  1. P.S. The 'short Newtonian' doesn't work either. The control cables still end up in odd positions. I think that the design of telescope that you want should come first and worry about the controls afterwards. Maybe some of those 'helping hand' tools for people who can't bend down might help? Only kidding! I like the sound of your telescope, by the way. A 90mm sounds big enough and the F10 means you can use longer focal length eyepieces to get the best out of it. Happy stargazing!
  2. Hi, I now have an EQ5 mount with push-on knobs. This was one of the best things about the new set-up. I know exactly where you are coming from with the control problem...my arms aren't like a gibbon's either and I needed them for my EQ2 mount with control cables. It didn't matter where I put them, there were always times that I just couldn't reach. I'm trying to imagine the set-up that you have but i think the push-on knobs must work better. If you can reach around the mount from your viewing position, you should be able to turn them. Let us know what you decide!
  3. Hi, This bad weather has left my brain rotting. I decided in an idle moment to design a stand for the shorter astronomer. All sorts of ideas started popping into my head, the favourite one being a telescopic stand that can be pneumatically raised and lowered. This idea seems to be both feasible and practical to achieve. I have almost got it drawn up on CAD, sourced suitable materials and ironed out the little niggly bits of the design. The idea is simple (Putting it into practice required a bit of thought). Once the stand and scope are set up and polar aligned, the stand itself can telescope vertically by around +/- 100mm. In doing so, slackening band clamps and spinning a big Newt to get the eyepiece at a comfortable height is a thing of the past. It also means that if my daughter comes out for a look, I won't need to do the 'balancing her on a stool in the dark' performance. Also, if I want to raise the scope, I won't have to mess around lifting tripod legs and possibly disturbing polar alignment, which will remain beautifully unaltered. It will also be lighter than my Skywatcher tripod and will not have any angled legs for the scope to bang into, enabling viewing of overhead objects without the need to lift and turn the whole caboodle. The scope can spin 360 degrees while viewing over head without catching on anything. It's just to pass the time but the more I think about it, the better the idea seems to be. What do you think and how have you been whiling away the cloudy nights?
  4. Hi, I saw a forecast last week saying that we were in for a cold and frosty snap. My heart leapt and I ordered two Planetary II eyepieces, 3.2mm and 2.5mm. The deal was that if they were not any good for my scope, I could return them in two weeks. The cold snap sort of came, along with skies that only cleared during the day and promptly got all misty and cloudy at night. Only once did I get a few minutes when I got as far as using my 25mm and 5mm and for a few seconds with the new eyepieces. The clarity was not good, but it also wasn't with the 5mm BST which I know performs brilliantly, given good viewing. Tonight I got the scope set up and targeted Jupiter in the twilit sky. I didn't have a great deal of hope because there was a penumbra around the planet even to the naked eye. Sure enough, as it started to get dark, the clouds rolled in and I didn't even get anything other than the 25mm out of the box. Doh! I am faced with the prospect of returning something I haven't even been able to try out, or keeping them, untested and hoping. Maybe I'll see if Alan at Sky's the limit will let me hold onto them for a while longer...it's not as if they're getting damaged wrapped up all cosy in their boxes in the living room!
  5. I have the BST starguiders which I bought for my Skywatcher 130M. I now have the 200P and they work just as well in that. The parfocal aspect is a good one, whichever EPs you ultimately go for. Being able to swap from a 25mm to a 5mm without the need to re-focus is a great boon, especially if your eyes are like mine and it's all a bit of hard work! I have to add that with the Starguider 5mm in the 200P, I saw Ganymede's shadow crossing Jupiter perfectly a few weeks ago...they can't be that bad.
  6. Thanks folks. Sorry i took so long to get back to you...I wasn't stargazing, that's for sure. It's been so flipping cloudy. Maybe i ought to consider it, then. The main thing at the moment is that I don't seem to have messed things up. The other problem is that I can't get a few minutes of clear sky to find out!
  7. Hi, I got a 130p and it never needed alignment. I transported a Skywatcher 200P F5 over our marvellous pot-hole ridden roads and it needed to be adjusted as soon as I got it home! I didn't have any fancy tools. Lacking this I pressed ahead with my little collimation cap. I followed what i thought were the instructions and started with the secondary. Since all the main circles looked concentric, but I couldn't see one of the clips at all, I tweaked a couple of the three screws in the secondary until I could see them all about the same. Then I adjusted the spider to line up with the very centre circle by twiddling the primary adjusters. After going the wrong way once, it was soon lined up. I have attached a picture of what the result was. I am a bit concerned about the fact that the first black ring is offset when everything else is lined up. Also, I can't see the mirror holders at all with the focuser pulled back so that the drawtube is clear of the image. Is this normal? I tried the scope out on a distant chimney (1/2 a mile or so) and it seemed sharp and clear, but I'm not sure if this was a good enough test. I could see the steel boltheads clearly enough. If it stays clear tonight I'll find out, but I'd rather it was right before then. rather stupidly, I didn't look at the same target before I started. If I could have seen an improvement, I guess I'd have my answers. If what I've done is right, is visual collimation good enough, or do you really need a Cheshire?
