  1. Welcome. I joined a few months ago and have found the Guys in the Forum always will to help us newcomers. Enjoy it. Robin Celestron 8iSD, Canon 350D
  2. Martin Fantastic. Many thanks for your help. I didn't know that the images I captured contained so much detail. I has given me hope and a reason to try harder. Robin
  3. Hi Thanks for the reply Capt. and the explanation of the jargon. I stacked them by Keiths Stacker on my MAC as when I tried adding the first frame to Retrostax it started aligning it and going to stack before immediately before I could add another. This is probably something else I am doing wrong !! I have attached a single frame as requested of the M82 only. the M81 frames were similar. It is great that there are people like yourself out there to help. I am a little too old in the tooth to be up to date with modern technology which manufacturers don't seem to realise when they publish their
  4. Hi Thanks for the replies. As with learning about astro photography, I also need to learn about abbreviations. What are "Subs" & "TBH" ? Thanks Robin
  5. Hi Being new to astro photography I will appreciate your constructive advice on this composite pic of 81 & 82, stacked 5 images, taken with a Canon 350D, prime focus Celestron 8iSd, 40 secs each, ISO 1600 Thanks
  6. Hi I have just started using my new Neximage camera with reasonable results on Jupiter considering the low altitude it is at the moment. I have searched for data & information to help me on my way and was greatly helped by an article by Mike Swanson on the Nexomage imager. I am however not sure what he means when he says that he sets his output size to 320x 240 as he has had better results than at 640 x 480 ( which I have been using ) I thought that this output size did not affect the results or operation of the capturing but was just to give a larger window on the laptop for focussi
  7. Hi Thanks for all the replies, it seems that my main fault was using too many frames per sec. Last night I set the camera at 5 FPS at 30. 60 & 90 sec duration and got good results considering the low altitude of jupiter and the bad sky quality. Thanks again, this is really an excellent Forum especially for those new to Astronomy. Robin
  8. Thanks all I have now solved the problem thanks to your advice, which turned out to be over exposure. I Caught Jupiter last night behind much crappy atmosphere and got reasonable results considering. BUT after taking the images OK I find a problem with Registax in the Optimizing stage, it takes ages. I processed images at 30 FPS 30 seconds 1/50 shutter speed it aligns fast enough but takes 2-3 hours to optimize. I have tried various ways of processing but all take ages. Is this right? it doesn't happen with Keiths Stacker. I have a new Laptop 1.7 GHz and other image files seem to be fast enoug
  9. Thanks for your reply. I am ok with Registax it is the settings on the Neximage I am having problems with. In the instructions they dont give any suggestions as to the settings except for the moon. I have tried moving the brightness adjuster, dark and bright with no result, still a blank white disk before and after stacking. One thing I have noticed is that the images take ages to optimise, could they be too over exposed, but then I don't see any adjustment on the Neximage camera pane to adjust. It only gives Frames per sec 5 - 30 Time ( if I try over 30 secs the Registax wont take it. Over 1
  10. Hi I have just set up Registax on my Computer and have had two frustrating nights trying to image Jupiter. I think that I am doing something wrong as I cannot gey any detail whatsoever on the resulting videos, just bright clear of detail discs.. I have tried many settings on Registax and I havn't a clue as to what setting to use for a Planet such as Jupiter. It is possible that I am not focussing correctly. I focus until I can see Jupiters Moons on my Computer screen, maybe this is wrong. Help !! Robin Celestron 8iSD. Neximage imager
  11. Hi I am beginning to get to terms with astro photography using my Canon 350d. I have been taking pics of Jupiter using an extension containing a 26mm EP. The images do show faintly the cloud stripes but the image is quite fuzzy, mainly due to the bad sky I am taking them through. My Camera is set at ISO 1600 so as to use the fastest shutter speed as possible. Is my thinking wrong, should I be using a lower ISO rating, would this give me clearer images. Lots of questions but only by asking will I be able to get the answers to enjoy what must be the greatest pastime or hobby ever. Robin Celestro
