  1. I've got the WO EZ Touch and can say it's very nicely engineered and finished. I use it for my WO Zenithstar 105. Haven't got any experience of using it with 2 scopes loaded on it though.
  2. I use Bob's Knobs on my C8 SE and have had no problems - unusually for me as I'm anything but technically minded! I was just having a look at the fitting instructions that come with them, which are quire detailed - it might be worth revisiting them to check you've followed them exactly. For Celestron users you have to " Loosen each collimation screw in sequence by a fraction of a turn until tension is just removed from the screws. Do not remove any of the screws during this process" - and then remove the screws one at a time and replace with a knob, before going on to the next one, etc. So presumably following the instructions is critical - possibly otherwise you might end up with a big variation in tension between different knobs. I had a similar problem with my OMC Mak-Cass, having got the collimation screws all out of kilter and it took a trip back to Orion Optics to identify the problem . Could that be something to do with it? Just a thought. Regards John
  3. The thing I like most about the 8SE is how light it all is - I can carry it in one piece which makes grabbing a break in the clouds more tempting than the prospect of dragging out separate heavy bits of kit. I've found that Bob's Knob's make collimating it very easy. I'm sure you'll enjoy your purchase! Regards John
  4. Hi all,thanks for all these responses, it's reassuring to know that the views I've been getting are pretty par for the course. The seeing in Glasgow is generally poor to awful and I think that is probably the determining factor. Interesting to note the views through a C9.25 aren't any better than I've been seeing. Mars has been pretty elusive but there have been one or two occasions when I've had some good views. And Saturn does tend to be a bit easier. And I'll have a go at using a webcam as suggested by Gaz- something I'd never have thought of! It should do away with the running from one end ot the tube to the other which definintely makes it a very frustrating and annoying experience! Interesting to note the number of good ideas you come across on a forum like this! Thanks again John
  5. Hi Folks I'm wondering if anyone out there can give me any tips on an efficient ( and hopefully easy) way to collimate my Orion Optics 200 Mak- cass. It has a long tube so you can't peer down one end while adjusting the collimating screws ( which are very small grub screws anyway and tricky to adjust). I find the whole process a nightmare, running from one end to the other. And for the avoidance of doubt my significant other does not find the process an interesting distraction! My other problem is detecting whether collimation is out or not- probably sounds dim but I find it difficult to be sure whether the scope is precisely collimated . It all looks ok but I'm wondering whether at the margin it needs a tweak that I'm not seeing - at present for example views of Mars are fairly good (given usually poor seeing) but not great and I wonder if I'm not getting the best out of it because collimation could be a bit better tuned ( the scope is stored outside the house and cool down is not a problem). Any advice and experience gratefully received! Cheers John
  6. I sympathise - I have experienced similar problems. OO have told me it is very sensitive to seeing and collimation . Also, it takes a long time to cool down! I usually use the fan for half an hour or so. I have found collimation very tricky - those small grub screws on the secondary cover are a bit of a nightmare IMO, coupled with the long tube. Collimation really has to be spot on. But when everything is ok you will get some excellent views with it. Barry at OO has told me that in most seeing conditions you're doing well to be able to use a 20mm EP and my best to date has been 15mm on one night with very good seeing ( a very rare occurrence in suburban Glasgow). Generally a 25mm EP works well. It's less picky on the moon and I've had some fantastic views. Very narrow FOV of course and it really is a lunar/planetary scope.
  7. Hi folks I'm looking for a portable battery supply for my vixen sphinx. I've got BTW a Celestron power tank for my Nexstar but the power cord doesn't fit the sphinx. I got the sphinx from Orion Optics who haven't been able to help. Anyone know something suitable ( or an adapter that would let me use the Power tank, though I don't know if it's compatible current wise). Thanks John
  8. Hi all, thanks very much for the warm welcome! And this time, as you'll see, I've made sure the caps lock is off! John
  9. HELLO, MY NAME IS JOHN AND I LIVE IN THE SUBURBS OF CLOUDY (AND WET) GLASGOW. I'VE BEEN INTERESTED IN ASTRONOMY FOR MANY YEARS BUT AM NEITHER VERY KNOWLEDGEABLE NOR SKILLED! I ONLY GET A CHANCE TO OBSERVE OCCASIONALLY DUE TO A COMBINATION OF THE WEATHER, WORK AND OTHER COMMITMENTS. I HAVE AN OMC 200 AND A WO ZENITHSTAR 105 ON A SPHINX MOUNT. WOULD LIKE TO GET AN OBSERVATORY SO I CAN MAKE THE MOST OF THE FEW OBSERVING OPPORTUNITIES THERE ARE - BUT IT WILL HAVE TO WAIT TILL I MOVE HOUSE! I'VE TRIED A LITTLE WEBCAM IMAGING BUT AM A COMPLETE BEGINNER. CAME UPON THIS SITE BY CHANCE, AND I'M LOOKING FORWARD TO LEARNING A LOT!
