I was very interested to see what it could do
