  1. I'm having almost exactly the same problem with a 127mm Apo triplet. I've got dew heaters on the main objective and on the reducer and yet whatever I have in the optical train, .7 reducer/2" starlight filter wheel/269C Pro or .8 reducer/ZWO 1.25" filter wheel/183C Pro, I get the same really obvious rings in my images. It's driving me mad. I'll be following this to see if someone has any ideas.
  2. Sorry for late replies. Thank you for the kind comments. @Sidecontrol Orion was two sets. 60@60sec and 30@120sec. So an hour altogether. Stacked in DSS separately the stretched before combining in Photoshop. The others were usually 3 minute subs with a L-Pro filter. @teoria_del_big_bang Lol. I know right? I've managed only two imaging sessions this year. But I live in perpetual hope.
  3. Some recent captures. The latest being an hour and a half on Orion from bortle 8 skies. Frooby
  4. Hi. I've not posted anything for a while and I have hit a couple or three targets in the meantime. I don't have lot of data on them yet, especially M33, but I like to post "the story so far" images so I can see if I've improved them over time. Without further ado, here's 5.3 hours on the Elephant's Trunk with a tri-band, 2 hours on M33 in RGB and about 30 mins on Pleiades in RGB. Lots more work do to. All shot through an 80mm Celestron Apo into a 183C TEC, through an LPF and .8 reducer with APT. Mounted on an EQ6R and guided by Altair Astro's guidecam package in PHD.
  5. Hi all After weeks and weeks of cloud it finally cleared for me on Saturday night/Sunday morning. I knew I only had a few hours of imaging available before the target disappeared over my house. I managed to get 1h 20 min of RGB and 1h hour 20 min of tri-band. I know this isn't a lot of data, but it's a start. Shot 2 min exposures at 400 gain at -15c with a 183C. 30 mins worth of darks and flats. Stacked in DSS and fiddled with in PS. I had been planning on getting an EQ6-R in a couple of weeks because I'd been having guiding issues with my ageing CG5, however last night it perfor
  6. Hello again. I have recently had my passion for astrophotography reignited. I can't help but think it might be something to do with being locked in the house for the last three months, but whatever the reason I'm happy to have new challenges. The last time I did it was ten years ago and through the help of the good people on this forum, I managed to get a decent Orion's Nebula and Andromeda. At the time, I was doing everything wrong. No polar alignment, no guiding, using a Newt with no comma corrector and way over my mount's carrying capacity. It's a miracle I managed to shoot anything
  7. I've studied this image before and find it almost beyond imagination. It's truly staggering. And a part of me, can't help but wonder, that if space bends in on itself, will we one day, see our only galaxy deep in the past. Probably not, but it makes you wonder if anyone is looking.
  8. Hi, I just twist the scope. Just be carefull, as you loosen the grips, that the scope can't slide anywhere. I'll often twist it when the scope is level, just to be sure. Regards
  9. Hi, Has the 50D got exposure simulation like the 60D? When I drop the shutter speed right down, stars appear. Also, make sure you're aiming it at a star that you can see naked eye. As mine struggles seeing dim stars, even through an 8 inch. Just a thought. Best Regards
  10. Hi all, Thanks for the kind words and encouragement. I've tried all sorts to add colour, including Anjals How-to. But I'm only getting grey or false colour. It might just be a case of my subs aren't long enough. We've got some clear skies later tonight, so I'll head out again and have another try. Thanks again. Best Regards
  11. Interesting. I was just sat thinking we shouldn't be calling it the speed of light and you explain perfectly, that's it's really space time that sets the limit. Marvellous. So, if my planet was the same distance from the star as our own from Sol, then it would take about 8 minutes for the gravity to cease acting upon it? One thing I find quite frustrating about the universe, is how unknowable it is. All we can ever see of it, is how bits of it were at different points in time. Take M81 for example. We see that how it was 12 million years ago. For all we know, it's been eaten by a massive spac
  12. Hi all, I came up with this question a while ago and have never found a definative answer. So I pose this question here. It's a thought experiment of sorts. I'll set out the apperatus for you. Imagine a single star orbited by a single body. Let's call it a planet. The planet orbits around the sun in an unremarkable fashion and is quite happy. Now, suppose we suddenly remove the star from the system. Does the planet feel the effect of this immediately and start heading of in a straight line? This would mean that information can travel faster than light. Or does the effect take time to reach
  13. Hi, I had a 300D up until christmas. It doesn't have live view and the screen at the back is very small for looking at your pics. I never managed to get it focused with a scope. I now use a 60D, which is awsome in every way I can measure. Live view with zoom. In camera noise reduction, high ISO, 18MP and takes awsome daytime pics too. Obviously if you're trying to keep the budget manageable, it might be something for the future. All in all, I hear good things about the 1000D. Hope you get sorted Frooby
  14. Thanks to this thread I checked my own skies and found them cloud free for a couple of hours. Thank you. I'd have missed that. Regards Frooby
  15. Hi all, Well the skies cleared just enough this evening for me to drag the C8-NGT out to see if I could get the thing to focus with my 60D. It had failed a couple of nights ago and I'd ended up trying to image M42 through a C80-ED, unguided. The results weren't very good, but I was pretty pleased with it, considering it was the first time I'd had a real go at imaging. I mean, you could see it was a nebula of some description. I posted my final image in the other deep sky section by mistake. Much to my joy, I figured out I had to attach the camera directly to the focuser, as opposed to using t
