  1. Hey, Mount is in my signature (NEQ6 Pro, powered by a Celestron Powertank) and the lens is the standard stock lens that came with the Canon EOS 450D, think its a 18-55mm lens. Only had it zoomed in by about 1/8th to cut out the house and trees. Manually focussed using the LiveView feature on the camera, going to have another go at processing it see if I can grab some more detail from the Milky Way, I needed more subs though but I was in need of bed and didn't wanna wake the rents up.
  2. Taken last night, not ideal as it was the longest amount of daylight. Images taken around midnight, 5 lots of exposures of varying times from 2 minutes to 4 minutes, all at ISO 400. Tweaking in DSS needs some attention. Enjoy.
  3. Hello, this is a blast from the past. this thread was started way back in 2007. thanks for reviving it. Ah, so you've moved into NY eh? cool cool. I'm near Northallerton, there are a few places to go for dark skies around here. I know that the Moors and the Dales are the best places to go but even near town the MW is visible throughout the year : ) I know there's a society at Durham Uni and one for Darlington. Though the LP from Teesside and Durham may not be that good for observing. hmm, facebook? I think I removed that page as I was promoting (at the time) North Yorkshire Astronomical Society. When it came to it then I was advised that a society preferably needs some real-world venue for hosting meetings etc and not purely be an internet based scheme. I thus changed the naming to North Yorkshire Astronomy and worked on a webpage for a year. I unfortunately gave up work on the website in early 2009 due to work commitments...and a bit of laziness. Its still alive and well though and kicking around in first place on Google at northyorksastro.googlepages.com News pages are out of date but the factual content is pretty much timeless. I had Google Analytics attached to the site and in the months I had it working I received over 800 hits from all across the world, with the average time spent on the site at 4 minutes. That impressed me a lot, usually people just browse a page or site for a few secs and click off, 4 minutes of browsing on one site that isn't a forum or long-text site is good.
  4. just claim its a duck house and they'll let you build it no problem. hey, they might even give you some expenses towards it.
  5. hmm, i'm an avid user of iTunes and hadn't spotted that one before. its good, but the astronomy section isn't massive. I had a peek at the Open University lecture and it was quite old. The presenter was cool but I couldn't stop thinking that the information is somewhat out-dated, going by the quality of the video then I would place the video as being mid 80's when made (?). iThink (lol, notice that!) that Apple should allow all the iTunes store stuff to be free. The profits they get from people buying the iPod and iPhone should fund it.
  6. I know of a campsite in Devon, just North outside of Combe Martin on the road to Ilfracombe. Its kind of on a hill but the hill is on the edge of the coast so you have pretty flat horizons to the North and East. The sky on a clear night gives spectacular views. Otherwise try somewhere in Dumfries and Galloway, Scotland, they have pretty much the least light pollution in the whole country. If you want to do a B&B then I'd recommend this place: Galloway Astronomy Centre I would recommend the Brecon Beacons aswell, make sure your well North of Merthyr Tydfil though. Would also go for somewhere in the North York Moors, the nearest built up areas being York or Middlesbrough, both of which from the centre of the moors are about 30 miles away.
  7. 8" Dob 8" Schmidt Cassegrain 8" Pen...... i'll stop there
  8. I would use the pen cleaning device for obvious bits of stuff on the mirrors. However you can clean them quite easily yourself using nothing more than warm water, washing up liquid and a nice soft towel. Simply remove the mirrors, wash them under a shower head in a warm water, then apply a liberal amount of washing up liquid and rub gently in circular motions the mirrors to remove obvious areas, you shouldn't press too hard obviously but hard enough to feel the dirt come away with your finger tips. Wash your hands off then tilt the mirror and wash off the excess liquid, then maybe repeat again to get the clarity your after, the running water should show any sticky areas, then leave in a stable are on its side and allow the mirror to semi-dry off naturally for about 5 minutes or so, when you come back you can place the mirror surface down on the soft towel...beware not to rub the mirror or move the mirror when its on the cloth as you can scratch it. After a few seconds pull the mirror directly up and the water marks should have gone. You should now have a shiny looking mirror. You can use distilled water if you like, its maybe preferable for the rinse section. (please note, this is only a way I found from the internet, if you don't like it don't do it, worked fine for me though.)
  9. Yorkshire has a flag.....but it reminds me of Leeds football club, eugh! Maybe I should just have one of Yorkshire Tea : p
  10. Go Paul! lol, jk, erm Paul's stateside friend knows quite a bit about imaging. But that doesn't have to influence your choice, I would find something that fits your budget aswell as your needs and give it a go. (Paul what's with the massive flag dude?....get a Yorkshire one!)
  11. There are two types of Gamma ray bursts, long and short (hard and soft), depending on the orientation of the star and the burst then levels of gamma ray may be higher. I wrote an essay on it somewhere.......... see attached Gamma Ray Bursts Essay.doc
  12. hey, thanks for the replies. its not that I don't see the shape, its just that I see two possibel shapes. As many of you have said there is the smaller seahorse/chess piece view which is of the head looking away to the left or there is the larger horseshead (why the long face) type look with a horse with a white bit down its nose. I'm now more inclined to go with the chess piece / seahorse view of the nebulae. Its a great area, obvious named objects including theis would be the whale and hockey stick, cigar galaxy, sombrero galaxy, eskimo nebula etc etc. The crab nebula is beyond me however.
