  1. right i see, i have heard of this, but dont know to much. so if this is the case, is there a remedy? Jamie
  2. firstly thanks for the advice. Yes i see what you mean about the f numbers. As much as i'd like to go for the 120 dont think my budget will allow me, so i guess it will have to be the 80. So would the 80 be cabable of taking deep space images as well as planetry?
  3. thanks DP. Yes i would think that as i become more profficent i will be taking longer exposures. So would i be right in thinking that keeping the object centred as you say, that those adjustments are carried out manualy in between exposures?
  4. Can anyone help? Im new to the world of Astronomy and am deciding on which scope to go for. I didnt realise that my equiptment selection was going to be so difficult!!!...but i feel its important i get it right now so that i dont have any regrets later on, down the line!! As i also have a keen interest in imaging i believe that the Skywatcher Evostar 100ED DS-Pro Outfit would certainly be capable of producing some good images. The reason i say this, from what i understand and please correct me if im wrong... for observation purposes a large aperture is key for better viewing. But for imaging aperture size is less important due to the fact when shooting images and the extended length of each exposure (whatever that maybe) more light is captured thus producing a quality image. Furthermore the scope mentioned above is less likely to suffer from halos and coma distortions due to its achromatic and ED lenses. However my question is....given it only has a 100mm aperture, what could i expect to see in terms of observation with the mk1 eyeball and to what detail and clarity? For instance will i be able to focus to a reasonable level of detail on the planets and some deep space objects??? or am i going to end up having to purchase 2 scopes?
  5. Can anyone help??...Im new to the worlds of astronomy and astro photography. So please excuse my ignorance...ive never owned a telescope. Ive just bought the very good book ''Make every Photon Count'', which indeed is very helpful in choosing the right scope for me... which i have decided on the Skywatcher AP ED120 for imaging. However Steve (the auther) talks about purchasing an EQ3 mount to start out with, which of course does not have Goto, so i understand the need for a guide scope. Im thinking about getting an EQ6 as it is a more substantial mount which does have said technology. With this in mind, will i still need a guide scope??
  6. Hi everyone been away for a couple of days so not really been able to keep upto date. Whilst i was away i have been busy snapping away taking wide field shots of Orion...around 200 of them at 32mm at 20sec exposures along with several flasks of tea and lots of jumping up and down to keep warm!! I havent stacked or processed them yet, however at first glance the images appear to be quite good. As far as live view is concerned on my A350...i found that for widefield AP its not really much use. I suspect though that, this is not a flaw with the Sony, rather the resolution is just not high enough on the screen to process the small amount of light emitted from the constelations into a picture on the screen. Either that or given the fact i live in Manchester and the large amount of polution is preventing me from using the screen?? Anyway i ended up using the viewfinder!!! I cant comment on how the live view performs whilst using a scope as i dont yet own one but from what i have learned so far as a newby to the world of astronomy and AP, is that for the purpose of AP im going to invest in a cheap second hand Cannon body then have it moded and keep my Sony for terrestrial photography. I love my Sony and would not trade it for anything, but i have to concede as far as AP goes Cannon seems tolead the way in terms of support and accessories etc. Its also worth pointing out from the research ive carried out that the Cannon seems to perform slightly better in that they dont seem to suffer with ''quite'' as much noise. Though i dont have personal experience of this.
  7. Im a complete novice to the world of AP. Can anyone tell me the ratio of dark images i should take with my DSLR to the number of light images? Do they need to be of the same exposure time? Many thanks
  8. Well...i eventually managed to produce 2 images .....of sorts!!!! Hardly mind blowing though. Bearing in mind, i was using an 18mm wide angle lens on my dslr. First image consists of orions belt and taurus (i think...remember im new to this!!...so i could well be wrong!!) As far as processing goes...there is an awfull lot of pollution!! But knowing what i know (which is next to nothing) i have managed to reduce a lot of it...though it might not seem it!! Help and advice welcome.
  9. Thanks for that Brantuk, i shall look into that :0)
  10. Hi Spikey, Thanks so much for your advice, i really do appreciate it. Was up until 7am trying to figure out what i was doing wrong!! As it happens, i did have '2xdrizzle' enabled, so im going for round 2 tonight and will report back!!...hopefully with better news. I do have quite a bit of data to play with. Ive made the most of the good weather over the last week and spent my evenings outside freezing my socks of taking photos. Lets hope i can produce something half decent.
  11. Thanks guys for your advice, i did indeed enable '2x drizzle'. I shall try it without and report back. Jamie
  12. Can anyone help??? As a newcomer, i was out last night taking some pics of Orion and Taurus. I took 2 sets of ten images with 5 dark shot of equal exposure. Downloaded Deepspacestacker and had a go at stacking...but with no success!!! Grrrr I followed the intructions on DSS website to the 'T'. But as the program goes through its process of stacking the images...i get the message 'Out of Memory' just as its saving the image after the very long process. How annoying is that ??? Anyway, i closed the program, restarted it and opened the autosaved image. To the edit histogram page (with the grey image...which i believ is correct). Managed to produce the right curve in the histogram, but then click apply...and nothing happens!! Can anyone help???? Arghhhh!!! Was up all night until 7am trying to do this!!! Got matchsticks holding my eyes open.
  13. Hi John, Spikey Thanks for your feedback. Was out last night taking some pics of Orion and Taurus. Downloaded Deepspacestacker and had a go at stacking...but with no success!!! Grrrr I followed the intructions on the link you kindly provided me with John and also the instructions on DSS website. But as the program goes through its process of stacking the images...i get the message 'Out of Memory'. How annoying is that ??? Anyway, i closed the program, restarted it and opened the autosaved image. To the edit histogram page (with the grey image...which i believ is correct).

  14. Hi Gina, thats a great image, well done. As i dont own a scope yet im having to make do with just my camera and tripod....seems like a million miles away before i can get mine!!!
  15. Thanks for that John, greatly appreciated. Added that to my favourites and shall try it out.
