Quote:You've been doing some fabulous work with the ASI camera for some months now Darryl; and this is icing on the cake! Once my new scope is up and running, I'll be seriously looking at the ASI 120MM largely due to your experiences with it.

Quote:John,You gotta be close to getting the 14" DK, right? I think this camera is going to be a perfect match for it. You'll never need to use a barlow with it. **green with envy**Paul

Quote:Cheerio to this data from me.....leaving for the Murray Mallee right now (and picking up my new laptop glasses on the way!!! )Here's a quick WinJupos combine of the rgb channels using the 4500 frames per channel I spoke about - don't know how it compares and it was pretty rushed to say the least, but here it is anyway for appraisal!
Planetary astronomy and imaging
Quote:All this discussion raises an interesting question (to me at least): If an amateur telescope can capture this detail, might if have been seen by classic visual observers, such as E. E. Barnard, Percival Lowell, or even Steve O'Meara? The 36" Lick refractor used occasionally by Barnard was in an area of good seeing conditions (unlike Yerkes where he later worked). Barnard once observed an occultation of Iapetus by Saturn's ring system and noted (quantitatively) that there were variations in the amount of dimming, presumably due to variations in ring density (presaging the discovery of the hundreds of minor ring gaps). He made this observation with a 12" refractor. Why it it that Barnard never saw the polar vortex feature? Is it possible that the feature did not exist at that time?JimC

Quote:I'd like to find out what optics you use to get 5000mm on the C14. Even my shortest barlow gives me 7200mm. I'd love to get to about 5000 to 6000mm especially imaging Saturn.Paul
Quote:...Also, here's part of Prof. Agustin Sanchez-Lavega's email to me where he refers to his images back in 1991 at Pic du Midi:"Dear Darryl,Thanks a lot for this incredible image. As you mentioned probably is the first one of the hexagon taken by an amateur astronomer.One Saturn year ago (in 1991)! we took Saturn CCD images with the Pic-du-Midi Obs., 1 m telescope that marginally showed the hexagon and the Polar Spot then present. A paper was published in Science (attached)."
