Hi again Roy & thanks for the heads up on the "Virtual Moon Atlas", It’s downloading now :)..I also found this site for TriStar Map Atlas I’ve downloaded them & am now in the process of printing them of, I will then Laminate them myself as I have the gear to do it (It saves me a few quid rather than buying ready laminated maps) :)…. Also Thanks to Robin for pointing me in the direction of Star Maps, Although they do look pretty confusing to me at the moment. I’m going to look for a Total beginners guide to astronomy so I can start to get to terms with things, I really am that green ;-)… All I really know is when I look up to the night sky I can pick out some of the constellations, but thats about it!! So I have along way to go :)…I’m not put off in the least by all my confusion at the moment about knowing my way around the night sky, more, really excited about learning more & wanting to learn, also to have a better understanding of just whats out there.It’s only now that I’m in a position where I can begin to spend the time & effort to Learn more about this fascinating subject after spending alot of my working life travelling to various places around the world & many of those in fairly hostile environments (worked on Land based Drilling rigs).It’s mostly to do with my interest in photography & wanting to take pictures of the things in our night sky that I’ve often wondered what they look like if you could see them more clearly, Thats maybe the wrong reason by some peoples standards, but it’s whats drawn me to look into it in more detail :).Sorry!!…. I’ve rambled on abit there, I’ll stop now :-)…Thanks to everyone here that are trying to help me, it’s really appreciated & my enthusiasm is going from strength to strength..Have a Good Weekend allNorman

Don’t forget places like COAA in Portugal, great value and good equipment.

Norman, since this thread has moved on to catalogs etc.If you’ve got a laptop the absolute best(IMHO) luna atlas is the "Virtual Moon Atlas" FREEly available on line (though the Pro version is a huge download).When using a web cam on the moon it’s great to be able to show VMA and the webcam image side by side. With the small field of view of a webcam it is otherwise quite easy to get lost and end up snapping somthing entirly diferent to your target! I find the Expert Version entirly adequate for the purpose.Yes I know, I should learn my way round the moon a bit better, but with "Maturity" also comes a certain fuzzyness of the brain.Roy.

Hi Callum,Thank you again for your offer to put the date’s up on the "Other Meetings" Calendar.I have been looking recently. But unfortunately I can’t see them?

Hi RobinThanks for the list & info, much appreciated.. Looks like I’m going to be doing alot of reading & digesting of Information & instructions ;-)..Getting quite excited now I’m starting to get all the equipment & reading material together, Also seeing some of the images that others have got using similar equipment to me, is a real incentive.I know alot of those images are gotten so good with the help of using the "stacking" software on a computer, The computer side of things doesn’t faze me at all as I have always built my own computers from many years back & my present computer which is Water cooled, overclocked & built for high graphics & heavy processing content, so am looking forward to working on my efforts when I get my scope hopefully by the end of the month :)All the BestNorman

Here are a couple of book/atlas recommendations:’The Observer’s Sky Atlas, 3rd. Ed.’; E. Karkoschka; Springer; New York; 2007.’Sky Atlas 2000.0 Field Laminated, 2nd. Ed.’; Wil Tirion & Roger W. Sinnott; Sky Publishing Corporation; Cambridge, MA; 1998.’Sky Atlas 2000.0 Companion, 2nd. Ed.’; Robert A Strong & Roger W. Sinnott; Sky & Telescope Media; Cambridge, MA; 2008.The first is a small paperback and contains a catalogue of 250 deep sky observing projects along with photographs. It contains observing notes for the objects and the presentation is very concise. I would thoroughly recommend this.The second, in it’s various forms (permutations of colour/black on white/white on black, paper/laminated) has become a standard. I have recommended the ‘Field Laminated’ edition which is white objects on a black background (to preserve night vision) on wiro-bound large plastic sheets.The acetate overlay supplied for measuring seperations also has ‘Telrad’ finder circles to match with a Telrad finder view should you invest in one.I find it useful to take a fairly hefty music stand into the garden to place the Sky Atlas on, along with my drawing pad (I’m a visual observer).I have also recommended the deep sky catalogue for this atlas (the publisher seem to have changed name) as it contains valuable observing notes. There are also catalogues of stars available for this but I feel they are of a less importance, details about stars being easily obtainable via the internet.Hope these recommendations are of interest.

Hi GrahamWOW!!!!! Thats a great site you have there, can see you spent alot of time & effort…Fantastic & Congratulations :)..You have wealth of imformation on there that relates to what I was hoping to do, albeit maybe not as clear as some of your images but gives a good idea of what I can get near to with a smaller Dia Mirror (8") on the SkyWatcher Explorer 200P EQ5 PRO SynScan 200mm Newtonian I have ordered & Canon 1000D @ 10megapixel.. :)..I shall enjoy reading through your very comprehensive & imformative pages while I wait for my scope to arrive sometime towards the end of the month.Do you believe that even with my smaller scope & camera that I will be able to achieve some good shots of not just Deep Sky but also Lunar & Planetary close ups?… With the help of your site of course :-)..Thank you for taking the time to reply to my post & help/advice that you provide… That goes to all of you….ThanksAll the bestNorman

The SkyWatcher telescopes are excellent. I have their 250 (10") f/4.8 Newtonian on an HEQ5 mount. The only bad aspect for me was a complete lack of any documentation. A Google search found a manual at http://www.skywatchertelescope.net/swtsupport/Instruction_Manuals/HEQ5andEQ6130405V1.pdf but that still lacks a lot of important detail. I have therefore written a page about my own discoveries of how to use the various parts of the telescope: http://www.grelf.net/skywatcherdoc.html . (I am keen to encourage others to try astrophotography and that was the motivation for my web site.)You can avoid having to guide long exposures at all by taking a lot of short exposures and then using some software to align and stack them. That also has advantages for coping with light pollution and reducing overexposure of bright stars. I describe the procedure on my own site, and you can see some of my own results using an unmodified Canon DSLR without guiding: http://www.grelf.net/astrolatest.html. To use multiple 30-second exposures it is important to align the HEQ5 mount so that Polaris is within the small circle in the setting scope, as described in the PDF file from skywatchertelescope.net .

