  1. Fantastic image Barry! And the background galaxies are a thing of beauty. It got me looking at my own work-in-progress version to see if I could see the cap as I had never heard of it before - it is just about there with 8.5 hours of Ha but I'm never going to be able to capture it as well as you have here with UK skies. Ditto with that faint white arc just to the left of the galaxy - is that IFN? It looks more like some sort of shock wave.
  2. Are you keeping an image history, ie. HFR / star count statistics? When I was using an ASI1600 I seem to remember that was taking longer than the actual download on my very low spec (but USB3) laptop until I disabled it. You can tell how long it takes by seeing how long the "Analyzing Star Data" message is displayed at the bottom.
  3. I have a dehumidifier running in my obsy. I put a power meter on it a while back, and I seem to remember I worked out that it was costing me about 30p per day on the damp days (often in NW England). So not cheap as Olly says, although not the end of the world. It keeps the shed at 55% RH.
  4. I tried using wifi extenders to reach my obsy via Teamviewer (probably about 20 metres) for a few years and they were flaky at best. I changed to use powerline adaptor/extender about 6 months ago and the improvement is massive, both in terms of reliability and bandwidth. By the way, my obsy is on a different circuit to the house, it still works fine.
  5. Another in agreement here. I imaged with a C9.25 (slightly heavier admittedly) on an HEQ5 for a year or so. It often worked ok but there were odd periods of frustration with dropped sub after dropped sub. It was all so much less stressful when I upgraded to an NEQ6.
  6. Typical really - I spent late Jan and most of Feb imaging this galaxy, stopped a week too early. Having read this heads-up I had to just make 100% sure by checking my last sub - even though it was taken on 21-Feb!!
  7. Nice pic. Glad there's someone else on here now who's got a Toscano RC! I've had a 10" truss one for a couple of years now - don't think I've ever got it 100% fettled but I'm not far off.
  8. Very nice. I took a couple of subs of this myself recently, but gave up when I saw the effect of that bright star - great bit of processing to get it looking so clean.
  9. I've seen this a few times, it was due to having too low a threshold on the star selection, ie. too many stars used for alignment. I usually adjust the slider and aim for approx 50 stars.
  10. Thanks John. Great images, I've always liked long FL setups as I feel they give you a greater variety of targets. Imaging at F4.5 sounds a lot more enjoyable than my slow RC.
  11. Wow that's impressive, I've never seen an EQ6 look so small! Do you have any issues with tube-flex imaging with such a big newt? Must admit, I've always fancied putting something like that on my EQ8, but a worry that it would be a world of pain.
  12. Does anyone happen to know the polarity of the 2-pin EQ8 power connectors? The supplied plug itself has the two pins numbered 1 & 2, and from looking at the supplied documentation it appears the pin numbered 2 is the +ve - I also confirmed this was connected to the centre pin on the cigar lighter plug. However, having now cut the cigar plug off, when I try it with a multimeter pin 1 is connected to the white-dashed wire - I thought by convention white dashes indicated +ve, so this is opposite to what I expected? Fairly sure pin 2 is +ve, but trying to avoid a blown circuit board, so any help would be appreciated.
  13. I had the same issue the other night downloading them. Thankfully I found copies on an old PC, don't know if they'll be too big to Dropbox?
  14. If you are doing mono LRGB processing you can't put all your LRGB in a single stack and expect DSS to combine them. You have to stack the 4 channels independently, then use your imaging processing software of choice to do the combination. The only way it can help with the combination is that you can use a single frame from one of the channels and select it as the reference frame, which will at least mean the 4 channels will be aligned when you come to combine them in Photoshop for example.
