  2. California nebula

    Wow, that resolution (fine detail) is incredible. Ray
  3. Veil and Pickering

    Geeeeesuuuuzzz!!!! Lovely remnant Professor. You really catch some faint wispy detail that lingers out there. Ray
  4. California nebula

    And to finish off the day I processed the DSS2 data for the California nebula and got this result Greg
  5. Veil and Pickering

    Another grey day so playing on the computer time. This is Sky90 data combined with DSS data for the Witch's Broom nebula and Pickering's Triangle. Greg
  6. The stars like dust

    As I stare at that, it reminds me of a birds eye view of a phospholipid bilayer (don't ask, science is a rabbit hole). Ray
  7. The stars like dust

    Here's a bigger bit to drool over Greg
  8. The stars like dust

    Incredible Prof. To think we only see a small amount of our galaxy's stars. Astronomy is pretty cool Ray
  9. The stars like dust

    I was checking out an old 200mm lens image of the Caph region and when I zoomed right in to see individual stars I realised I hadn't seen an image like this before. So here, for you to see "The stars like dust" is a highly cropped region in Cassiopeia Greg
  10. Out until 3 a.m.

    The idea is WAY better than the reality Ray. I find it very difficult (typical male can't multitask). Greg
  11. Out until 3 a.m.

    The spikes look epic. I love the idea of two domes running at the same time. Ray
  12. Out until 3 a.m.

    They look red enough to be Carbon stars but they're not. North Dome now also sorted Here's a crop to square and add some star spikes version. Greg
  13. Out until 3 a.m.

    Loads of detail. Didn't spot the asterism, it doesn't really 'pop' out unless I cross my eyes, rub my belly and pat my head....Looks like the South dome is pretty well sorted. Well done. It's been so long since I did any LEA, I doubt I even remember how. Is that a couple of carbon stars just of center toward the top of the image? Good luck with the North dome! Tim
  14. Out until 3 a.m.

    Did you spot the 3 asterism??
  15. Out until 3 a.m.

  16. Out until 3 a.m.

    A beautiful (extremely rare) clear and Moonless night last night - so I was out until 3:00 a.m. this morning Two jobs on the go, Hyperstar imaging the Pleiades in the South Dome, and polar aligning and setting up in the North Dome. I will start with the North Dome antics. I am using Sharpcap for polar aligning and it was less than a 30-minute job to get "Excellent" alignment in the South Dome. In the North Dome it was giving me nothing but trouble. Last night I actually packed up and gave in before pulling myself together and going out again to sort the bastard out. At some times I would get plate solved, at other times I would get intermittent plate solving, and at yet other times the bloody thing would not plate solve AT ALL. By times I really should say ANGLES. So what was happening? Like an idiot I have 2 apple trees too close to the observatory in the North, no problem with stuff to the North, unless of course you need to see Polaris for Sharpcap polar alignment. Still no great problem, all I have to do is take the top off the apple trees and I'll still see Polaris OK as it is well above the roof of the house. So a couple of weeks back I took the top off both apple trees and thought everything was O.K. But I see in the cold light of day, that I didn't take enough off the top of one of the trees, and it was at that angle (of the mount) that the polar aligning plate solving was failing. Well in the end I managed to work around the offending branches and finally got "Excellent" polar alignment - PHEW! Whilst I was playing these games in the North Dome I was imaging the Pleiades in the South Dome with the Hyperstar 4. The image shows 27 x 3-minute subs with the HS4. The result is VERY interesting. It is NOT perticularly deep, but it is EXACTLY the depth I would expect from (the equivalent) 15-minute subs from the Sky90s. Now it took 1-hour exposures from the Sky90s to show the Taurus molecular clouds in the region which equates to 12-minute subs on the Hyperstar 4. So the final experiment I am going to do on the HS 4 to finally bring this all together in a way I can understand, will be to take 5, 10 and 15-minute subs with the HS 4 and check out the resulting depth of the images. I'm pretty sure I know what I'm going to see - but it would be great if the experiment confirms. One massive bonus from this HS4 - no ghost flares from bright stars!! Yipeeeeee!!!!! Greg
  17. The Celestial Pole

    No I did a negative B&W of a colour image to make it look more scientific Greg
  18. The Celestial Pole

    You could do some good star trails with that setup. It has a decent field of view and seems to be quite sensitive as well. However I take it that the above image is a monochrome camera? Ray
  19. The Celestial Pole

    What a great idea!!!! Greg
  20. The Celestial Pole

    Very nice Prof. Be interesting to turn the mount off for a minute and watch the circular drift to pinpoint the exact pole. Ray
  21. The Celestial Pole

    The bright star is Polaris and the centre of the image should be the Celestial Pole (North). Greg
  22. The Celestial Pole

    I used Sharpcap Pro to get the Hyperstar 4 C11 on a wedge rig Polar Aligned. I cannot sing it praises highly enough. It is a BRILLIANT piece of software. If I can get a piece of crap mount within 10 arcseconds of the Pole, then anyone with a half decent mount can do better. Anyway - after Polar Aligning I just left the scope pointing where it was and got 14 x 3-minute subs with an almost full Moon out. Greg
  23. Andromeda

    48 minutes of data? Gotta love that Professor! You don't need to go any deeper. P.S It might be the Universe, but statistically speaking, you could still run out of objects to shoot with those fast optics. Ray
  24. Andromeda

    And here is Andromeda on the 2600MC with the new colour settings. This is a poorly process of 16 subs at 3-minutes per sub. Greg
  25. Pelican with new settings

    I am using MaximDL 5 as well Ray. Under colour conversion there are scaling factors for Red, Green and Blue. The defaults seem to be Red 100%, Green 80%, and Blue 100%. If you reduce the Green to 60% the colour comes out right. I have redone the link Greg
  26. Pelican with new settings

    Interesting Prof. I'll have to try this. I have a few RGB and NB images where the green is overpowering. I have a few tools to reduce the green already, but I rarely use Maxim's enhancement features because they are fiddly (though I am using an older version of Maxim - Maxim DL5) P.S that link is not working.
