  1. Always worth remembering that the likes of Galileo and other iconic astronomers - you know, the ones who discovered the things we look at - used small telescopes with optics so bad even cocacola would use them for the bottoms of their bottles! Your daughter is awesome, as is your scope. I hope you both enjoy it.

  2. Another go at this large but faint target M33. A stack of two 600s subs @ ISO1000, no darks/flats. Camera - Fuji S5 Pro, scope Altair Starwave ED80. From dark sky site in Mid Wales. Dont think the autogiuding was the best as one of the subs had eliptical stars.

  3. Just to add more food for thought, as a general rule of thumb the brightness of an object will decline as you up the magnification. If I up the mag twofold, say, I'm reducing the image brightness by a factor of four. If I keep on doing this eventually details just disappear. On the other hand, increasing the mag does make detail more apparent, so, as you can appreciate, we're now at a trade-off: will increasing magnification gain more detail even though I'm making the object fainter? I've found that playing around with this trade-off - dependent on the evening's seeing (I've found that LP does

  4. If I had been treated like that I would have gone home, put the kettle on, and had a nice brew.......... then, I would have: Called the shop. Explained that I was new to Astronomy and was looking to buy a nice new telescope. I would explain that the shop had been recommended by a friend as being a great place to buy from, but that I needed some help. I would mention one or two (fairly expensive) telescopes that I had been recommended to consider, and ask for their help and advice with "all the other stuff I might need to go with it" At this point you can probably imagine the £££ signs startin

  9. Visit the other shop and just call in to see what they hold, see if they are any better. Could they be worse? If the internet doesn't bother you ring Alan at Sky's the Limit for appropriate bits. When I ordered 2 eyepieces from him he did point out that I was either mad or brave - which was an accurate description of the situation. He was nicely warning me, then I explained the scope(s) and the reason for the eyepieces. Said previously your 114 is bigger then any of the 5 scopes I have. I am sat here trying to work out what the consequences would have been ahd he passed to same comment to anot

  10. Great report. I'd describe the Orion Nebula through my 16" (even at home with bad LP), 13mm Ethos and UHC filter as completely ridiculous. It's the only object that when presenting it to my occasional observing buddy, warranted the use of the word 'behold'.

  11. I don't think so. I would say instead that we seem to agree that the person in the shop was unprofessional, unkind and inconsiderate. Yes indeed, people are who they are.... but shop assistants engaged in serving customers in a rude and unprofessional way most certainly can change their ways. They can realise their mistakes and modify their behaviour (learning) or they can be warned about their behaviour by the shop manager or owner. If the person is the manager or owner then they learn via complaints, poor sales, or by reading forums such as this one. Absolutely! No need to worry abou

  12. When you go into a shop that sells astro gear, you can tell the difference between a sales person and an astronomer. A sales person will try to sell you the biggest and best scope because they are earning commision on every sale. If the sales person is an astronomer themselves, then they will listen to you and your wants/needs and advise on the best way to go. When i bought my first scope, the guy in the shop (who is an astronomer and a friend of Sky at night tv show) took into consideration my disability(wheelchair) and guided me towards a scope that was half the price of the one i had in min

  18. The Eastern Veil is the brightest segment followed by the Western part then the somwhat fainter and less distinct Pickerings Wisp. There is a useful location map on this web page: http://observing.sky...1/NGC_6960.html The star 52 Cygni is bright enough to been seen with the naked eye. Thats where I head for to find the Veil. Use your lowest power eyepiece - it's a huge object as can be seen from that map. Dark skies show it best of course but sometimes you have to make do with what you've got !

  19. I also have this chair and can second everything you say. I would say this is the most useful accessory that I own - being comfortable allows to to spend much longer at the eyepiece and it is when you do that that you really start to see things. It is heavy and sturdy, but as a big chap, I can appreciate that it isn't going to collapse under my weight any time soon! Rich

  22. I would think quite accurate, modern Science can predict from known facts the general movement of the Heavens as we see it from Earth, hence your published star position tables and relative Astronomical data which is updated and republished from time to time John.

  24. Hello Lisa and welcome aboard. When it isn't cloudy I cannot see the Milky Way in Staffordshire (my bit of it anyhow) due to light pollution. You are indeed, fortunate. Don't be shy about posting here. It's easy as you have no idea who you're actually talking to and aside from anything else, everyone is very knowledgeable and very friendly Have you told us what 'scope you have (or have I missed it??) Clear skies !? Scott.