Hi TonyThanks very much for your input & advice, It’s much appreciated :)I’d never heard of the Telrad Finder, but it does look to be a good buy for someone like myself just starting out.The adapter for the Scope is on order as is the Canon 1000D camera..I do want to Photograph deep sky as well as solar objects & was trying to pick something that would (with abit of maybe filtering or adding certain adapter lenses) that would as a starting point give me some, If not all of what i would like to picture.. But I do take on your advice, so many thanks again for that.Have been looking around for star maps/atlas’s & guides, Doing a lot of reading up & beginning to get a very little grasp of things :). The welcome pack I recieved from BAA has come in very handy for finding information & links :).. Great pack I have to say..Thanks again for your Advice & TimeRegardsNorman

The Camera.You would need to have an adapter so that you could mount the camera on top of the telescope. You then use the telescope as the guide.The TelescopeI do not know the telescope but from the reviews it appears to be good value for money. The only comment I will make about it is that at F5 it is more suited to Deep Sky than Solar System objects. You may want to get a Telrad Finder. A lot easier to use when you are first starting out.Other things.A star atlasSome observing guides.A pair of 10×50 binos to help teach yourself how to get around the sky, (you will be surprised at what you can see in them)

Thanks Nick. I like the price (£4.4s with a 12/6 deposit, or for our younger members £4.20p and 63p – I think :-).In JBAA Vol. 77 No. 4 page 264 (June 1967) you will find the write up to the first meeting. Fifty six "students" attended, and with an assortment of telescopes from a 2.5 inch to 8.5 inch reflectors managed to observe theMoon, Jupiter and Mars through breaks in the cloud, and a sun spot projected with a 3 inch OG. Lecturers were Howard Miles, J. Hedley Robinson, Michael Hendry and Alfred Cuirtis. Not a bad speaker list I’d say!Gary

The first reference I could find in my searchable Journal set was vol 77, no. 2, p74. It was announced as a residential weekend course (in drinking beer?) and ran from 1967 April 14 to April 16. That would put the 40th one in 2006 as Callum said. I’ll see you there!Nick.

Hiya & Thanks for the quick replies :)@ Andrea~~~ Thanks for those sugestions Andrea,Much appreciated :), You do realise I’m holding my head in my hands with shame now…. I forgot my Panasonic SLR didn’t have a detachable Lens… What a Numpty I am.. Sorry about that.. I was thinking about my old 35mm camera which does have that.. Anyway.. many thanks. :)I’ve had alook around & although I can get hold of the Canon 300D I’m thinking of going with the Canon 1000D, simply because it’s around 4 Megapixals larger than the 300D but only £60 dearer (for body only) & so i’m assuming I’ll get a better image quality using the 1000D..I’m going to go with the 200P (I thought that would be the one as it has the 8") & gives me a better chance of catching some Half deccent Photo’s.. Again thanks for your Advice on that also :)@ RoyThanks for your reply Roy & the link :).. Nice place lol.. Am thinking i’ll get one of these as well for when I’m at home sitting at the computer Star Gazing…Will use the Canon 1000D for when I go out to the edge of Bodmin Moor running the Scope off the 12v from the car or bat pack…All the bestNorman

Norman,Note that Philips SPC880 webcams (a SPC900 firmware upgrade is available free, or Morgans will do the firmware mod for you for £2.99) and adapter kits are being flogged by Morgans at the moment. Not as cheap as they were last year but still very reasonable. The SPC900s give very good results on the Moon using software and techniques readily (FREEly) available on the net, just google with somthing like Webcam Astronomy, SPC900, etc.I’ve not had a lot of success with planets. But others with more patience have. Just a couple of years ago they were state of the art at any (very amateur) price.see… http://www.morgancomputers.co.uk/shop/products2.asp?CategoryID=556The various (more info) buttons will lead you into a sea of information, I spent a happy couple of hours surfing this on Monday. Best of luck,Roy

Hi Norman,In terms of overall ability to take long exposures and overall decent telescope and mount I think the 200P the only one the fits the bill. This said I’m afraid you camera (which isn’t a DSLR) won’t be much of help as the lens can’t be removed afaik. This said there are very cheap ways to accomplish at least some of what you’re after by using a suitably and easily modified webcam (Philips SPC900) and taking short movies of the moon and the brighter planets. With further modification (less easily done) even the brighter and smaller of the deep sky objects are within reach.Going deeper and therefore fainter would require:1. A way to "guide" the main scope usually done using a smaller scope in parallel and another "guiding" camera to give the mount the correction in order to remove the small errors in tracking due to the mount main drive.2. A specialized astronomical camera of a true DSLR so that the lens can be removed from a the body and the telescope used in liue of said lens. The best camera for such a job appaear to be Canons and while they can be expensive older generation cmaeras such the D300 as still pretty good for astrophotography.Hope the answers above will help.Andrea T.

Frankly I can’t see the effect you’re mentioning nor I ever seen it in any other image (even from the HST). Maybe foreshortening of the features as the approach the edge (or appearing from the edge) of the disc may explain what you seem to see?Andrea T.

Thanks, thats what I suspected. Why they look like that on the movie I can’t think. The way the leading shadow decreases as they roll up the side of the planet realy sugests that they they are lower than the main clouds.Roy.
