  1. I have the 6mm Omni which is useable (just) but to be honest it's quite uncomfortable. I'd imagine that it's way overpowered with a Barlow it's just not a good enough eyepiece to support x2.
  2. Bizarre. Still, doesn't sound like it's going to be that bright though..... Certainly not enough to affect astronomy? Perhaps time to start regulating what actually goes up in to Orbit and creating yet more junk.
  3. I think a 2nd hand standard C8 for the purpose stated would be a good choice. IMHO the focal reducer / corrector is necessary - It does make a significant different to the image across the FOV as well as avoiding really long focal length eyepieces for low power. The C8 suffers quite a bit from mirror flop - and yes this does affect collimation as I tested this one evening with the scope pointing at various positions checking the collimation at various angles. Still, it was a good scope for DSOs and lunar and its portability (I used to hike with a couple of miles) means you can be setup quickly at some remote dark site easily. For planetary also it's a good scope but as collimation needs to be absolutely dead on (which was virtually impossible with the mirror moving) I felt that at high power it was always lacking a bit in sharpness. I think the C8 is a difficult scope to beat though for performance / portability especially at second hand prices. You do need a dew shield and dew strip for it though.
  4. Look out for a second hand 6mm Baader Classic Ortho. They seem to come up pretty often on the used market. Another alternative would be a 10mm Baader Classic Ortho (really great eyepiece) and use a barlow to get 5mm. the eye relief of the 10mm is comfortable (I assume you're not using glasses).
  5. I never really got on with a narrow view. I bought and sold a couple of TV Plossls even though the quality is great. 82 degree views from my ES82s were tricky at first but I got used to them although long sessions with them I found a little tiring due to limited eye relief however I've kept them which form a smaller lighter case. So yeah I've chopped and changed a bit over the last year and a half but now have a set of Delos and a couple of Panoptics which for me have been perfect every time with all scopes I own. Variations in the view are always due to seeing and the scope still cooling down. Perhsps have multiple cases of different style eyepieces to suit your mood?
  6. SkySafari has this at mag 15.4, however if the compact core is bright as states should be visible with 10"+ aperture. I hadn't noticed the galaxy before but will be sure to check it out next time I'm around M57.
  7. The 28mm Explore Scientific Maxvision optically is very good quality. It shows visible coma at f/5 at the at the outer 1/3rd but that's to be expected with any eyepiece at this focal length. Bresser have some ex-demo available of various eyepieces that may be looking at. I've bought from there before with no problem (although the packaging could have been a little better!). The 28mm Maxvision is 75 Euros plus postage (7 euros ish if I remember rightly....) They also have the 34mm ES68 for a good price (no idea what this one is like though...). Alternatively, FLO have a new 28mm ES68 available for £129. I really like my ES68 (24mm) it's very comfortable to use and great performance for the money.
  8. The Veil needs dark skies. Period. A it's so spread out there are very few regions that are bright enough to come through even with the OIII. If your LP means you can only see mag 4.5 stars or less you're going to have a tough time with the Veil. The OIII however will make a difference to actually see some objects like the Veil that otherwise would need exceptionally dark skies without the aid of a filter. Planetary nebulae start to stand out much more or you get more structure to them. M1 is a good example where it's quite difficult without any filter and M27 you see more of the outer layers for example. Still, you need dark skies to make these differences stand out. The UHC being broader than the OIII imho will only come in to play if you have H beta as well in the object (which needs dark sky). A couple of great examples where this filter really works is the Eagle Nebula (M16) and the Lagoon Nebula (M8) both of which have H beta and OIII and are also pretty bright especially in the OIII lines. With the OIII obviously you get the better contrast of the OIII but with the UHC you will see extended structure. However! There have been many times when the sky has not been dark enough for the the UHC to show well these objects as the contrast is lower (being a broader band pass) and certainly not dark enough to show the H beta. For me at least, my sky has to be closer to mag 5.5 mag limiting than 5 to really make this filter work well.
  9. Some of the shops here will ship internationally. I have the Astronomik UHC. The UHC is very good but really only when there is less LP imho. Perhaps look at the ES UHC filter to see what the pass-band is comparing to other manufacturers.
  10. The UHC-S is more of a light pollution filter filter being broad-band. I think really it's of limited use in how effective it is and may be dependant on the type of LP you have anyway. You don't state for your budget if it's for a 2" or 1.25" filter (makes a large difference!) I'll make another suggestion though. The Castell OIII filter is very good. I had this and it worked very well indeed with my 8" SCT and smaller apertures right down to 80mm. It's rather more of a broader band-pass than some of the other OIII filters but nebulae that are strong in the OIII lines come out very well at a dark(ish) site. I found the OIII filters to be used much more than my UHC which I tend to use when there's more H-beta available as well as OIII.
  11. If you get the mount and 80ED with a 2k budget you'll have money left over for an OTA more aperture for visual observation. Personally I think you'll be disappointed with 80mm visually for DSOs unless you live somewhere extraordinarily dark.

  13. Hi Vega. Many thanks, but just after a cheap set of 2" legs... That seems to be the entire CG5 mount.
  14. Great! Don't mind a bit of dust. . Local (ish) as well.
  15. Just wondering if anyone has the Celestron CG5 or AVX (with the 2" legs) tripod spare not being used because you've put the mount on a pier etc... Condition not particularly important as long as it works.
