    Default Hugin

    I've done some rudimentary stacking at least with Hugin on Linux. It worked, but I probably wasn't using the full potential since I couldn't use the .exr files it outputted by default.

    what did you stack? Did Hugin do the job ok?
    If it doesn't export as a different image file type, would it be possible (though crude) to use the PrntScrn button to paste the image in to another software package and then trim it accordingly?

    I started off using ORSA under windows but found it to be very unstable and even had trouble saving and loading files, so I switched to the Linux version and (nearly) all my problems were solved. I've been having trouble with the "observer locations" function though; no observer locations show up and there does not appear to be any way to add them, even after downloading the observatory codes file from the minor planet center as listed in the update function of the program.

    Other than that it's a great program; I used to use Universe Sandbox, but ORSA is a much more professional tool with far more functionality and since it's open source, it's free.

    Sorry about the late reply, I hope you'lll still notice this.

    I was stacking images of the area around Polaris. I shot that simply because it's the only part of the sky which tolerates long exposures.

    I think I didn't get Hugin to do stacking for me as such...basically it would output .exr files which were probably stacked, but nothing could read them.

    But it *did* align exposures as long as they weren't too different. So I ended up aligning 30 exposures, and then stacking them crudely in GIMP. In the end I probably at best kept the dynamic range and seeing the same: what I *did* gain was an image with significantly lower noise:

    Default Star Charts for Linux.

    Star Charts a.k.a Cartes du Ciel, is a program which enables you to draw sky charts, making use of the data in 16 catalogs of stars and nebulae. In addition the position of planets, asteroids and comets are shown. I use this program on a laptop at the telescope while observing. It also has telescope control support. The purpose of this program is to prepare different sky maps for a particular observation. A large number of parameters help you to choose specifically or automatically which catalogs to use, the colour and the dimension of stars and nebulae, the representation of planets, the display of labels and coordinate grids, the superposition of pictures, the condition of visibility and more. All these features make this celestial atlas more complete than a conventional planetarium. Since I'm new here I can't post a link but do a Google search for "Star Charts" and it should take you to the home page for download.
    Also, if you need a shell script to turn your screen red while observing, search for "xcalib". This is a monitor color calibration script that allows you to change the display to red and back to normal using a simple shell script.

    Default Re: Linux Astronomy Software

    Hello there,
    I'm considering buying a new laptop/netbook for the purpose of running Linux. My question is does anyone use or has anyone gotten SkyTools 3Pro to run under Linux, using WINE or otherwise? If so, were there any issues?

    Hello.

    I'm a new telescope (Nexstar 6SE) user and an old Linux user. I'm using ArchLinux and Mint. I'd like to know, if I buy a CCD camera, what to expect if I am a Linux user. Is it just detected by the kernel and I can use any web cam app to "record" what I am viewing? Thanks in advance.

    my guess would be:
    ArchLinux: depends how you set it up, as it's pretty customised/minimal.
    Mint: I'd expect Mint to record a webcam without any fuss or need to set up, my webcam (on Debian) just worked out of the box (cheapest philips webcam) but don't know about CCD camera.
    I'd be interested to know how you get on with CCD - or if anyone else has such experience.
