  1. AZ GTi with Raspberry Pi4 running Astroberry I thought it might be useful to post this how-to given that I've spent the last week banging my head against a brick wall trying to get my RP4 to connect to my New AZ GTi scope. The idea was to develop a small, portable goto setup that could platesolve and guide. I’ve yet to image with the setup but here’s my quick guide to wirelessly connecting the AZ GTI and win 10 laptop to the Astroberry hotspot to run a complete wireless imaging system. Ø Set up the AZ GTI with equatorial mode firmware o Go to http://www.skywatcher.com/downloa
  2. Thanks, will give the balance a shot and check cables etc
  3. I'm not 100% sure whether its in RA or Dec to be honest. I use Stellarium and Stellariumscope to slew and star align then guide with PHD2 and use APT to image. In PHD 2 the image drifts to the right rapidly straight after slew. A few reverse pulses on the gamepad stop the drift. Balancing issue maybe?
  4. Thanks, the problem is it drifts rapidly and completely off target...
  5. Hopefully someone can help. When I slew my NEQ6 it keeps drifting until i apply a couple of reverse pulses on the controller. I'm using it via an eqdir cable to my computer. Any ideas? Could this be a backlash issue?
  6. It was about 2 hours of 5 min exposures with darks and bias frames stacked in Siril. I used an Altair triband filter on the QHY183c.
  7. First light. Loving this lens already! QHY183c. with Altair Triband filter.
  8. Looking for some advice. I'm currently imaging with a QHY183c and Equinox 66. Would an Evostar Ed72 provide any noticeable improvement? The Equinox 66 is FPL51 glass I think but I can't find any info on the ED72. Thanks
  9. So, got to the bottom of the problem but unfortunately no solution. I was using a newer version of APT on my main computer. I updated on the obsy pc and its cropping the pics slightly. All settings exactly the same. I'm none the wiser why its doing this but apart from having to reshoot all of my calibration files its not a huge issue. Does make multi session stacking problematic though as I can't use any of the old data.
  10. Probably bortle 5. Sounds like the conditions weren't the best... Just need some clear skies to retry!
  11. Unfortunately due to limited imaging time. I took the darks the following day.
  12. Thats what I thought. Cooler was definitely running. Fits header says Image #1 SIMPLE = T / file does conform to FITS standard BITPIX = 16 / number of bits per data pixel NAXIS = 2 / number of data axes NAXIS1 = 4656 / length of data axis 1 NAXIS2 = 3522 / length of data axis 2 EXTEND = T / FITS dataset may contain extensions COMMENT FITS (Flexible Image Transport System) format is defined in 'Astronomy COMMENT and Ast
  13. Both these photos were taken at -20 on a QHY163c and QHY183c respectively. Stacked with darks. Is the level of noise normal? Details - QHY183c @ -20 degrees, 20 lights at 300s each, 44 darks 300s each, stacked Details - QHY163c @ -20 degrees, 10 lights at 300s each, 20 darks 300s each, stacked in Siril
  14. Looking for some help. I've recently got a QHY183c and managed to get an imaging run in yesterday. I then took 2 hours of darks today on a different computer but can't stack the darks with the lights as they are slightly different sized images. Any ideas? Lights are 5544 x 3692 and darks are 5544 x 3684....
