  1. Hi. Yes, it works fine here. Which solve is failing? PS2 or asps? Do you have the latest ansvr? Have you downloaded the fits libraries for your focal length? Is the fl entered under the tools tab? Tell us the sequence of events you use....
  2. FHi. I'm not planetary but I seem to get the idea you use a a powerful Barlow, take a video of the planet and then use software to stack only the sharp frames (?). HTH.
  3. Hi. Do you know what type of artificial lighting is responsible? Modern lighting cannot be filtered. The old type of Na or Hg, can. Maybe check before you buy? HTH.
  4. +1. So sad to see a pristine telescope indoors with so much ambient light!
  5. The bearings were discussed here. If you take it to bits, make sure you have some sheet teflon to cut new washers. Milk containers are a good source. HTH.
  6. Hi. Yeah, that's it. Anything -there aren't many I don't think- where something overexposes if you stretch for the dim stuff. The core stars in the Orion nebula are famous for only being visble in a HDR layer. HTH.
  7. Unless it's something with very bright highlights, I don't think so. If you want to have a go at high dynamic range, you can take the same stack and layer different stretches. HTH
  8. Another planetary but bigger? It rises a little later than the ring: m27. HTH.
  9. Hi. Nice shots. JTOL; I wonder for the earthshine it would be possible to scale both shots and then layer them? It may make an interesting shot.
  10. I had something almost matching this description when dew formed from polluted air which I traced to smoke from a bbq; the water then evaporates leaving the solids from the smoke particles forming a film. I'd guess the ravines are where the condensation has coalesced into droplets and run under gravity. I removed it with one of the cloths used to clean spectacles. HTH.
  11. I've run out of excuses. Maybe we should have a tick list for each post: cloud, rain, cold, hot, hazy, owl, time, tracking, filter... So how about it was hot, dark, late, sticky and noisy. Not had those for a long time. But seriously, any comments here most gratefully received. TIA and for looking. 24x150s.
  12. With turbulence over the southern horizon rife, the 700d sensor at 38º and the smoke from the San Juan fires, it was StarTools' superb deconvolution to the rescue. There's noise but it's bearable, as isn't the chromatic aberration from the cheepo cc making it look like it's been taken with an expensive refractor;) Thanks for looking and cool clear nights.
  13. Hi. My findings and explanation from the engineer of my 700d. A Wratten 8 will cut most of the violet and uv recording as visible on the sensor. At the other end of the spectrum, the uv-ir filter will block the long wavelength ir recording on the sensor which the hot mirror modification used to handle. They're only cheap items so, no harm done in seeing which combination works best for you. HTH.
  14. Thanks Neil for the hands on. My contribution: Dim object, dslr, 26º ambient, 36º sensor with my -new to me- Bresser nt150. I like the idea that galaxies are a decent size rather than a fuzzy patch. Would cooling it reduce the noise? I'm beginning to accept that maybe heat makes more noise. How would I cool it? Or would I buy a cooled osc instead? TIA.
