  1. The short exposures were not guided, i was taking short test shots to make sure I had the target in view. There was more than 1 image that had trailing and I was stood away from the scope. I also had it with some of the 3 minute exposures. Could they all be because of cables hanging down? Does the fact I had a mix of good and bad point to a tracking issue or make it less likely? Thanks
  2. Can anyone shed some light on what might be causing the trailing stars even at short exposures of 20 seconds? Here's 2 images from the beehive cluster, 1 showing trails at 30 secs and another which looks ok at 3 mins. Seems to be intermittent. Grateful for some help Thanks
  3. 2 hours ago, drumsolo said: Hoping someone can help me work out what is going on with my HEQ5 Pro mount. Set up last night and I keep getting the same problem, trailing stars even without guiding and taking a 20 sec exposure! Never had problems like this, my Polar alignment was within 3 degrees. It seemed worse when I was pointed south towards the beehive cluster for example but weirdly I did manage to get some good exposures of the same target when guiding for 3 minutes! Seems a bit random. Here's the images, a 20 sec exposure showing the trails and a longer one with no real issues. could this simply be the cables trailing and causing some drag as I didn't loop them up? I also moved the mount with out the weights on a couple months back and had a horrible crunching sound. Could it be Gear problems? Thanks Stuart
  4. That scope is packaged with the heq5, has worked fine for last 10 years. No breeze.

  6. Anyone had issues installing PHD2? My install just hangs on extracting files message. Have tried earlier versions but same problem. Never seen this with any software. Thanks Stuart
  7. Hi does anyone use sharpcap with orion starshoot autoguider? I have tried installing latest driver and ascom driver from Orion website but sharcap doesn't detect it. Any ideas? Thanks Stuart
  8. Sorry I don't know what you mean, can you explain? Thanks
  9. Could the star trails be coma? I am using a skywatcher coma corrector with LP filter on the top.
  10. Why not? I have just come back after 5 years so am not up to speed with latest software! What's the big difference? PHD1 always worked well in the past for me.
  11. I use PHD 1, is that info still available?
  12. Here is the full image. I ae PHD guiding didn't see any errors. Never had a problem before guding, Im not sure what you mean about RA oscillation or where i would find it?
  13. Hi all, I took pics of m51 the other night and was guiding. Took 2 and 4 min exposures but all are showing star tails. Does this point to polar alignment or something else? Many thanks Stuart
  14. Thank ill take a look. I dont know where to start as this is a new area for me. Would you say your images have improved significantly to justify the extra price?) Would i need an adapter for a skywatcher 200p?
  15. Hi looking for recommendations to replace my unmodded canon 1100d with a OSC. Looking to spend around £1000k, can I expect significant improvement over the canon for DSOs? I use a skywatcher 200p, my skies are fairly dark but having some LP over to the north east. Grateful for advice and any experience of users of OSC after moving from a DSLR. Thanks guys Stuart
  16. Hi fellow star gazers. I have come back to this magnificent hobby after several years away. Can't believe I have stayed away so long as I am hooked again. Anyway this is my first proper attempt at M51 with my Canon 1100D unmodified. I took around 20 x 4 min exposures, 20 flats, darks and 30 x bias. Stacked in DSS and processed in photoshop. That's where I have struggled, this seems to be about my limit with what I can do but I am wondering if it can be processed better or do I need more data? Struggling with noise so any tips on reducing would be greatly appreciated. I used levels and curves carefully, sharpened slightly, played with saturation and colour balance. That's the limit of my knowledge. I haven't removed gradient as I don't know how to, help again appreciated. Scope is skywatcher 200P, HEQ5 Pro, guided with PHD, LDAP light filter and sky watcher coma corrector Thanks in advance Stuart
  17. Thank you so much for your advice, I will take the cover off and have a look. If the gears are binding then I assume I can buy replacements gears? What do you mean by backlash? Never heard about 'Motorfocus', is that something I can replace on my sky watcher 200P? Thanks again
  18. Also when i was guiding use orion starshoot and PHD the picture from the starshoot started showing trails rather than round stars , does this also point to mount gear problems?
  19. I am worried that I may have damaged the mount gears as when I was setting up I forgot to put the weights on before I slewed the scope and it made a horrible crunching sound. Can the gears be replaced if they are damaged?
  20. Hi guys, I have returned to this magnificent hobby after 5 years and hoped to pick up where I left of although it seems I had forgotten a lot! Anyway I took some pics of Orion Nebula the other night and managed to get my auto guider working as well. I took 4 minute subs but the results are disappointing, they wouldn't stack in DSS and look blurry to me. I did use a Bhatinov mask to focus on a star first before imaging. Does this image look like a focus issue or tracking or both as the stars down the bottom looked like trailing slightly. I also used a coma corrector with an IDAP LP firer, could this combo have caused any issues? Grateful for assistance to as I really want to get imaging again to a good standard. Thanks! Stuart
  21. Ok so do you save your position and then Park the scope? Then power on the next night and start from Park and go to user defined object? thanks again stuart
  22. Thank you Stargeeezer Tim for your advice. Whilst I appreciate the other comments these have just confused me even more. How do you save your position on synscan? yes I agree consecutive clear nights is asking a bit much!!
  23. Hi sorry if this has been asked before but I can't find all the answers I need. My current imaging setup is SW200pds on HEQ5 pro autoguding and imaging with a canon DSLR. I want to try imaging over multiple nights to get more data and hopefully better images. I have never tried this so my question is if I leave my camera attached to the scope in the same orientation how do I re align the scope the next night if I am not using an eye piece to find the alignment stars? Am i simply using the camera live view instead of the eyepiece? Could I in theory leave my scope powered up all night continually tracking so it doesnt need re aligning? If I parked the scope can I resume from Park position after turning the power off and it will still be aligned? Sorry if these are dumb questions, I'm just trying to find the simplest way of doing this! Thanks in advance Stuart
  24. Hi Michael, Thanks for pointing this out I wasnt aware of this issue. It is never straight forward! Would the vingetting be much worse than using my aps-c sensor? Assuming I can remove this by taking flats? Thanks Stuart
  25. I'm currently using a 2" Skywatcher LP filter with my canon 1100d. Would I see a vast improvement if I upgraded to one of the Astronomik CLS Clip filters instead? The price increase would suggest yes,has anyone any experience of these filters? thanks
