  1. Hunting for 3C273

  2. Revolution Imager held at the post office awaiting customs payment... How does one go about doing that?

      Go to the PO on the card, take card with you and pay the fee.
      The actual place they hold ours is the local sorting office not the PO in the town.

      They may ask for ID but whenever I have been to our PO the card is the ID.

  3. Completely replaced my eyepieces. 9, 14, 20mm ES 100 deg and 30mm ES 82 deg. No more soda straws.

  4. First night with the 20mm ES 100, all I can say is... wow

      I'm pleased you're pleased...you made the right choice. Regards, RL

  5. Bit the bullet... first 100deg eyepiece on the way

      ES 100 20mm :)

  6. How are you supposed to use dew heaters? Do you just turn them to maximum?

      the trick is to put them on before dew forms, what are you using them on.

      That makes sense, I left the heater on low and came back after a few hours to see dew on the corrector plate. I turned it up to max but there was still big ring of dew around the secondary that wouldn't go away. I am using it on a C11.

      On my C8 I just put mine on full from roof opening, never got too warm and not had any dew (touch wood ) .

  7. Finally saw the Veil... in a 12" refractor!

      Sorry to hear that ;)

      ??? Cambridge, 12" refractor, Nothumberland perhaps ??? Seems a bit unlikely as IoA has copious amounts of light pollution (usually).

      Yes, that the one! I used my own OIII filter and eyepieces ;). I couldn't see it at all without the filter.

  8. I just had my first opportunity to use my new CGEM 1100 after getting it more than 2 weeks ago from FLO. I am impressed enough that now I want to tell everyone about it. There will be annoyed people in the lab tomorrow. I upgraded from a C6 SCT on a non-GOTO CG-5 which I will still use a really convenient grab 'n go scope, but as I had hoped, the extra aperture really makes huge difference. I was observing from a non-ideal site with a building blocking up to 40 degrees altitude in the north, east and west directions, with lots of accompanying lights. However, the seeing was good after the clouds went away and it was warm enough to be in a t-shirt for the entire session till 1am. Skies were just about mag 5 NE limit towards the zenith with a hand blocking the offending lights. So, I was trying out lots of shiny new kit for the first time: the C11, the CGEM mount, a 2" WO dielectric diagonal and a 40mm WO SWAN 70° eyepiece. Setup took much longer than with the 6", as expected, and I stubbornly tried to perform a 2 star align without using a finder, before conceding defeat in a rapidly losing battle. However, after getting set up, I can see that having GOTO is really, really convenient, despite taking away a fair chunk of the fun. However the 11" is a bit too big to unclamp and manhandle, and it doesn't let you do that without losing alignment anyway. Onto the actual observing; I started with the same targets that I tried last week with the 6" for comparison: M13 - With the 6", this was quite fuzzy blobby, and contrast wasn't great due to the gibbous moon. Some of the edge stars resolved but the core was a single mass. With the 11", wow, looked stunning with the 40mm, with lots of the brighter core stars being resolved, the longer time spent at the eyepiece the more could be picked out. Even more so with a 15mm SWAN, although I noticed the collimation may need touching. M57 - GOTO put this dead centre slewing from M13, not that it is difficult to find, but I was impressed by the pretty quick slew speed. With the 6" and 25mm, I could just about make out a bright blob. Going up to 15mm with a UHC filter gave enough contrast and size to make out the ring. 11": Bright and easy. Ring structure was visible at 40mm and 15mm #nofilter. Some greenish colour was perceived too #nofilter. M27 - Once hard to find, but has got much easier since I got a Telrad on the 6". The structure was not really apparent, just about visible at 25mm with filter. 11": I had the 15mm with filter in and the GOTO placed it dead centre again after a meridian flip, but still took about half the time it would have taken to find it myself. Nice. Shape and structure easily visible. Pleasant star field too with the 40mm. M31 - In the direction of bright lights, but the core was easily visible in both. Sky was too bright to see much of the outer regions though. M33 - Couldn't see this in either. Was very close to building. Another meridian flip. M51 - Couldn't find this in the 6", even matching the field stars I was not able to see it. Sky was too bright. With the 11", I was able to easily see the two cores together. Albireo - Colours looked richer in the 11" Double Double - Much easier to split with the 11". Then I ran out of things that I had tried for in the 6", so I continued with some other objects, including more obscure ones the hand controller said was there, but then pointed at some trees or buildings after performing a meridian flip. Hooray for not looking up where your objects are and relying on GOTO. I know there is a horizon limiter but didn't bother to use it. Wild Duck Cluster: Went behind some trees contiguous with the building. M101 - Just about managed the core. Was very close to the building's lights. Mini coathanger - Looked like a coathanger, small. Coathanger - Couldn't fit the entire thing in the 40mm SWAN. Nice and bright though. Kemble's Cascade - Nice to follow with the 40mm. No way was I going to fit it all in one view. Then I had another few more looks at M13 and M57 before packing away, due to the need to work tomorrow, which I have completely disregarded by writing this all for the past 2 hours. Oh well. I am very impressed. The 11" is really nice. GOTO, I'll admit, is quite nice when it starts working, and so are wide AFOV eyepieces. I haven't tried a comparison between the stock 1.25" mirror diagonal and the 2" WO dielectric one, but I probably won't bother. I would like to be able to find things myself in the future, which you can apparently do with a park feature on the CGEM, but I will wait until next time after I have installed a Telrad mount. I will be moving down the road in a few months to a house with an accessible roof terrace thing which is shielded from the street and has a good view towards the south, west and north. Unfortunately I will be on the ground floor, but carrying it all up and down 2 floors isn't insurmountable. Hopefully, the views and object choices get much better then. Otherwise, I will be stuck begging for lifts to better skies.
  9. Upgraded to an 11" from a 6" 2 weeks ago... not a clear night in sight.

