  1. It's very annoying and frustrating, it would seem that not all Canon's suffer with banding, I know some people who have the same camera's as me who do not have the problem, unfortunately both my 1200 & 1300 do. I eventually saved enough money to by a dedicated astro camera, the relief of good quality bandless data was truly uplifting. Since I have sold my ZWO OSC and now have mono and filters I do still use the Canons from time to time for a quick OSC grab, but am quickly reminded of banding. There's plenty of ways to tackle the banding shown in previous comments, and still very good astro
  2. I used Astro pixel processor for stacking, there's a bit of a crop but not much, Here's a single exposure, no crop.
  3. Sorry for late reply, these are single exposures on a static tripod. I have since stacked 22x4 second exposures 135mm lens static tripod
  4. I visited a local boatyard to see and photograph comet Neowise. With a good view to the north it's perfect. This also was my first chance to photograph noctilucent cloud which I have only ever seen once before, so a great night for me I ended up taking 1600 images also making a time-lapse. Camera and lenses, Canon 1300d, stock 55mm & a 135mm f3.5 lens Thanks for looking.
  5. Wow, I have a fairly good image showing this Quasar, superb
  6. Thanks for the info. I must attempt this
  7. The most distant known object I have captured, even further than IC 1101 at a mere 1.04 billion light years distance. Some of you may also have caught this large galaxy without knowing about it. IC 2729 in the Leo triplet of galaxies, near the Hamburger galaxy NGC 3628 1.09 Billion Light years distance. The light captured here left IC 2729 over 900 million years before dinosaurs roamed the Earth. Cheers Nige.
  8. The lum channel was taken with a Canon clip in Ha filter. I layered this with the colour data in Star tools layers module.
  9. Hi Ed. With darks, I recommend a minimum of 22, but more is better. Warm weather always made the banding worse, and darks worked on a small % of images with the bands but not much. To be honest darks didn't do much for my DSLR images as temperature would fluctuate a lot, flats and bias did however but not with bands, Longer subs will make the banding worse unfortunately, but there's several processing options, Star tools has a good banding module which works well most of the time, and a photoshop plugin, Astronomy tools, pretty cheap and works in PhotoShop CR2 free version plu
  10. Hey guys. Star tools is coming along good, with quite a few new tools. Has anyone tried the new 3D module in Star tools. It works very well with nebula, still trying to work out settings for galaxies atm. It's great for FB posts, also 3D glasses or viewing on web browser. Nige.
  11. Hi. The 130PDS is on the absolute limit for this mount so would need to be balanced perfectly. With a good polar alignment and balance you could possibly get 2 minutes. But 60s-90s should be doable at a fair keep rate. A refractor would be a better choice but quite a bit more expensive. Consider re greasing the gears if your handy at taking things apart. I did this with my EQ3 with a good improvement to smoothness of tracking. Good luck and most of all Clear skies.
  12. Thanks & Well spotted Olly. I had not taken flats for NGC891. The circular artefact is the secondary mirror reflection from my 200PDS, which is partly why the black point is clipped Cheers Nige.
