  1. I would really like that but the website is clearly German. I don't feel very comfortable ordering anything from a website I can't read. It seems to be well over £1000 in England Any further ideas??? Clicking on the Union Jack on the webpage linked above seems a good idea;)
  2. Look at the Rigel, as with the Telrad, ggod though they are, you'll need a lot of counterbalance weight at the mirror end. Rigel only weighs about an ounce or so.
  3. Mine had a straight through finder. I replaced it with a 90deg, for comfort and added a Rigel, which was then used for 95% of the time. No balance problems with the Rigel; it weighs next to nothing.
  4. Go for the Dob and give yourself a year or so to learn the sky and about scopes in general. Then decide which route you want to go down. You may well stay with the Dob, you may not. It would be a satisfying instrument for years and aperture fever would not rear it's head for a long time, if ever! Regardless, the Dob would be able to be easily sold on for a good proportion of it's new price, after you have decided what you really want to do. Astronomy can be very expensive for those in a hurry"
  5. Forget the GoTo and put the cash saved into a bigger Dob and see a lot more! If you want to stay with your GoTo, take the 130 and see a bit more. Aperture rules!
  6. Apologies if it's been shut down, but I guess it's also a timely reminder of what's out there. A few years ago, my other half "won" a Mercedes. I came into the house to "Shush, I'm on the phone" and pointing to a card that had come through the door. A quick read and the phone was back on the hook, but not before it had cost us £10 or so!!!
  7. Mods, fell free to move this someplace if you wish. It is a heads up, but not about astronomy. Postal Scam: Can you circulate this around especially as Xmas is fast approaching - it has been confirmed by Royal Mail. The Trading Standards Office are making people aware of the following scam: A card is posted through your door from a company called PDS (Parcel Delivery Service) suggesting that they were unable to deliver a parcel and that you need to contact the m on 0906 6611911 (a Premium rate number). DO NOT call this number, as this is a mail scam originating from Belize . If you call the number and you start to hear a recorded message you will already have been billed £315 for the phone call. If you do receive a card with these details, then please contact Royal Mail Fraud on 020 7239 6655.
  8. and Lidl and possibly Aldi also do them a couple of times a year for £15 or so. £90!!!!!!!! someone is having a larf!
  9. Any "real" automotive paint supplier (as opposed to Halfrauds) will have sample books covering every car on the market and the recipes for the mixes. Take the finder and work your way through the books. A lot of places will put your specially mixed paint into an aerosol if you want.
  10. Bought an 8" Skywatcher Dob from them in 2004. Ordered on the net Sunday evening and it arrived Wednesday morning. With the Euro/£ exchange rate at the time, the scope itself was around £80 cheaper and the shipping was cheaper than UK inland IIRC.
  11. The finance is more than there, so why not go for an 8" Dobsonian, Skywatcher or similar? It will be easier to use and you will see far more. If you start with a 5" you will be wanting more aperture in a matter of months. A year or two with an 8" and then you may decide you want either more of it, or a smaller grab & go, but for starters, an 8" Dob is almost ideal.
  12. A lot of people in a lot of hobbies have little or no technical and manual skills, but they do have chequebooks! Choose any hobby and you will find decent economical main equipment and expensive "tackle tart" main equipment but the bits and pieces will always be overpriced for what they are!!
  13. Check this one out: GSO Dobson Teleskop - 300/1500mm And here's a test of the Revelation version (made by GSO). http://stargazerslounge.com/member-equipment-reviews/84376-revelation-12-dobsonian-4.html Posts 91 & 93. Teleskop Service are good to deal with.
  14. For children, or even an adult beginner, I'd suggest forgetting the equatorial mount and go for a Dobsonian, as it's far easier and more intuitive to use. My suggestion would be: Sky Watcher Heritage 130P FlexTube™ 130mm (5.1") f/650 Parabolic Dobsonian Telescope I bought one as a grab & go and am quite impressed with it. My first scope was a Celestron 114 on an EQ and though the scope was fine as a starter, the mount was a hassle. A beginner (and many non beginners) want to jump all over the sky and with an EQ mount, you are frequently having to turn the tube in it's mounting rings to look through the eyepiece. If you could afford the cash & space for a bigger Dob, 6" or 8", so much the better, but the 130 will give plenty of satisfying observing.
  15. Part of the improvement with the masked 16" will be due to the lack of obstruction, but also, (I assume), the masked aperture will not include the edge of the mirror, which is always the "dodgy" part when it comes to figuring. Humps or hollows in the centre are usually in the shadow of the secondary, so can be ignored.
  16. Flavour of the month? A bit expensive for a 5" scope too! How long before the owners get fed up and go for an 8 or 10" Dob I wonder?
  17. No wonder I couldn't always get my head around my ETX. I thought Daylight saving was winter time, ie. lighter mornings!!!
  18. Remove the whole spider and secondary mirror assembly, so you can get a good grip on the hub and try again. Be very careful not to touch the surface of the mirror. If still no movement, don't insist. Put a DROP of WD40 on all the threads and leave it a few hours, then try again. Once you have loosened the screws, remove them one by one and put a smear of grease on the threads, before re-assembling.
  19. I can understand the appeal of laser collimators in this hi-tech age, but is there not at least a bit of trying to re-invent the wheel?
  20. Unless the standard eyepieces are giving dreadful views, why not save the pennies for a bigger scope. You'll want one soon enough! Nothing wrong with generic Plossls for everyday (night?) viewing, if you must upgrade. Wait for your "long time keeper" scope before you go for the hand grenades! A 2x Barlow will give you a choice of magnifications.
  21. You can expect to have an urge, very soon, for more aperture. This is normal! Go for at least 6", 8" if you can afford/have storage etc. Dobsonian is easier to use than EQ.
  22. Had a 200p Dob for five years or so; excellent 'scope. Constantly getting compliments for the quality of the images, from owners of 8" SCTs!
  23. You could ask Northek to elaborate. They appear to be above the run-of -the-mill commercial market.
