      I have a CPC 800 Edge HD as well as an Orion Starshoot Autoguider.  I recently ordered a ZWO ASI294 MC Pro colour camera.  In terms of the auto guide function I had planned on using PHD2 (which I already downloaded onto my Mac laptop).   In terms of researching software that would allow for control of the camera I understand there are a number of options. I considered purchasing an ASIair, however, I understand that is not compatible with the Orion Starshoot Autoguider, and therefore I would need to replace that with a ZWO.  I am hesitant to want to do that, even though it would be convenient not to have to bother with laptop connectivity.  Right now I've been using my iPhone for goto functionality with Starsense and Skyportal wifi.  I understand there are a number of options available for Windows based PCs in terms of control of camera and image acquisition.  BackyardEOS (for DSLR cameras), Astrophotography Tool, and Nebulosity.  These seem to be the most popular.  However, it looks to me as though APT is just for Windows based PC.  As well, not sure the extent to which Nebulosity is seamless when it comes to Mac compatibility.  Is there a recommended Image Acquisition software for Mac users?  Is a Windows PC laptop dedicated for astrophotography the best approach (e.g. second hand etc)?  I would appreciate your recommendations.  Thanks

      Hello everyone,
      I developed an Android app - Telescope.Touch - capable of connecting and controlling INDI/INDIGO devices, for those of you who use Raspberry/Astroberry/StellarMate.
      It's really powerful, and a lot of new features are in the works.
      Mobile planetarium derived from the Sky Map project Mount and focuser controller with directional pads and speed controls Receive images from INDI CCDs Database full of objects to which you can point the telescope directly from the app INDI control panel compatible with every device Aladin Sky Atlas preview and altitude graphs Astronomy utilities: polaris hour angle, compass, red flashlight Languages: English, Italian and French. Sky maps are translated in almost every language. It is available on Google Play: https://play.google.com/store/apps/details?id=io.github.marcocipriani01.telescopetouch
      A Pro version is also available, mainly to support the app's development: https://play.google.com/store/apps/details?id=io.github.marcocipriani01.telescopetouchpro
      I hope you enjoy it! I'm open to feedback and improvements!

      After many hours of fiddling round with Registax wavelet settings to process my own solar system images, I've always been curious as to how it actually works. In doing so I've put together my own image sharpening program which does something similar to Registax wavelets. For comparison, I've also added some general purpose deconvolution techniques which you'll probably be familiar with from other image processing software (like Wiener inverse filtering, Richardson-Lucy, etc). In choosing a point spread function to deconvolve with, one suprising result was that the typical stack outputs from Autostakkert work best with a Lorentz point spread function (with a minor modification). Deconvolving with a Gaussian point spread function doesn't really work. Deep-sky images seem to deconvolve best with a Moffat point spread function (which is to be expected - it's already well established that star profiles in long exposures are best approximated with a Moffat function).
      On the whole, it's unlikely that you can sharpen solar system images much more in this program than you already can in Registax. You can see results from Registax wavelet (sharpening layers), inverse filtering (e.g. Wiener), and iterative deconvolution (e.g. Landweber) below. They all give very similar results. In all the techniques there's a similar trade-off between less noise but less detail vs more noise but more detail.
      There are some quick start notes on the first page of the Readme here:
      There are some examples of deconvolved images here (move mouse over image to see before/after):
      Image credits are on the hyperlinks
      The Windows download is here:
      Example solar system tifs to experiment with are here:
      And the project page is here (with Source code in the src folder)
      If anyone finds it useful, do post here how it compares to other tools you use for solar system image sharpening.
      The download and the source code are free, you can use it unrestricted for any purpose. The OpenCV and OpenCVCSharp components which my program use have licence information at the end of the Readme.pdf.

      Hello everyone,
      I've read about Starnet++ lately and I wanna give it a try. Tried to get it from here but there are some issues. It seems like I can't find any viable kit.

      I would really appreciate if someone can provide a link to download.

      Thank you,
