  1. Greetings all, Probably a frequently asked question here but I've had a look through several threads and can't see what I'm looking for. Basically, I'm in the market for a laptop and I'm wondering what are the basic requirements, processor speeds, ram, and hard drive storage etc to enjoy astrophotography. I am still a newbie at present my needs are collecting my subs, stacking them in DSS and then processing in gimp. I would like to future proof myself for when I will need video capture for planetary work, driving a mount/polar alignment, focus etc etc. And it goes without saying.....but I'm on a fairly tight budget! Up until now I have been using my wife's Mac book air.....but apple is driving me insane ! And correct me if I'm mistaken but a lot of programs used by astrophoto graphers seem to be windows based? All suggestions are most welcomed. I would also point out that while I can find my way around a computer with a minor degree of competency I am most certainly not a computer expert by any stretch. Thanks in advance. Andy
  2. I was going to ask whether you had a Barlow attached to get this image.....presumably a 3X Barlow will make the image of Jupiter a lot larger in the frame?
  3. Thanks for all of the valuable info guys. I'm definitely not a handy man so I will probably be lazy and get the charger/compressor type pack and then there's no room for error!! This really is a goldmine site for us thanks, and clear skies !! Andy
  4. Thanks guys....awesome the 'tip positive' on the power requirements is nothing to bother with? I don't know what it means.....however it looks like the car battery is the way to go 👍
  5. I am very ignorant when it comes to things electronic. My basic question a Meade type portable battery power source pack suitable for a skywatcher synscan alt AZ mount?.....the synscan instructions mention odd sounding amps etc and I don't want to blow a gasket in my mount ! ....all advice gratefully received. Andy
  6. excellent image.....very cleverly done and wonderfully aesthetically pleasing !
  7. did you manage to remove all the faults in my picture?....was that with pixinsight?
  8. thanks Bobro.....I haven't quite made the leap to flats yet.....better get learning pronto !!......that's a massive improvement though.....thanks heaps
  9. Here is my processed image that I refer to above. As you can see.....a good collection of vignetting and gradient. Any suggestions on how to improve it would be gratefully received. Despite my whinging......this is my best image to date and gives me a little smile every time I open it
  10. Many thanks Bobro for these suggestions. I am heartened to see that your tips for DSS are what I am doing ! Thanks for the top tip re dropbox. I was thinking that I could convert these pics to jpeg but could someone process the DSS image as a jpeg? I would have thought a lot of the info would have been lost? but i'm a fair technophobe so its outside my knowledge.
  11. Greetings to you all, I am begging some expertise and assistance (again!!) I managed to get 35 minutes on orion last night and have successfully stacked in DSS. My issues seem to start in processing. I was hoping to see a 'flame' coloured flame nebula but it stubbornly stays red which may simply be down to not enough time at the camera....dew was the issue (late autumn here) and i haven't figured out how to process images from different nights imaging) Anyhow, i have posted here my attempt at processing (gimp) and also the original DSS file in the hope that some of you may be able to apply your expertise and see if you can't make it look more pleasing......and also help me by explaining how you did it! Also, I would really like to know where you think I've gone wrong on my processing.....have I over/under cooked it etc. As ever I am most grateful for any assistance.......processing is a tough nut to crack! Thanks in advance all of you and below are the technicals. Seeing was a bit misty and orion was low to the western horizon. yes, its upside down.....i'm down under! canon 40D modified, 135mm, f5, ISO 1600 skywatcher star adventurer 18x120seconds lights 18x120seconds darks 20x8000/sec bias stacked in DSS Ok.....strike this one.....after spending an hour and a half uploading 61mb's somehow totally failed to post them permission to swear loudly !!
  12. Many thanks Jannis, i didn't realise that I might actually be removing data !! i will follow your suggestions. It's a steep learning curve alright.....the more I learn the more I realise I know next to nothing. Im really enjoying the challenge though. i also may have not made it clear in my post but the image was taken with the lens set at 200mm ......I am still interested in wide angle at the moment but thought I would have some fun with it and I have to say I'm very impressed. auto tracker is now on santas list 😀 Cheers, andy
  13. Also, may notice that I put a photo up in the deep sky imaging section and its annotated. Unfortunately my version of gimp doesn't offer the Lucida calligraphy.....but I've used something not dissimilar. Cheers, andy
  14. Thanks for your replies .....I think it helps that I am lucky enough to live in a place with very dark skies. I'm afraid I've been bitten by the bug now........goodbye bank balance !!
  15. Thanks Luke for your reply. i have to say that I quite like the swirly fonts ...... I should say typeface ! 😀 I find them aesthetically pleasing......but I do like the typeface that you suggested also. cheers, andy