  8. You don't say where you are pointing the scope. If you are aiming it over your house, for example, that can make a huge difference because of the 'heat haze' rising from the walls and roof. I noticed last night that I saw the shadow of Ganymede transiting Jupiter perfectly earlier on but when I had to aim over the house it simply disappeared. Is this a possibility? Also, seeing conditions are affected not only by the sky but where you put the scope. It's better in winter with the scope over flags or concrete but it's still better if you set up on grass.
  9. Hi, getting off the subject a bit but I could see the three stars in line just before it got misty overhead. Now I know exactly where to look! Back to the original post, I fully sympathise with the kids in bed bit...I'm, a single parent and have exactly the same problem! Could you take them on an exciting camping trip? It would get around the light pollution problem and they may even enjoy it, depending on their ages. My daughter was dancing around the table in the living room after seeing the Ganymede transit last night. She's nine, though.
  10. You may be aware that I've got a new (used) scope, since I was banging on about it last night! I'd just like to add that for all the extra 70mm of aperture is a big improvement (how could it not be?) but after 4 hours of freezing myself to the point I thought I was going to have to hibernate, it was not the most noticeable benefit. That came from the mount, EQ5 as opposed to EQ2. I could locate my targets faster, I could focus on them quicker and it was not a case of needing six foot arms to view while adjusting RA. There was not the judder if I so much as blinked an eyelash against the eyecup. I did not run out of adjustment on declination. The mount made the whole experience so much more enjoyable. I wonder how many people have been put off astronomy by hours of groping blindly for a flex-cable that they know is there somewhere, or having to watch a blurred planet sailing several times across their field of view before they finally get it focused?
  11. It's really beautiful. I'm an engineer and I just love the sight of a well made telescope...sad, eh? All the best with your new baby.
  12. Sorry, I've just had another thought. I think your two choices of size are fine, as I said before. I'd like to give you a practical example, since you are interested in planetary observation... ...it comes down to the point about resolution again. I have a 130 and a 200 Newtonian (on EQ mounts, not Dobsonian but that is irrelevant to the views). With the 130, I could never see the shadow of Jupiter's moons on the planet because it could not resolve that level of detail. Lastnight, using the 200, I saw a beautiful crisp shadow of Ganymede crossing the face of the planet...another argument in favour of the 200! you may make it out with the 150 on a good night but you'd be assured of seeing it with the 200.
  13. I agree to a point. Since the options are 150 F8 and 200 F6, the eyepiece focal length is the same for a given magnification, so the extra expense of tolerances on smaller EPs does not apply. Both should perform well. The 200 will get more detailed images because it can resolve more detail. It will be a bit more fussy about collimation but it is not a very fast scope, so it shouldn't be too bad. I'd go for the 200 if i could afford it and handle it...these things are big! Also, you don't say which brand. There's a big variation in quality out there. The size doesn't matter if the optics aren't any good.

    hi

    Hi. You sound much more sensible than I am! Used will get you something better for your money, if you trust the seller. All I'd say at this point is that I got a 130 Newtonian and very quickly wanted a 200. Get the biggest aperture you can afford but bear in mind that you'll probably end up buying extra eyepieces, like most of us do when we find out how poor the original supplied items are. From this point of view, second hand could be even more of a bargain if someone is selling good quality eyepieces and other goodies with the scope.
  15. Hi, The wobble will never really go away and it's a nuisance but you do get used to it. The flexing is not just from the tripod, it comes from the mount, too. I know because I've got a 130 F7, which is even worse because of the extra tube length. The supplied Eps are not bad, but the Barlow is not great, if it's the same one I got with my scope. You should comfortably manage x200 with that scope. I bought BST starguiders for my own Explorer 130 and was not at all disappointed. They are not too dear and will give you much better brightness and clarity. A 5mm, 13mm and 25mm will give you a good range. To get the x200, you'd need 3.2mm. I can't advise on these as I don't yet have one! At x130 (x2 Barlow + 10mm on an F5 130 scope), you should have got clear images, so long as it was not misty, loads of light pollution etc. If you think the sky was not nice and black, try the standard issue on a clearer night before you splash out loads of dosh on nice new eyepieces!
  16. Yes, I agree. I'm pleased you are as secretive as I am. Those people who install 15 megawatt 'security' lights that turn on when so much as a slug creeps past need to be dealt with, too. Maybe you could design a special hat for the lady concerned, which has a low-powered red light dangling in front of her eyes, so that she is reassured and does not feel the need to flood the entire country with blinding light?
