  1. I find my best views of globulars come through my mid power eyepiece (a vintage 10mm orion megavista) which in my scope gives 75x magnification. Higher mags are useful for the fainter globs to try and tease out a bit of resolution (eg m 53 in coma and m 56 in lyra spring to mind but i do only have a 5" scope!), but seeing a bit of sky around them always makes them look nicer!! HTH Adam
  2. I'm thinking of buying one of these as a travel scope Telescope House Revelation 62mm Four Element f8.4 Achromatic Refractor (Black)as i'll be going to the canary Isles soon and they have nice dark skies!! At first i thought i may be a reincarnation of the WO ZS 66SD but with a f ratio of 8.4 it's a lot longer. The price is certainly good and it comes with a soft carry case. Anyone bought one and can share their experiences?? I suspect at 62mm and f8.4 chromatic abberation won't be an issue so as long as the optics are good it should be a winner!! Thanks Adam
  3. Olly i do agree with the anthropocentric view point we take about the universe but I guess that just our intrinsic prejudices, hence why we name planets, moons, topographic features after people, gods etc of the past! This view point has even gone so far as to have created the anthropic cosmological principle which the states the universe couldnt be any other way or we would not be here to ask questions about it! Of course this principle assumes it's presumptions and so is of limited usefulness however I'm always slightly reluctant to agree with multiverse theory as is purely theoretical and being a scientist myself think of things needing to be empirically tested. The slit experiment does show circumstantial evidence (according to David deutsch) for alternative universes though I personally see them as one of the perculiarities that come out of quantum theory! It's all very interesting and whatever peoples thoughts on how we can think about and comprehend these things i still find it amazing that homo sapien sapiens can do so Thanks Adam
  4. Opps my bad! First time i've posted in here and i will keep that i mind next time in delve into the incomprehensible! Blackparticle that was something i has thought about but not heard that once everything has spread out and time and space to do really exist per se it could all start again as i guess that is the 'nothing' out of which the big bang took place or the creatio ex nihilio. Its the eternal return which Nietsche so loathed the thought of!
  5. After recently re-watching the first episode of wonders of the universe it raised the question in my mind again about the end of the universe and what a anticlimax it all is. If we now think that dark energy driven expansion will eventually spread out the universe so much that even all the protons are split apart then nothing happens forever (even though nothing can actually be said to be happening because, thermodynamically speaking, the universe is completely homogeneous and so entropy cannot increase, therefore the arrow of time has ceased being useful and time has stopped !!) it seems like an awefully meek ending to something so grand! Now don't get me wrong all of this will happen long after we're all gone and so the time we live in now is truely the best time to exist (especially for astronomy), however as i'm not too familiar with what the various religious eschatologies are i wondered how they deal with this infinite nothingness?? I appreciate this a slighly deep question however i guess its because we all think of everything having a beginning and an ending that i think i god created everything the He couldn't be happy with that situation?? Thanks for yout thoughts and i apologise if this offends anyone Cheers Adam
  6. Morning all! Just seeing if anyone else managed to get any decent views of the Europa tansit last night? As seems to be happening a lot this year when the sky is clear the moon is out to prevent any DSO observing but as it was forecast to be clear all night i set the alarm for 3.30 plonked my scope outside and had a quick hour. I was using an Intes MN56 so it took about 30mins to equilibriate, but once it had i was able to use 200X (a 7.5mm ultima and 2x TV barlow) and get a pin sharp view of the shadow on the disc. Any way this was my first proper go at jupiter this season and it reminded me what a dynamic object it is to view, always something going on! Cheers Adam
  7. I agree with swamp thing, regarding the narrow FOV. The best views i've had of NGC 7000 have been with a 66 sd and a 22mm panoptic and UHC filter which gives almost a 4 degree TFOV and nicely frames the whole nebula. It is only a very subtle brightening and so being able to see all of it with some space to spare really helps you see it! The west coast around california and mexico are the brightest parts and i would imagine your 10" dob gives to much magnification. I agree with swamp thing ditch the dob and reach for some binos or a rich field scope to get the best views. Cheers Adam
  8. From my experience a UHC filter is for this object and I've found small aperture still gives great results! I can see the veil nebula from my suburban backgarden with a 66mm scope and UHC filter! I think for both these objects good transparency is essential to get the best results!
