  1. Thanks Peter - I finally resolved the issues I was having with black artefacts caused by cold pixels from the dark frames and so was able to do a full calibrated process. Here is the result, which I think is an improvement on the light frames only version; certainly better colour depth. So this one is 11 x 360s lights, darks, flats and dark flats processed in PI using WBPP. Interestingly the recommendation from Adam Block was to put the dark flats in the Bias tab and let PI sort from there (rather than in the darks or flats tab) and this worked extreemly well. Modest tweaking in post
  2. Thanks Bryan. Could do with more exposure but the cloud gods thought otherwise. Just grateful for what they allowed me. Keith
  3. This has been years in the making for all the wrong reasons - wrong telescope/wrong camera/wrong weather - I've had the lot, so I've never managed to get a single image of the Andromeda Galaxy, until now! This is only 66 minutes and is also only lights - no darks, no flats & no dark flats - taken with my AA ED102 Triplet, A .79 reducer, AA 269c CMOS camera and processed in Pixinsight. Minimal clumsy interference from me, so I'm quite happy with it.
  4. This is first light through my new set up. Altair Astro 102 Triplet using an Altair Astro 269c with an Altair Astro Quad filter. Guided with QHY 5-11m and a QHY mini guidescope using PHD2 This is a total of 5 hours 20 minutes exposure in 360 and 600 second subs - 560 Gain and Offset 24, captured with APT and calibrated then post processed in Pixinsight. It has to be one of the best data sets I've ever had the pleasure of processing, taking little effort due to the low noise. It was captured on 19th & 20th December under partial moonlight. I now have the Altair .79
  5. I seem to be the only one to have this problem (?) With the new version 1.8.8-7, I get a processed image that shows Hydrogen emission nebula in IC405 as green with the image flipped. When I revert to V 1.8.8-6 and process exactly the same data with exactly the same settings, it comes out as red and orientated as I would expect from previous images. I am driving myself nuts with this as I cannot use the new version (or move forward with PI) in this state. The images are captured with an Altair 269c using APT and processed using set parameters in PI that I have used for some time. I ha
  6. Interested to know what happened here. I have an old SXV M8c that I have had for years. I have recently been using it in an old William Optics ZS66 with some excellent results.
  7. Thanks for the info guys - it’s almost pristine and looks hardly used. I reckon the gears should be ok having owned a CPC800 for a number of years, unless wedged, they don’t suffer too much. Knowing the lady, I very much doubt she ever wedged it. I’ll go for 375 with the extras and see what happens. Easier to go down than up keith
  8. Afternoon all I'm going to sell for a friend a Meade 90ETX with electric focus, 3 x EPs, variable polariser, Barlow etc, Autostar handset and the eq/altaz mount and tripod. Optics are in great shape - it's from circa 2004 and complete with a case for the set up. I need to just test it to make sure it fires up, but pretty sure it will be fine. Any pointers as to potential ballpark value please. I want to try to max the price for her as C-19 has hit her hard financially and she needs every penny she can get. From some research, an asking price of about £400 ono - how would that so
  9. Thanks for the advice. I also posted on the SharpCap forum. Robin replied that it's a case of the previous settings from the camera being retained and needing clearing with the new version. Opening the camera while holding down CTRL totally worked and the QHY5 is working fine again now. Jeez....!
  10. This is a weird one! I have two QHY5-111 178 cameras - one mono and one colour. I use Sharpcap Pro V3.2.6433 and W10 The mono camera is recognised, frame rate around 50fps and the black screen goes bright white when I remove the sensor cap. The colour camera is recognised, frame rate around 25fps (because it's colour) but the screen remains black when the cap is removed from the sensor. The camera was sent back to QHY and they 'repaired' it but I have no idea what they did. When it came back, it was the same. Modern Astronomy have sent me a brand new one to test - same thing happens!
  11. It's funny how some glorious images just don't get the recognition they deserve on many forums. This is not only an excellent capture, but it's very sympathetically processed too. Not overly aggressive or forced. It shows the value of good data in the first place, that requires sensitive processing rather than 'pushing'. What software did you run it through?
  12. That is gorgeous! You are not just a planetary imager any more. One of the best amateur versions I've seen.
  13. Well I'm happy. I went ahead and bought one, installed everything, mounted the PC to my setup and tested it. Everything works well and using W10 Remote Desktop I can look forward to the autumn & winter without freezing myself half to bits. Thanks for the assistance and advice, much appreciated.
  14. So, to conclude - this looks like a good one for the price. It will presumably run all the necessary software (Maxim, APT, Sharpcap, PHD2 & CdC) with me just linking to it from the laptop, thereby avoiding WiFi drop trashing my set up & guiding. Am I right with that? Only ever used usb hardwire till now Radec