  17. Nice one. Except that it's a member of SGL and he wouldn't believe me! Mind you, I also don't want to upset him because he is in with my plan of inserting valves and circuit-breakers in the gas & electricity supply lines, so that we can turn off everybody's heating and lighting a few days before clear skies. This way we can get good seeing without light pollution or the nasty disturbances caused by heat rising from those stupid houses everyone keeps building. This plan may not be entirely legal, so I'd ask you to keep it to yourself.
  18. Darn it! So close and yet so far. I nearly got it but after I went back out the sky was getting hazy. I cursed and stomped around a bit but had to call it a day. At least i know where to look next time. Thanks for this. I'd dearly love to see a supernova. When I finally had to call it a day, i was wondering why my favourite TV programmes weren't on and also why my fingers were painful...then I looked at the clock and realised I'd been out there for four hours! I've heard that we are going to get a cold snap. Great! I hate the gas bills but at least I may get to see more.
  19. Okay, here's where I've got. I am looking from the bottom left star of the big dipper through the top right about the same distance but to me, a bit to the north. I can see two galaxies. One is face on and fairly circular, the other (more northern) one is a wild streak across the sky. If this is where the supernova is, I can't get it clearly. I tried x40 and x 65 with BST starguiders. If the northerly one is a galaxy, it seems to streak out in a strange fashion. You're the man. What am I looking at? I think i need to tweak the collimation on my scope a bit, by the way.
  20. If only. I'm so flighty, I can't do the serious astronomy stuff. I just flit about the sky in a random fashion. I could have seen loads of galaxies but i wouldn't know what they were. Mind you, I really would like to look at a supernova! M82? I'll look it up. Thanks.
  21. Oh, dear, It just seems to keep coming at me, tonight and I still haven't even vaguely tried to align my (new to me) scope. Consequently, when I tried to look for the Orion nebula, I had to hump the scope up the slope of the garden, roughly point it at the pole star and start looking South of Orion's belt. My luck is really in, tonight. The spotter scope showed a blur, so I took a peek. What I saw looked to me like a seagull with a single bright star in the body and a row of three stars in one wing, if you get what I mean. Is this the Orion Nebula? I was only using a 25mm BST starguider, so magnification would be about x40. The 'seagull' filled a good part of the field of view. One of these days, I won't be so impetuous and I'll actually know what I'm looking at! anyway, I must dash. I want to look at the Pleiades.
  22. I've read reviews by people who claim to have seen the nebulosity with much smaller scopes. Personally, I'm beginning to think that they have vivid imaginations. I'm going to take a peek shortly, once the pain eases off in my fingertips. I Don't think I'll see any gas cloud with my 200P but it won't stop me basking in the cluster's (literally) reflected glory.
  23. Sorry, mate, I didn't see the post that you made. I am really excited. All the best to you and your family, cats, chinchilla, rats and fish. My daughter had a whale of a time looking at all of your menagerie while we were doing the 'boring' stuff! You made her day. i can only wish you and your pets etc, the very best. It was lovely to meet you all. I talked about it in the car on the way back (when I could get a word in, edgeways) and the thing that struck me was that you are the very sort of people that I am comfortable with, so much so that I probably talked incessantly. Thanks for the scope and your kind help. Thanks also for a great day. Mark
  24. Posting my own reply...dumb, I know but I can't help it. A website said that the transit ended at 21:30. It ended before that, unless I'm very much mistaken. I looked at 21:10 and couldn't see the shadow. Ganymede was much further out by then. (I'm still not sure if it was Ganymede, I haven't checked yet). It all makes me wonder at just how lucky I've been. My daughter and I danced a jig around her desk in the middle of the living-room to celebrate. If you can imagine a pretty girl with long, flowing locks and hazel-brown eyes, together with a short man with an enormous dark beard, dreadlocks down the middle of his back, bouncing gaily and with wide dark brown eyes, that was us. I explained to my 9 year old (when I was lucid enough to do so), that she was very lucky to see a transit of a moon so clearly at over 460 million miles and she was suitably awestricken. Lovely. How fortunate are we to be able to witness such sights?
  25. Hi, I have a 130 F& Skywatcher explorer but today, amidst lashing rain and wind I collected a Skywatcher explorer 200P from a member of SGL. Whilst making curry for myself and my daughter the skies cleared. Curry was put on hold and the new 'monster' was taken out. Barely allowing it to cool, I stuck in a BST starguider 25mm and locked onto Jupiter. I yelled at my daughter to fetch the 5mm EP and slotted that in. I focused and couldn't believe what I was seeing. I had no idea that Ganymede was transiting. With the old scope, I could not have resolved the shadow. With this one at x200, there it was...a plain black circle about a fifth of the way across Jupiter's disc. Ganymede itself was close to the disc at the time. My daughter saw it and I had to phone nephilim in my excitement, to tell him. That is just the most marvellous confirmation of the new scope's ability and how lucky am I for the sky to clear and let me watch it. I'm going back out for another peek. See you shortly! P.S. I'm so excited I'm only guessing that it's Ganymede. You have my apologies if I'm wrong!
