  1. Borrowed a pair of revelation 20x100s (I think?) for a bit - fantastic bins when they were working well - some amazing views through them, but went out of collimation virtually every time they got moved around! I'd love another pair of big bins though...
  2. Hale-Bopp is up there, but as it revealed itself over time and got more and more visible, I wouldn't call it 'satisfying' as such, more spectacular! Also , Saturn, Jupiter were all WOW moment, but satisfying is when I see something I've wanted to see for a long time and it's previously eluded me... In which case, in no particular order... 1) First sight of the Veil Nebula, both eastern and western through an OIII filter in my 12" Dob. This is one object that can go from invisible to spectacular with the addition of an OIII into the mix. Have seen it since in apertures down to a 102mm
  3. The Rosette isn't that hard with an OIII filter, though obviously the darker your skies and the larger the aperture the better. I've got a 12" Dob in skies that aren't that fantastic, and I've managed it a fair few times, but have always needed the OIII filter to do so... I just look for the recognisable central cluster, then I find slowly panning around the area really helps to pick out the mottled nebulosity surrounding it. Once you've seen it, that elusive doughnut is easier to find next time...
  4. Yup - a definitely second on the Bahtinov mask. It makes so much difference. Either that or an auto-focuser, which can wither be bought or self-built, but costs more and is more difficult to set up and run. I'd stick with the mask - you can pick a decent one up (star sharp masks are great) for about £15-20 I think... Or you can make your own one of those too... the following link is a bahtinov mask generator that you can use to make one out of thin foam or similar yourself.... http://astrojargon.net/maskgen.aspx
  5. Thanks Peter. It takes a bit of playing with the proportions in which you mix the OIII and Ha into the various channels. Also, re-merging the Ha as an additional luminance layer gives it more 'pop' and really boosts the detail in the fainter parts of the nebula.
  6. Yes - I noticed this one too, but it wasn't enough to bother me that much. Would of course prefer to eliminate it. I do have a flattener for this scope, but unfortunately it's not compatible with my current imaging train. This little ED70 doesn't have the flattest field ever, but its strange that it appears to be more pronounced in one corner.... I'll have a play next time I use it (recently been imaging with my 102ED more...).
  7. Great kit to start out with! Welcome to the fold!
  8. Cheers Good old Bonusprint Makes me think of the envelopes you sent your films off in in the 80s after your holiday, with a cheque, to get them back a week later....
  9. Was that in the UK? Have been tempted myself... who did you use?
  10. Definitely agreed that for 600secs integration that’s a heck of a result on such a dark object!
  11. I love the two jets emanating from the top of the feature I think David's referring to on the right. Apparently caused by the solar wind from a young star behind the dark cloud...
  12. Hi Everyone! It's been a while since I posted any of my images, but I've been working hard to improve my technique over the last year, and combined with the move from DSLR (Canon 1100D) to CCD (Atik 314L - not the plus one ), I've been waiting until I got it all sorted and I was starting to be happy with the results. So here's my first ever bi-colour Ha/Oiii image - The wall region on the North America Nebula in Cygnus. Details as follows:- Camera – Atik 314L Mono Exposure – Ha – 2hr 20mins, OIII – 3hr 15min Filters – Astronomik 12nm Ha Filter, Baader
  13. Ah! Interesting concept and execution..
  14. I would prefer without the car, but I think there's a reason for leaving it in there - i.e. it shows it's upside down - made me thing for a split-second anyway Can't think of any other reason it'd be there, as it's so easy to 'shop out...
