  1. Thanks for the comments. The sketch is done with a series of watercolour washes on a faint pencil outline. MD
  2. Not managed to post any images or sketches for a while so here's one. Image of main crater, top left, Theophilus, Madler to the right and below craters Cyrillus F, Beaumont and the flooded crater Fracastorius. The small crater in the Mare Nectaris is Rosse. North to the top. UT 2030 15.08.2010. New Zealand. MD
  3. Great set of images Nick - just shows what a difference a day makes. The last one is very dynamic with the sun just catching the central peaks in a couple of small craters. MD
  4. I've just upgraded mine using a 12v 17 amp battery. No problem. The handset should only draw the current it needs - i.e. 100ma. MD
  5. Excellent capture Paul - nice tight stars. MD
  6. That's an excellent Cent A Sam.You got much more detail than the one I did a month ago. Well done. The skies down here have been great for quite a while now haven't they? The darker nights certainly help. MD
  7. A real improvement on the previous post Steve. Good colour and detail. Well done John
  8. Thanks for the comments - glad to be able to supply images from 'down under'! Just noticed I said the ED80 was @ F4.8 - it should have been at the standard F7.5. John
  9. Wide field Centaurus A from New Zealand Just over 1 hour of data in 120, 180 and 240 secs subs. ED80 @ F4.8 Atik 16 HRC. Centaurus A is Mag 7.0 and 18' wide. It's also an incredible 15 million light years away. John
  10. Still trying to set up the astro equipment in New Zealand, but here's one from last night of Eta Carinae. ED80 @ F4.8, Atik 16HRC, 5 x 240 secs, 10 x 180secs. EC is very large - 120' overall and bright at Mag 1.0. In comparision the Orion Nebula is 85' x 60' and Mag 3.7 John
  11. Olly - the little WO certainly tries it's best to keep up with the big boys, doesn't it? I want to try OC with the C8 @ F6.3 and the DSLR and see if I can improve on the ZS66 image. It's half the arcsec/pix so I should get better resolution - and more stars! John
  12. Thanks for the comments guys. OC is certainly a whopper - slightly larger than the full moon visually. As it's rotating pretty quickly the shape is slightly out-of-round. You can also see the stars to the core - unlike the second largest glob in the sky 47 Tucanae. This isn't well placed for me at the moment but I'll give it a go when it is. John
  13. Just getting my gear set up in New Zealand. First guiding session with 7 x 120 secs subs Atik 16HRC WO ZS66 F5.9. John
  14. Hi Sam Didn't realise you'd got back to NZ. Great report. I've been here since before Christmas. I'm resident in NZ now. Brought all my astro gear over with me. Done quite a few tours of the Southern skies looking at the same objects as in your report. Roll on the longer, darker nights eh! MD
  15. Hi Alexxx I have the HEQ5. I made sure the polar scope reticule was aligned first but I didn't bother to set up the date scales. Instead, like a lot of people, I used the Polar Finder software to find out the position of Polaris on the reticule circle. This worked each time. It could be that your date scales have moved. Download Polar Finder software - it's free - and I bet you'll find the scales have moved. I assume you've got everything else correct - date format, mount levelled, axis lock screws tight, power to scope OK (no blinking red power light), etc? Good luck. MD
