  1. Was a particularly nice view. 1 Transit + 2 moons together about 3 discs away. Got the camera set up and took about 400 frames. A reasonable outcome I think. Anyone else captured the view with 3 moons?
  2. Thank you, this is so hugely helpful in choosing between mono and colour versions!
  3. Stunning! Lovely! You can see both the moon and its shadow! People get hooked up because of such results!
  4. A nice transit tonight, and a beautiful view of GRS. Used to be dimmer back in November, now the colours are back? Happy with the image, was a bit windy for 10fps. But I attach both, the 10fps and 30fps images, not sure which one I like more! PS I wish I could master Registax 6 - it creates final images with artefacts for me, perhaps a buggy build
  5. Hi, a cooled f6 8" Newt exhibits a fairly pronounced triangular-ish doughnut when slightly out of focus on a bright star overhead at 240x. Diffraction rings hardly discernible. The beam of the laser collimator is squarely in the middle of the doughnut on the primary even when rotated around its axis. Is this a case of cell clamps being too tight? Thanks.
  6. That's nice! I'm yet to post my snap, but I only have a small segment of the moon and Jup!
  7. Do I need to be searching this forum for "astigmatism correction"? :-S
  8. Would (the ubiquitous) collimation be a suspect? At high magnification (50x aperture in inches) the stars look like tiny, but oddly shaped polygons (think: an X) rather than points or discs. The out-of-focus seems to be a perfect doughnut, but the diffraction rings are not discernible.
  9. Also, the image stacked in RS5, just can't get anything of similar quality using the Alignpoints in RS6. Trying to follow the AS2/RS6 guides...
  10. Comparing the best Jupiter image caught made of 2000 frames using SPC900 and a 8" Newt to what people achieve using the same equipment there's clearly a huge learning gap! What can I do to get more details visible, such as smaller storms in Jupiter atmosphere? E.g. more precise collimation, replace the mirror/cell/scope/camera/read the manual? Here's a comparison best shot and settings and what other people achieve using SPC900: Mine (8" Newt f6, 2000 10/sec frames, 3x Barlow): http://www.flickr.com/photos/92155443@N02/8376381582/in/photostream/lightbox/ [Philips SPC 900NC PC Camera] Resoluti
  11. E.g. dust/smoke/exhaust particles or jet stream? There seems to be a correlation with the amount of cloud: the more the cloud the better the seeing? http://www.7timer.com/index.php?product=astro&lon=-0.12768310000001293&lat=51.5073346〈=en&tzshift=0
  12. Please don't be discouraged The first time it's totally wow. But then you simply want more
  13. 1200mm and a 2x or 3x Barlow. I want to be able to capture images like this (which are only twice bigger than mine
  14. I see Jupiter being about 100x100 pixels using a 2x Barlow. Here's a recent show. Good. but I think could be much better using a 1024x or higher resolution camera. Would a Canon do a better job? Last year: A few days ago:
