    Been trying to get a starry background along with a 'fixed' comet image and really failed before - this ones not too bad but there are still a few artefacts around to be sorted:

    There's always something new to look at with Jupiter. Recently I have seen the GRS make it way across the disc several times, at least one shadow transit and constant changes in the formations of the moons. Tonight was something I have not seen before as far as I can recall. The moons were all aligned to one side of the disc and seeing was pretty good (once it had cleared a neighbour's chimney pot!) with the moons showing as discs of various sizes. The disc itself was showing really nice detail with the GRS very obvious and showing a rim of dark red. The main bands and polar regions were revealing nice levels of detail. At just before 8.45pm Io was getting very close to the disc and as predicted by the S&T utility began to fade as it passed into Jupiter's shadow. This happened well before it 'hit' the disc and the moon became quite orange in colour and then grey as it finally faded to nothing. Pretty impressive!

    Hi Karl: I see that you want to continue with the remote setup. Several setups that I have seen on NightskiesNetwork use the QHY5ii guide camera and the 50mm guide scope. Given that the guide camera has only the 1/3" chip, the image scale is more than enough to centre up objects when used as a finder. It actually shows some objects better than the main scope d/t the larger field. If you get a chance, catch "HeavensDeclareGodsGlory" 's broadcast by Don. He uses this exact setup to good effect. It doesn't have to be the QHY camera either as other guide cameras work too. Don can see the finder image in PhD and centre it up. Easier on the mount too as payload is less and you probably already have a finder.....Dwight

    Best you can get for under £50 . Fantastic eyepieces. They only go up to 25 mm f/l , BUT about. 60 degrees fov compared to a 50 degree fov that the average plossl provides. You also get good eye relief compared to plossls. I've not read one negative report on bst starguiders .

    Hi, This is a good capture. You are in focus and have round stars. You have also achieved a flat field. I think the data could give more at the post processing stage. Two things jump out at me first of all. 1) The colour balance is off, with too much green and not enough blue. As you stretch the linear data I'd suggest you cut back the black point (Levels, move the left hand slider to the right) so as to get the top left of the histogram peak aligned in each channel comme ca; Be careful never to clip too much off. A final cutting back is the very last thing I do in processing. See below; If the blue channel still looks a bit thin you can give it a slight lift in Levels (mid point slider to the left) or Curves. 2) I can see the noise reduction instantly. It gives a 'vaseline on the lens look,' to quote Steve Loughran. I do sometimes use noise reduction, but very selectively and only on the darker parts of the image. The bright parts don't need it and do carry the detail which NR destroys. Two good reasons for not applying it to the bright stuff. There are various ways to select the regions for NR. You can use the Colour Select tool experimentally (the fuzziness slider decides how wide a range you select with one click) and apply NR to the selection. You can do it this way but to a layer underneath and then use the eraser on the original top layer to let the NR through. You can make a mask between layers based on brighness. I just use colour select. I use masks far less than most people but I'm not making a virtue of it, it's just what I do. Note that this reply is in response to a PM from the OP. I'm not trying to rip his image to pieces!! Olly

    About 110 x 15-second subs, shot through a layer of thin hazy high clouds - don't seem to have cost me too much detail, though my stars are a little bloated. Cropped out a reflection artifact at the bottom. Suggestions for improvement always welcome. :-)
