  1. Help! Am I being stupid :x or am I right in thinking that if I put my Dob on a wedge with the same angle as my latitude I can use it for basic imaging by using the Az rotation of the base to follow my target e.g. Saturn :saturn: ? Brian.
  2. Congratulation to your family. I like the tangerine coloured suit - a Blackpool supporter me thinks ? Brian (Nr Blackpool)
  3. Fantastic. Great picture - it makes me feel all broody again (don't tell the wife though!) Brian.
  4. CONGRATULATIONS Steve & the family. As a father of two (aged 3 and 1) I know how tough it is - best of luck!!! Take lots of piccys and enjoy it whilst they are young - soon they'll be teenagers - then the fun will really start..... Brian.
  5. Well done! It's a small World (when you look at DSOs) but I too was having only my 2nd hunt from DSOs last night and I too found M57 and M13 at 11.20 and 11.30 respectively. I'm trying for the Leo triplets tonight - see you there !!!!! Brian.
  6. Philip, So far all I have is the Digital Angle Gauge (for Alt reading) £25 from ebay. I use Stellarium to give me the Alt of an object and then basically scan left and right to find a recognisable group of stars, then hop to the object I am looking for. The addition of an angle scale on the base will allow me to use the Az reading on Stellaium to get much closer - if not spot on with a 30mm eyepiece. I am trying to find somewhere that will print and laminate a 20" scale for me. Photo of Angle gauge attached. I basically used a spirit level to set it to zero, it then sits magnetically on my scope and shouldn't need resetting until I have to replace the battery. The only slight problem as mentioned is that it is difficult to read in the dark so I am going to rig up a mini red LED type torch thingymajigwatsit to help read it and the Az scale. The Cloudy Nights forum has loads of pictures of what people have done. Brian.
  7. Count me in, I design websites (in my spare? time) so may be able to help. Brian.
  8. Red Torch or LEDs sound good. As I said I've only got the Alt scale working with my meter and I managed to find M57 - The Ring Nebula and M13 in Hercules in about 5 minutes by setting the Alt scale and a rough Az scale then sweeping. Brian.
  9. Philip, Have you looked at creating a push-to system for your Dob? Check out this link http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/937949/page/0/view/collapsed/sb/5/o/all/fpart/1/vc/1 It looks fairly easy if you can find somewhere to print the circle and laminate it - I'm still struggling. I bought the digital meter for £25 off ebay. Brian.
  10. Quick - lets build some more Nuclear Power Stations.................
  11. I saw it!!!!! It was great, I was just scanning around the edge of the moon and suddenly Saturn appeared. Managed to watch it for about 10 minutes before the clouds rolled in. Here's a piccy. It was taken with a Panasonic DMC-FZ5 digital camera held up to the eyepiece. I have great trouble trying to get the camera to focus on what I want to take a photo of - it's auto focus. I have loads of photos of my telescope mirror and not many of the moon and planets. You can see from the photo a large circle around the picture - is this a reflection of my mirror? Any help appreciated. And another Brian.
  12. Sorry, I'm a code freak - I don't use any tools!!!!! Sorry I didn't put the link in 1st time - amended now http://www.blackettworld.com/bwb/cnet/ Brian.
  13. Al, I agree with all the comments above, but on the positive side at least you have tried. Just keep trying. The key thing is to get your message across not your fancy web graphics - I would forget about using flash altogether. I have been designing sites for a few years now - here is a test one for a (nearly) similar line of business which I think looks a bit more professional, please feel free to borrow/steal any bits you want. http://www.blackettworld.com/bwb/cnet/ Or if you really don't think you are up to designing something like this (and I think you are - it's just your artistic skills are a bit lacking) I would normally charge around £200 for a site like this. Keep trying, Brian.
  14. So looking for a 2" widefield (within by budget) I came across the MoonFish Superview series where is says This new Moonfish® SuperView Serie features a modern optical design that allows you to use them on "fast" telescopes - telescopes with a short focal ratio down to f/5 - with respectable field sharpness (but, please, keep in mind that the exit pupil does not get too large with the long focal length Moonfish® eyepieces, though. For example, at f/5 you may well use the Moonfish® SV32mm, but the Moonfish® SV42mm and SV50mm will render a not-quite-useful exit pupil of 8.4mm or 10mm, respectively. The exit pupil should never grow bigger than your own eyes' pupils can, otherwise you will waste light.) I guess this recommends a 32mm, but I think that with a Dob I need a wider field to more easily find DSOs so I guess I would need lower magnification. This is where I get confused about magnification and FOV. If you use 2 lens with the same FOV but different magnifcation what does the eye see differently? Going for a SV42 or SV50 would mean a would 'waste light' but would it be better? Would it mean having to tilt my head to see the whole FOV? Another option is the Moonfish 32mm Wide Scan 70° 2" Eyepiece Any Dob users our there with some tips? Thanks again, Brian.
  15. Found this on wedges http://mysite.verizon.net/res6jv9o/astronomy-trains/id13.html Brian.
  16. Akyra, Yes Venus is in the East (West - woops), in Auriga. At x120 it looks like a small version of our Moon about 75% full. Brian
  17. I'm after a wideangle eyepiece for my f10" f4.7 Dob. I've read a few posts which talk about scopes being fast and slow and have guessed that f4.7 is fairly fast. I understand that this has an effect on the size of eyepieces you can use before the edge starts vinagretting?? My scope will take 2" and 1.25" eyepieces. Could someone please explain fast/slow and the impact on eyepieces. I want an eyepiece with a wide FOV for searching for Messier objects and other DSOs. What is the maximum fov I could reasonably use, is 2" better than 1.25", what is the best size of eyepiece for this kind of thing 30mm, 40mm or bigger ? Thanks in advance, Brian.
  18. Great scope - I've just got the Skywatcher version, the boxes and scopes look identical !! Can you explain what you mean by a wedge for tracking? Thanks, Brian.
  19. Excellent video - makes me want to get out and give it a try!! Brian.
  20. Found this :- http://www.cloudynights.com/item.php?item_id=362
  21. It's a steep learning curve trying to work out where to point a Dob, I can find the Moon and Saturn easily enough but have had a lot of trouble trying to find any DSOs. Well after about 4 hours trying, using Turn Left At Orion, I happened across M44 the Behive Nebular I decided to have a go at sketching what I saw and this is what I came up with. This was using a 25mm eyepiece - so at around x48 I'd appreciate it if someone can confirm that I did actually see M44 :? Thanks, Brian.
  22. Thanks Upgrader - that worked really well, unfortunately my eyepiece doesn't work anymore, it melted a bit around the rubber eyeguard and wont fit in my focuser anymore. Anymore useful ideas on where I go from here?
  23. Interestingly these eyepieces don't look like the ones on FLO. And another 'genuine' seller is slagging off the 'fake' ones. Checkout these 3 links. FLO : http://www.firstlightoptics.com/proddetail.php?prod=ms4000sp 'Genuine' : http://cgi.ebay.co.uk/Meade-Srs-4000-Super-Plossl-40-0-mm-eyepiece-1-25-BNEW_W0QQitemZ290107592906QQihZ019QQcategoryZ3636QQrdZ1QQcmdZViewItem philip55025 : http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ih=012&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=220107058959&rd=1&rd=1 The philips55025 one has a much longer nobbly finger grip bit. All very confusing...... Brian.
  24. Excellent idea! I've a couple of spare bits - so will try it.
