  1. Thanks Chris, steps 1 and 2 I'm already doing. The scope was out for a good 2 hours, before set up and collimation. I think like you that its step 3 that's going to be the issue! Waiting for a good steady night where the seeing allows for precise collimation!!! Still I was hoping that there is a trick or something I have missed in Metaguide..! Changing the frame rate to 30 frames/s seem the slow the "red dot" down a bit... just a bit!!!
  2. Hi Neil P, Well your the master of the planets here, so I need your advise to push the scope harder! I did have a 2x barlow from WO but it wasn't very satisfactory, even though it claimed to be an APO, so I sold it!!! Anyway, the ExtQ works as advertised so what barlow lens would you recommend beyond the TV-Powermates? The other piece of the puzzle is collimation, although I'm confident that its 95% bang-on, I'm currently trying to push for that last bit of performance using "Metaguide" but here I'm also a novice at present???
  3. I thought about using an artificial star since my seeing conditions are never really good enough to collimate on an actual star but you still need to put these things some 60m away from the scope??? And I just don't of the space or line of sign to be able to do it... are well!!! Hence, I'm just now experimenting with Metaguide which performs some stacking / averaging of the stars centroid (or peak) to allow collimation? I'm just a beginner with this method also looking for further advise but it does seem to work, sort of???
  4. A big thank you to everyone who commented on my Onion ringing problem because its now solved , great! I think the decisive fact was the Gamma needed to be at 100 or greater. At approximately 02:30 I managed to get this set of Jupiter images using the modified Mewlon M250S (CR Baffle added) and the DMK21 with the correct settings!!! They are only mono, taken using and IR-Pass filter; one day I will invest in a manual filter wheel and the necessary RGB filters but for now I'm very happy with the results. Still need some advise; As anyone used Metaguide? I'm trying to use this for collimation of the scope? I have read the manual and I think collimation is bang-on but want to push to get that last bit of perfection!!! Problem was that the "red dot" was moving around too much. Very close to the centre of the star and not too far away but perhaps I could have got a better result with a better technique??? Anyway, I hope that you like the images Most probably seeing conditions were the limiting factor
  5. Very nice... I prefer the Mak-Newt images, perhaps on a better night the C11 would win out!
  6. Looks to be a very promising start... can't wait to see more of this object. I have never seen it for my location, its just too low down... are well, never mind.
  7. Amazing Peter... you must have the Patience of a Saint!!! I can only imagine the effort!!!
  8. Wow...now that is an epic image... 22 hours and all with a DSLR, great.
  9. Very, very nice set of images, it seems like everyone is stepping up their game this year!!!
  10. No, I'm just using the factory fitted wavelets in Registax; I haven't applied any other deconvolution routines...
  11. That looks excellent... Better than Damian Peach since your is taken in the UK not some exotic place like the Bahamas!!!
  12. Gamma was set at about 93% so you might be right!!! Why does it happen, do you know? Or is it just one of those things!!!
  13. Can't remember precisely where it was set? Sorry but will check next time... probably the weekend! If the clouds shift?
  14. Stunning detail and a very nice capture, great. More info regarding the camera please?
  15. Who's eyepiece projection system do you use? Very nice capture by the way...
  16. Its not going to win any awards etc... but here is Jupiter from the 14/10/2012. Imaging scope was my Mewlon M250S CR. I added the new CR baffle tube this weekend, so this is a test image to prove everything was working correctly after the installation. Collimation was rechecked but maybe a out by a hair! nothing significant. Seeing was crappy, but as I said I wanted to test the CR baffle. Imaging camera is a DMK21 and the gain was around 700 - 800 when I remember correctly . IR pass filter fitted to the camera. It was about 05:30 in the morning so Jupiter was high in the sky. Its also the boring side of Jupiter but the ringing is clearly evident for all to see!!! With a little bit of de-noise / de-ringing but I'd sooner rather get rid of this at the capture stage if that's where the issue lies?
  17. Hi Guy's, sorry and Ladies!!! I need a little help here? What causes the ringing effect around the planet? I'm processing the AVI using Registax 6 in the usual manner, the final step being the wavelet sharpening and it is at this point that I start to get a ring around the outside of the planet and inside the disk of the planet? Is this a stacking artefact or a problem with the wavelet sharpening?
  18. Wow... thats going to be a cracker! Can't wait to see the colour image!
  19. Very nice but the background looks a little clipped?
  20. Second version is looking great... maybe a little bit pushed to hard? Try using the star mask function and a little "Morphologicaltransformation" of the brighter stars in PI.