  10. Saw a meteor stretching about 40 degrees across the sky directly above. Occurred around 2:10-2:11am 06/7/10 and lasted about 2-3 seconds. Very bright, brighter than Jupiter that just happened to go behind some trees causing me to look around the sky in no apparent direction when It streaked across. Did anyone else from the North Hampshire/Berkshire region spot this?

    Ordered some Baader Optical Wonder with cloth on thursday evening, went away for Friday and Saturday. Was pleasantly surprised when I got back and found the package on the doormat today. Thanks very much!
  12. Actually, I as far as I know there are not many people that are interested, instead the job of using it has been thrust upon the unwilling hands of the boarders that reside in the school. I believe there is a CCD camera included and the whole setup is to be computer controlled. I am not sure about filters though, I will ask to find out; there are quite a lot of low pressure sodium lamps in the surrounding streets, they should help alot with that.
  13. No, a state grammar school in Reading. I spoke to my physics teacher who applied for the grant and he said I was welcome to come visit at any time to use the observatory . Now its a question of the weather and the somewhat abundant light pollution in the middle of Reading.
  14. Today I had my last exam, physics and it contained a fair deal of astronomy questions . This means I have reached the end of sixth form and I have left my school of 7 years. Now for the annoying part, only now have they received a grant to build an observatory in the grounds, meant to house a 16" Ritchey-Chretien and an apo astrograph. This has been in the works for several years and it is only now that they get around to doing it, just as I leave the school.
  15. I only just woke up an hour ago after staying up to see Jupiter and Uranus on my 6" SCT. Saw all four moons, one of which was very close to the disc of Jupiter, checked Stellarium and it turned out to be Ganymede. Saw the main cloud band but not the spot, was quite misty where I was looking from. I also saw Uranus, looked like a small, dim blue disc that looked quite obviously not a star. Morning made good use of my new 7mm TS Planetary. I never realised that Jupiter would fill up quite a sizable proportion of the view at high power.