  9. Interesting responses, I had my best view last summer from the new forest with a 66 sd and it seems smaller aperture may be best owing to it's low surface brightness. MjrTom I'm sure the combination your taking to ireland will give you a great view! Olly you should use your zs66 and put a eyepiece in which gives you at least a 2 degree tfov and a UHC filter and you can't miss it! It is only a subtle hazy brightening but I find the coast and peninsula to appear most obvious! I'll try a sketch next time I'm out I think! Cheers Adam
  10. Evening all, Having bagged ngc 7000 for the first time last night through my zs66 sd I wondered what equipment or techniques people seem to find helps with this? Last night a I used a 22mm panoptic and lumicon UHC filter and it gave me a good view, got it all in the tfov and I found the Mexican peninsula to especially stand out. Anyway I'd be interested to hear your tales of observing this great summer object and the equipment used. Cheers Adam
  11. So it was a bit hazy here on the southcoast yesterday so didn't think it would be worth setting up the scope but after watching family guy I looked outside and the sky was very clear and black! Once I set up after 20 mins I could cleary make out the milky way from cassiopia right down into saggitarius! I could also see the scutum star cloud clearly which I've never noticed from my back garden and it was an amazing area to scan around! Bagged m11 and 26 but also saw a globular I'd never noticed before, it was small but had a bright core. No resolution was possible but at 130x there was a granularity. I later confirmed this was mag 8.2 ngc-6712 and will be an object I'll visit more often now! I also observed the globulars m 71 and 56 which I always love as the starfields they lie in are so rich! M71 in particular showed about 25 members and I even got a couple out of 56! I then moved up to 27 which with a lumicon UHC showed the typical apple core shape with more diffuse nebulosity at the edges. I decided to finish with the veil nebula which due to the excellent transparency showed excellent detail! Very wispy and I could make out the filaments in the upper part of eastern veil. I also thought I could see some of ic 1318, some of the emission nebulosity around gamma cygni but it was very faint! In all it was a very enjoyable night and living right near the beach I can get some very good nights! I would estimate limiting magnitude to be +5 based on known star values I could make out and the instrument used was an Orion optics 150 f5 1/8 wave and is quickly becoming one of my favourite scopes I've ever owned! Thanks Adam
  12. I use an 11m t6 and 2x barlow as my planetary eyepiece in my tal 100 and found to perform very very close to the 5mm setting on the 3-6 nagler zoom which is regarded as one of the best planetary eyepieces. So good is this combination I've never felt the need to get another eyepiece and the wide afov really helps as my mount is undriven! Hth Adam
  13. Is this stil planned to go ahead?? The forecast is looking good for tomorrow night at the moment!
  14. I would say that the under correction in your scope is one of those things you'll have to live with and is often a consequence of buying mass produced optics. On most nights you may not even notice the difference between a better figured mirror however if you want top optics (eg 1/8 wave correction and high strel values) you need to pay extra for it, hence why Orion optics scopes are far more expensive than the ones you may get from sytna etc. IMHO i would be very suprised if a supplier would consider exchanging your scope based on the star test images you've supplied and once you go down the road of trying to quantify the quality of your optics you'll soon only be satisfied with the best, which comes at a large price! HTH Cheers Adam
  15. I have a 35 panoptic and do find that eyeposition is important. That being said once you find your spot its very comfortable and is a great widefield eyepiece! Also it good for the veil and N.America nebula with a good O-III filter! I was out having a good view of the veil last night and even in at tal 100 F10 it still got a good chunk of it thanks to its wide AFOV. HTH