  12. Hi Tried the hole in the card and the moon filter, both worked well for viewing. I think that the haze must have made it all too bright. Also i took some photos of Jupiter though a grey moon filter and they were better. I will now wait for a good seeing night to try again. Thanks Robin
  13. Thank all for your replies. I have some things to check out now. The Moon filter seems a good possibility for my impression of Jupiter was that it was far too bright just like Venus was last year. It was hard to filter that down to a image and need a moon filter. I will wait for a good seeing night and make some experiments. Thanks again Robin
  14. Thanks for your replies fellows. I do wear glasses and have tried viewing with and without. Dew is not the probem and the Scope is perfectly colomated. Last night a pal of mine looked throught the scope at Jupiter, the sky was quite hazy. and he witnessed the same unstableness of the image when as he said " I move me head slightly " He seemed to think that this is caused by looking thought various sections of the curvature of the EP top glass lens, that is the thickness of the glass varies. I know that if I could keep my head perfectly still the image would do the same. I know that all this se
  15. Hi Can anyone out there help me. My problem is that I am getting a bad image when focusing on Planets and bright objects such as stars. The image I get after carefully focusing is like looking at a bright street lamp on a misty night. Last night I focused on Jupiter, it was extremly bright with a glare or fringe of light aound it which made it impossible to determine any features. It was also unstable. When I move my head even the slightest the image splits or ghosts. I had this problem with my old ETX125 and though that when I purchased my new Celestron 8i SD two months ago the problem would
  16. Hi Any views or comments on the Moonfish 15mm eyepiece. Robin Celestron 8i - Canon 350D - Bolshi Red Setter
  17. I am new to Astro photography and could do with some advice. I have a Canon 350D and use it with my Celestron 8i. I have taken pics of M13 & Jupiter with some sucess and would now like to tackle M57 which is very faint at the moment when viewing it. Can anyone advise me as to the exposure time etc I should tryto obtain a goodi mage and the ISO rating using prime focus. I also have a Tele Extender which I have used with a 26mm EP on Jupiter but this seems to me too adventurous for using in deep space. Any advice will be most appreciated.

  18. Hi I had a Meade ETX125EC for two years, got fed up with the goto which was way out despite training etc. Now have a Celestron 8i SD, super scope, as light as the Meade. Spot on with the goto, easy to set up etc. Say no more. Robin
  19. Hi Tom Will try that. To help I have bought a Canon Angle Finder to save breaking my kneck trying to focus. It also has a 2.5 times magnification which also shoud help. Robin
  20. Hi Steve Yes , but now have, see " forgot Pics" Planetry Would appreciate your comments. Robin
  21. Hi Sorry I forgot to include the pics I took Robin I hope these images upload OK
  22. Hi Tom and others Finally dodged the clouds last night an took pics of M13 45 secs f6.3 & Jupiter 1/50 sec f6.3, not stacked , with my Canon 350D and was quite pleased with the results. Will try others when the clouds roll back again. Thanks all for your advice. Robin
  23. Just received a Solar Filter to fit over the Telrad finder glass for locating the Sun. Tried it today and it works great saw 3 sun spots ( my first time at looking at the Sun). island Eyepiece Ltd were very helpful and only charged me the local shipping charge. Super piece of equipment which I was unable to locate in the UK. Their website is http://www.islandeyepiece.com Robin Still waiting for the clouds to go away.
  24. Hi Can anyone recommend a stacking software such as Registax which will work on MAC OSX 10.3 That is without me installing Virtual PC onto my computer. Robin
  25. Hi I'm Robin, have been in to Astonomy for 1 year and have just treated myself to a Celestron 8i Secial Edition. Most impressed with the results. I have a Canon 350d and want use it taking shots of Planets, Moon etc but am totally green to what to do. I have a T Ring, T Adaptor and have ordered a piggy back bracket. How do I go about it. What exposures do I give , what speeds etc etc. Is there a book for beginners to Astrophotograpy that I can buy in the UK. The mind boggles !!