  25. When I was a beginner in astronomy I encountered some outlets where the salesperson's idea of his job was to show how much he knew and how little I knew. Now that I'm not a beginner I still avoid those outlets and I certainly never recommend them, or even mention them, when asked about suppliers. Some vendors just never get hold of the crucial idea that negative comments of any kind just rebound directly onto them. In WIrksworth there was a butcher whose sign insisted that their home cured ham was 'not wet and rubbery.' For me they were just the 'wet and rubbery ham people' and I never went in

  26. I don't think you will find an eyepiece that will get the whole of the Veil complex / M31 and companions in to be honest. My 10" F/4.8 Orion Optics newtonian is the same focal length as your dob and the Nagler 31mm gives me a true field of 2.12 degrees - not wide enough to show the whole of either object and the 31mm Nagler is about as wide as it gets. In my 102mm ED F/6.5 refractor though the same eyepiece shows nearly 4 degrees of sky which is enough to get the whole of the Veil in and most of M31 and companions. I'd not buy a wide angle eyepiece to use in an F/6 scope for £40 to be honest.

  34. If working then realistically observing means Fridays and Saturdays. To me this "seems" obvious but I only know of one club, in a total of 4, that actually has the sense to arrange their observing on this basis. Friend who sails said that astronomy is like sailing, best considered when retired. Earlier nights mean you can do some earlier in the evening, however a large scope and complicated setup tends to work against this. One of the reasons for a small grab and go set up. Which is where a half reasonable 80mm achro of say f/7-f/8 would be a good instrument. A 150 Dobsonian is another small

  35. To move the worm a little away from the driven gear (and thus loosen the worm): Use a 4mm Allen key to loosen a little the 4 nuts securing the worm to the mount. Use a 2.5mm Allen key to turn the adjusting setscrew clockwise a fraction of a turn (yes, tighten the setscrew to loosen the worm). Tighten the screws either side of the setscrew first, then tighten the other pair of screws. If the worm was too tight it will now be easier to turn. Check the play in the gear. This is one adjustment that is critical - adjust again ( and again) if necessary to get a worm that you can easily turn with

  36. I'm a chef. I get up at 7am, and finish at around 22:30. It's very rare i get to observe anymore. I usually get a break in the afternoon, but that's usually just enough to eat and smoke. Sometimes i'l do some solar observing. Waiting to hear back about an interview i had last week for a software testing position. 37 hours a week and flexitime.... No evenings, no weekends, no stinking like a deep fryer, no moody girlfriend, and definitely no minimum wage. Fingers crossed!

  37. M32 is close to M31 but clear of the galactic "halo" from the larger galaxy. It resembles a brightish fuzzy star. M110 is much fainter and a little further from M31, on the other side from M32. It's easy to miss in less than dark skies.

  39. That's a very nice way of doing it. When I get to do mine I intend to use a 150x150 square box section with a flat plate welded to the top. The central mounting bolt will be accessed through a hole cut in the side. This, for me, is the simplest solution. No machining, no tight tolerances and easy to fab up. I don't subscribe to the whole "wobbly bolt" thing though. I have done the calculations on the bending moment required to deflect a 16mm bolt, and it is a lot (IIRC, something like a 50Kg end load at 90 degrees to the axis of a mild steel bar 125mm long deflects the bar by half the width of

  41. I think the idea was based on a scene from a favourite film of mine....... can you guess which one? Shop assistant: Hello, can I help you? Vivian: I was in here yesterday, you wouldn't wait on me. Shop assistant: Oh. Vivian: You people work on commission, right? Shop assistant: Yeah. Vivian: Big mistake. Big. Huge. I have to go shopping now. There were so many great lines in that film!

  42. I'm a lifelong continental cycle touring camper so I find this tiny caravan enormous. With its awning up it is really a spacious place to live. (The awning can be fully encolsed if you like.) Alas production of the tiny Puck model has stopped and they are going up in value but this cost about £4.5K here in France. I tow it with our turbo diesel Panda, incredibly easily, an still get nearly 60mpg. Hey, we blow off Limmos towing giant caravans!! Motorway is free, too. Serioulsy, it would be a great aid to mobile astronomy. Eriba Puck is the make and model. We're chuffed with ours, though we use

  45. For DSO photography you really want: A short focal length ED refractor A motorised, sturdy EQ mount GOTO is advisable An ED80 on an HEQ5 pro would be ideal. You can just about get away with an EQ5.

  46. I,v finally finished my Tal. i,m pleased with its performance and its lighter and more convenient to use as a grab it and go. Plus it dosnt bother my other half as much when it lives in our lounge. I will drag out the 8inch newt for DSOs etc. i made a spongy hat for the rigel, even though it dosnt seem to suffer as much from dew as my telrad on the newt. The scubapro is a stretchy band for sorting the balance after re-aligning the tube during the night for best positioning. The good thing with a stretchy band i find ,is you can move it in relation to the changing weight of the ota. The solid d