  13. Its a common phrase 'the Horsehead nebula', been looking at images of it since I was about 14, its pretty cool. (silly question on its way) However, to this day I do not exactly understand how it is called the Horsehead nebula....I mean which part of it do you get the Horse's head from? Below should be two images showing a blue circle around the areas I thought may or may not be it: The first image is how one person described it as being like a chess piece, the second image I can only grasp as the nebula being based on a horse with a black head and white centre down its nose?

    Newbie questions

    Hi Layor, welcome to the forum. Mid Wales can be very good for observing. You have chosen to maybe go for a Maksutov-Cassegrain yeah? Can I ask why? If I were starting off then I may be more inclined to choose either a refractor or Newtonian design. I mean, by all means go for a Maksutov or Schmidt if that is exactly what you are after but I would state that a Newtonian gives the best all round performance. Mak's and Schmidts don't give exceptionally bright views and the field of view can be quite 'small' with some objects. Saying that though they are more compact and less hassle to maintain than a Newtonian. Just a thought thats all! Celestron make good Schmidts and their small 4inch Mak I had was easy to use and performed well especially with planetary and lunar imaging. Skywatcher stuff is generally good, the refractors are pretty neat, not used their Maks but the Schmidts seem on par with Celestrons. Maybe avoid TAL scopes, they are builts sturdily but they can be a pain to use (in my experience). Haven't used any Meade equipment so can't say.
  15. I've seen pictures of the Crab nebula before but this is really good. Thanks for sharing.
  16. Thanks for that. It was probably what I had heard.
  17. Its cool isn't it. looks like an out of focus star at first. Viewed it in many scopes, its very faint at f/10 but a fair bit brighter in an f7, adding a barlow takes the brightness off, it is really small when compared to the Dumbell nebula (M27)
  18. Best Astronomical Moment Quite simple, it can either be from watching something on TV such as Saga's Pale Blue Dot speech and Kennedy's 'We will go to the moon' speech or something more personal such as a friend trying to understand you whilst explaining exoplanetary detection methods. Or seeing someone drop a very expensive item, aslong as its mildly funny that is! Mine would be during second year at university, a friend and I headed out one dark night to take some pictures of the constellations high up on the hills opposite campus. We got lost on the way there twice, then found at the end of this very long farm track a place to park up. My friend was driving, she reversed the car in the pitch black into what we thought was a perfectly stable area, when we opened the doors it turned out that the car was only centimetre's away from a 5ft drop into a fast flowing stream. If we had fallen in I dread to know what would have happened, there was no mobile phone reception and we had no supplies (whoops!). Anyway we setup in this field to take a picture of Orion, noteably the belt, when along came this rather curious horse to see what we were doing. My friend was quite worried as the horse looked quite menacing in the dark. The irony was that the horse decided to place itself exactly infront of the camera, so to look through the viewfinder you would of seen two 'Horse's heads, that of the horse and that of the nebula. We didn't have time to take a photo, my friend was running out of the field with me close behind carrying the tripod. I think astronomy and observing is better if its shared
  19. I don't think there has to be such a black and white reasoning to all this. On one side we have people saying its not industry Another saying it is industry Others saying its natural and a minority saying there is no change at all I would safely say that you could include the first three of that list and there-in would lie your answer. Global warming cannot solely be linked to one source, there are a number of factors involved. However, as stated above the fact that over the last 300 years we have produced far more levels of CO2 etc then it is probable that global warming has increased more than it should of naturally. The Earth goes through periods of cooling and warming, you can see that from mass extinctions, glacial tracts and other forms. I would be quite inclined to state that human technology and industry are a key factor in this current period of climatic change. On a personal note it is something we can't really ignore, I dare say the environment is a much larger worry than the banking crisis. You can argue this case by saying we aren't seeing that many effects of global warming (yet) but I can retort with did you see the banking crisis occuring months or years before it happened?....probably not.
  20. Grand colourage and nice focus. I find with mine that it always appears slightly out of focus. Its a good image!
  21. That's a great reply. Its very encouraging to note that your local MP has the nous to note that the new coalition is there for a fresh and decent reason. Good on you and good on him. It would be really appreciated if more MP's took the time to not only read the public's informed and educated letters but to, like we see here, send them on to higher resources and persons who can influence policy and law making. All the best on this topic.
  22. Hello, I remember a few years ago there was a program on imaging with a series of scopes (presumably in Chile / Hawaii or somewhere) whereby the fact that two or three identical scopes were trained on the same object then the resultant images in effect gave a result which was the equivalent of having a primary mirror the diameter of the distance between the scopes. Thus the image was a lot better than using one individual scope. Corrections welcomed if wrong. Could this method be replicated with say three smaller amateur scopes?
  23. Ah right, cheers forum friends. I shall wait until tonight and see if the sky is clear, see what the results are of a nice observing session.
