  1. Hi all, Been trying to find surveys to use in a light pollution analysis sheet i have to complete. help would be appreciated. seb x
  2. again been looking around the internet for this one have no idea how to answer it. O type stars in a faint galaxy are observed to be magntiude 15. Estimate the distance to this galaxy. seb xx
  3. Okay all apparently its the 30 inch Schmidt camera at St andrews University - The James Gregory one.
  4. honestly been rummaging around the internet for this one. are there even any? this odesn't include jodrell bank of course. seb xx
  5. alright but i know other people image with this particular filter and DSLR. Is it to do with the telescope?
  6. I usually use this method but the point is I'm using a filter which is sized 1 25. x
  7. Hi all, Have a problem with focusing my Canon 1100D connected to a sky watcher newtonian via a 1 25 adapter with a baader uhc filter in it. Optimal focus is a lot closer to the telescope than I can go, so was just wondering how I can fix this. cheers x
  8. brilliant picture. Where was this taken?
  9. Rosette nebula also could be an option - had decent success with it with an unmodified camera from London. Interesting about the North America nebula Wim - Tried this target out but found it hard due to the faintness and how spread out it is. I will definitely try it again this spring - now that I have a modded camera - fingers crossed with darker skies.
  10. From the album: Imaging Challenge #15 - The Milky Way - Now Closed

    Milky way in B&W in San Lawrenz, Malta - some stunning skies there this summer and the bonus of seeing the lunar eclipse! Canon EOS 60D, roughly about forty thirty second exposures. Stacked using DSS, altered colour with windows pics Taken 9th August.
  11. Hey there. Is this your first time entering into astronomy/astrophotography? Have you started by doing any observing with a previous telescope? Venturing into deep sky astrophotography can be hugely rewarding but taking the correct and careful steps will make life so much easier in the long run. I don't want to sound patronising in any way but do you have a clear area where you can set up this scope in order to take photographs? Do you have an apropriate place to store the telescope? Will moving house be an possible/probable option in the long run? Do you have a suitable computer which can handle deep sky imagery? Have you accounted for the possible cost of deep sky processing software? Do you have the time to take these images? I'm only sharing these with you because some of these were problems I encountered when I got bitten by the astronomy bug and caused unnecessary hassle. I started astronomy with a small telescope, then gradually selling off my old equipment and buying new kit until I got where I am now. Jumping into the deep end with no previous experience can be a very steep learning curve. I understand how you want to get straight into it with a big telescope but it can be dangerous financially and making a significant investment into a good telescope/mount and and then getting little use out of it. Anyway, just a bit of advice. Deep sky astrophotography is one of the most satisfying hobbies in my opinion! Hope you find the right telescope for you whatever the approach. Seb
  12. Hey kids, I've had 1372 notifications on opening today - a sign of how little of I've been using this forum as of late. Planning to do some imaging of the Elephant Trunk today and hopefully share it with you guys. To get right into it, this an image I haven't shared with you guys. It was taken in mid-December in my backyard in the centre of London. Really would appreciate any tips for this as it's far from perfect (not much detail whatsoever) and if I were to revisit this target I would definitely add more subs in. Workflow was in startools. Canon 1100D, ISO 800 roughly an hr of total exposure, other equipment used apart from camera is in signature.
  13. Hi all,of UHC filter I was wondering about the availability which clip on or attach to canon cameras. Sky Watcher do some but I discovered that they are suitable only for eyepieces. Thanks, Seb
  14. Hi all, This isn't the first time I've had this problem. I have about 50 of these and then I get that. I'm assuming it could be to do with alignment or poor data but I have had decent results with similar photos so I am clueless. Autosave001.tif
  15. Hi all, My 10 images of the milky way taken with a tracking mount - EQ3 pro - turns out to be extremely blurry. I've tried every single main option (Stacking settings > Lights > median, average, kappa sigma clipping) and (stacking settings > result > mosaic, standard). I'm using 3.3.4. I've examined my data but it seems to be fine. The mount moves a bit but not drastically and I've experimented with worse data and got better results than this. I'll attach the raw and the .tif files here. The output is unlike anything I've seen before which does make me wonder...

  16. Hi all, I was surprised and chuffed to see my International Astronomy Photograph of the Year Orion Nebula image all over the press! I submitted it and didn't expect it to go this far. I am delighted! http://www.telegraph.co.uk/science/2017/07/25/insight-astronomy-photographer-year-2017-shortlist/orions-gaseous-nebula-sebastien-grech-uk-lying-1300-light-years/ http://www.ibtimes.co.uk/21-spectacular-images-2017-insight-astronomy-photographer-year-shortlist-1632048 http://www.standard.co.uk/lifestyle/london-life/insight-astronomy-photographer-of-the-year-2017-stunning-pictures-of-shortlist-revealed-a3596276.html#gallery (19/21 for this link) Sebastien
  17. Great image. It has a simplicity about it which I love - different from some other images, which really pop out at you. The subtle beauty reminds us how small we are. Fantastic entry. Seb
  18. Hi all, These are my first robotic scope images taken with I telescope in Australia. It is nice to have a variety of objects so I enjoyed imaging southern hemisphere targets. The dense stars and gases in the milky way are simply gorgeous to look at. Here are the few I have managed to capture so far with 90mm refractor in color. Seb M16 IC 4684 M8 M7
  19. Hi there, Just wondering if any of these are still for sale. I'm interested in the sigma 70-300mm lens - would you be willing to sell each piece of equipment separately? If so how much for? And would the lens fit into an EOS 60D? Thanks, Seb
  20. I am going to South West Cornwall in a few days time and I am going to bring my widefield setup with me (the scope is too big). But after looking for targets, I can't find anything which will bring out some nice detail. I was thinking about V2 Johnson but I suppose that is too faint. Thanks Seb
  21. Very nice , lots of gaseous detail in the spiral arms. It's actually M101 - the pinwheel galaxy.
