  1. Thanks guys - it's one of those things I've wanted to get for ages but knew if I set out to do it, I would always mess it - had to rely on a bit of luck
  2. I will run it through PIPP and tidy it up a little - just super excited to share!
  3. First light playing around with a Lunt solar wedge and a Sky-Watcher 72ED with SolarQuest mount and ZWO ASI178MC... pure luck but I am super happy!

    Imaging Challenge #15 - The Milky Way

    Please enter entries for this imaging challenge here.
  5. I think they are very good and excellent value for money compared to other options out there. You can visibly see the difference it makes, particularly if you look around the edges. I'm sure there is a better way of setting them up but I find a bit of trial and error usually finds the point at which the colour fringing / smearing reduces. I'll have to try the FireCapture RGB alignment tool - that sounds useful!
  6. I've just applied a bug fix to resolve this issue
  7. It's worth mentioning AutoStakkert! has an RGB align function which can help during stacking: http://www.astrokraai.nl/software/latest.php
  8. Atmospheric dispersion corrector = ADC - I've been using the ZWO one: https://www.firstlightoptics.com/zwo-accessories/zwo-125-atmospheric-dispersion-corrector-adc.html It does a really good job of re-aligning the colour channels back together again, correcting for atmospheric dispersion. The ZWO one is really good value for money, they used to be a lot more expensive.
  9. Blue is always the worst channel as it gets scattered the most. Using an ADC will help bring the colours back together especially with Jupiter being reasonably low at the moment but you will need exceptionally good seeing with Jupiter as high as possible to get the blue channel tighter. You can try splitting your stacked image into each channel and then applying wavelet processing individually to each one before recombining - the splitting and combining of channels can be done for free using GIMP. This might allow you to improve the blue. I'm not 100% sure, but you might be able to use something like PIPP to separate the channels prior to stacking and then apply different aggressiveness to the quality cut-offs to improve the stacking of each channel.
  10. Excellent write-up Kirk - very useful information
  11. Anything you like - as long as it fits the Milky Way theme - I don't see a problem if you only capture a portion of it
  12. There’s an ISS lunar transit here tonight - any recommendations for settings with a ZWO 178MM camera? Any tips / tricks?
  13. Found it - we don't send newsletters so I've removed that widget (which only appeared if you hadn't already opted in to newsletters).
  14. I’m not sure what you mean Jeremy? Can you take a screenshot - I don’t see any newsletter button?
