    CCD venture

    Finally got my grubby mitts on a CCD camera - and the 'old but new-to-me' atik 16HR is giving some good results. Teaching myself basic narrowband imaging/processing techniques. NGC6888 Crescent ne bu.tif
  2. Yeah, i have read quite a number of reports online of persistent halo's with the baader AND astronomik after the apparent time period where they recalled products and resolved the problem. Anyhow, i bought the baader 2" OIII 8.5 and it seems to be almost halo-free - i've noticed one or two larger brighter stars with mild halo (see image). the bright star near the center top shows what might be a halo - (its only in the OIII subs) I do have an old CCD - a meade DSI with the grid passive cooling on the back. But also i have been using my filter-removed 350D with some success doing narrowband imaging, mostly Ha and OIII as i've yet to get a SII filter. Here are some examples from the 350D and astronomik 12nm ha clip and skywatcher visual OIII filters (ED80 scope) They aren't CCD quality but I personally like them enough to think it IS worth trying with a DSLR Thank you for the replies to the original post.
  3. Yeah, i'm definitely liking the baader OIII - they look good on paper, and plenty of decent images around. Thanks for your feedback,
  4. Hi there, I'm hoping to buy an OIII filter for astro-imaging and i've read a lot of halo related posts and am unsure which to go for. Are the Baader OIII now halo-free? it sounds like OIII are notorious in general for halos and i want to be reasonably sure before i hand any money over. My astronomik ha 1.25" shows bad haloes, but the clip version doesn't although that one is newer. Will the astronomik OIII clip be halo-free? I am unable to reach the budget necessary for Astrodon, so i'm thinking the next best will be either Baader or Astronomik, is this pretty accurate or am i missing a manufacturer? Many thanks for any assistance in advance!
  5. Was looking for info on a decent OIII filter for imaging and found this thread - the title says oiii for imaging, but seems mostly related to DSLR so i thought i'd post my own results using a DSLR for narrowband. As a rough idea to anyone thinking of doing it. Here is a Ha + OIII bi-colour image of the VEIL NEBULA taken with an ED80 and a modded 350D (filter removed, not mono though) using astronomik 12nm h-alpha clip, and a cheap skywatcher visual OIII 2" filter. and a h-alpha only mosaic of the north america nebula - 2 panes, with just the red channel extracted, using ED80/350D astronomik ha clip. and a mix of OSC RGB data from the 350D and a h-alpha stacked and layered as luminosity in photoshop to add contrast and improve detail. Rosette and Bubble nebula.
  6. Got these crater shots a few weeks before that, quite pleased with the detail despite the soft appearance from mediocre seeing conditions. If i recall rightly it was using a 5xpowermate as well which pushed the scope past its useful limit. I could be wrong and it was just my 3 x barlow. So dont quote me on it - i did however manage to get a useable image that way at one point, so its always worth trying if the conditions allow. 3rd crater.tif
  7. Thank you Putaendo Patrick. Yeah, the good kinda outweighs the bad i always find in astronomy, its worth the hassle when it all comes together one night and you get an image you are happy with.
  8. Well i reckon it looks amazing, even without the star shrinkage Really lovely image Graem, well done.
  9. Found an old (apparently USA model) celestron C8 SCT a while back, its a bit hit n miss with collimation and the optics - (some very strange star test shapes :P) but when it works it works well Here is a couple images from a couple months back. Thanks for looking. This particular night seeing was reasonably good, and collimation wasn't too bad either. Celestron C8 / ASI120MC / 2X barlow - captured in sharpcap2, stacked in autostakkert!2, wavelets in registax6
  10. Definitely yeah, the seeing and other issues all get magnified as well. You'll find that has a great deal of influence over how well you can view planets or image them - along with collimation and quality of optics, the astronomical seeing is what determines the amount of detail in an image of a planet, and i think of the view in the eyepiece as well. Sometimes when the seeing is bad, you might end up getting a better view with less magnification for the same reason, and with smaller scopes - aperture in particular - too much power will have a negative effect if you push past the max. useful magnification.
  11. Yes, a barlow will increase the focal length of your scope - visually or photographically - effectively raising magnification and making the object look bigger, or appear bigger onscreen (if using a camera).

    The next step.

    Almost a year since beginning Astronomy.
  13. Have to add my m27 taken with the orion g3 colour, i kinda added negative comments quick enough so i thought i'd add a positive here's one of the more successful results from the g3 and ED80 scope

    No longer a newbie :)
  15. Wow! Those are very good pictures from the entry level CCD. Very impressed especially with the whirlpool Galaxy - I think using the monochrome camera will help a lot as it was the software debayer process as well as the weird colour tones that made the G3 difficult to get good results from :/ with the mono + filters you avoid debayering and have control over colour balance in the final image. But well done getting those images posted above, really good to see nice results from the G3. Hope more are to come
