  1. Leo has nearly passed me by! I really haven't been keeping up recently...

  2. I have got Deep Sky Stacker running well in WINE, but after that I'm not sure what software to use to process my images. All I really need is to remove gradients (there is a method for doing this in GIMP... though it usually only partially succeeds.). There must be at least one or two other Linux users on the forum besides me, right? Interested to hear other people's workflows.
  3. Saw 2001: A Space Odyssey for the first time today, that was a good film :happy10:. And left my friend's house to see the moon above my head :happy9: little spooky after having just finished the film.

      My all time favourite film ever. A classic that holds up very well considering it was released in 1969 just before the first moon landing. :) 

  4. Indeed, I will certainly be returning to Auriga soon I may get a filter or two as well, since I haven't had one since selling my 130p... Maybe an h-beta and an OIII... DST and summer non-nights made sure there wasn't too much to post about... And then the nights got longer and the clouds rolled in. The night I made this report was the only clear day in a month of cloud I wouldn't blame my sky personally... My ability to get lost is limitless "Uranus is RIGHT THERE in the screenshot!"
  5. I got the chance to go out observing last night (first time in a little while). Looked at some usual targets: M43, Flame, Pleiades. Managed to see M78 for the first time. I had a wonder around Auriga last night, since I'd noticed a grey fuzz in the middle of it naked-eye and wanted to see it a bit closer. It became a bright open cluster through the finder, about where the flaming star would be (if my skies weren't quite so hazy and bright). I also noticed some new grey fuzzy patches nearby in the constellation, looking at them through the 24mm EP I found them to be some very nice looking clusters. Dense, bright and patterned. I'd seen some listed in Stellarium but didn't know they were this easy to find/see. A nice discovery. Also, naturally the eskimo evades me yet again... ~pip A photo from the night:
  6. Finally got to see M78!

    A bit fainter than I thought, but still impressive. I'm not surprised I missed it the other times I went looking.

      Congrats Pip! Have you tried the Merope nebula?

      I did look at the Pleiades that night, the cluster is very bright but I have never seen any nebulosity. Unless I have, but didn't see it due to the brightness of the stars.

      Merope looks like a "paper fan" and will also have a curved inner section to it under VG conditions and no filter is used of course. It will look bigger than you might think, keep trying this one Pip, there are nice rewards in the Pleiades.

  7. Using GPU compute libraries isn't simple. Unless you're already a very experienced programmer I wouldn't suggest diving into CUDA or OpenCl. They require... more than a bit of setup. For image processing, GPU acceleration has the potential for a HUGE performance increase over CPU, but I don't think any existing software really makes use of it unless it's for scientific purposes or for 3D rendering (3DS max/Blender etc) (some video encoders and I think Adobe after affects is all i can think of atm.) For a glimpse into GPU programming, have a look at this: http://simpleopencl.blogspot.co.uk/2013/06/tutorial-simple-start-with-opencl-and-c.html
  8. I have a Nikon D3200 & a 250p dob. I was wondering if it's worth buying adaptors so that I can attach my DSLR to my scope in order to image planets, the moon etc. I would guess I need the nikon version of these, do i need any other adaptors? Also, if I just attach the camera to my scope, won't it just be like using a 1200MM f4.7 lens? Will I need a barlow for it as well? Especially since just having the camera attached to it will leave the sensor exposed otherwise. Will the earth's rotation make things difficult? Thanks ~pip
  9. Oh, drops INTO the 80's? Now that IS hot. Perhaps removing the back and making sure there isn't a tonne of dirt further inside would be a good idea. (Maybe get a local shop to do it for you if you aren't confident) Don't bother with the cooling tray, it'll cool the bottom plate of the laptop slightly but in terms of chip temps you'll see a difference of a fraction of a degree.
  10. Chips can run hot. I mean. Boiling water hot, before any real damage can be done. If your computer gets too hot, it'll shut itself off before it hurts itself. Intel chips are typically rates at around 95 degrees. If possible, take the back off the laptop and see if there's dirt/hair/cat fluff stuck in it. But I don't think that's necessary.
  11. By binos are back in action! Though I've realised they need some... cleaning.

  12. And it's the view that keeps you interested every time you see it. I don't think I'll tire of the sight of Orion rising from the east.
  13. PixInsight seems to be a favourite around here for stacking, and with all the features it has, I am not surprised. For mosaics, try Microsoft Image Composite Editor (free, but very good) For image processing (post stack/mosaic) I'd say the best bet is still currently photoshop. GIMP (GNU Image Manipulation Program, naughty!) would be a suitable free replacement once the 2.9 release becomes official and not "beta", but even then there are quite a few plugins for PS that are helpful for astro (aka. "hasta la vista, green", although I think you can do exactly what that program does by using LAB color and putting the brush to "lighten") I'm not sure about mount control, but I think stellarium has some features for that. Someone will be around sooner or later to point out all the software I've forgotten to mention Happy hunting! ~pip
  14. I duplicated the image's layer, in the duplicate I ran a despeckle filter and then removed remaining stars and the nebula as best as possible with the clone tool. I then reduced the brightness of the duplicate layer by a tiny bit and set the layer blend mode to "subtract". I then merged the layers together and stretched the resulting single layer using curves. I did this all in GIMP. I think the normal versions of GIMP don't support high bit depth images but this one was from the 2.9 dev build a while back with that support built in.
  15. Just had a go at that file, it's got some good data in it: Although I think it's worth mentioning that the image has suffered a fair bit because of the reduced bit-depth. (A 16-bit file wouldn't have produced the banding seen in this processed version.)
