  1. Nice job. I like both, but the starless version seems appealing to me since there are not many starless renditions of galaxies.
  2. Someone will correct me if I´m wrong but I think you can adjust colors in post-processing. I´ve never bothered in doing so in my 600D but for daytime photography: just take a picture of whatever you want and then auto adjust white balance using that picure. IIRC, this setting remains until you remove the battery.
  3. Precisely, you have to connect the camera directly to the telescope (primary focus). You´ll need an adaptor from NIKON to T2 and another one from T2 to 2 inches. Then just focus and shoot!

    Hello!

    Hi and welcome to SGL.
  6. Good job @carastro I also prefer the first one. Not an excesive amount of stars. Thinking about buying a refractor some day, I keep looking forward to see more from that ED72. Did you use FF/FR? Did you find any trouble in managing stars colours during processing?
  7. Excelente imagen. Congratulations!
  8. In terms of arcsecs/px resolution yes (aorund 2 is a good value), but with lower DR and FW than with bin1.
  9. The original resolution of this camera was 11Mpx - 4144x2822 pixels (bin2). ZWO later “unlocked” the bin1 mode: 44Mpx - 8288x5644 pixels. It might be appealing, but you have to bear in mind that in bin1, the pixel size is 2,31x2,31 microns so the light gathering capability decreases dramatically. Just look at the charts in the manual and you’ll realize that the bin1 mode is much less effective. However, you always have it there in case you might need want to use it (perhaps with scopes FL<300mm). As stated by @vlaiv, good luminance data is paramount. Add as much integration time as you can (you’ll never know what night is going to be better) and finally add some RGB to color the luminance layer. I personally take between 0,5-1,0 hours per color channel. I use gain 120, offset 30 and -20ºC. YMMV though. I haven’t experienced any issues with my flats. Following some advice I read somewhere, I use exposure times over 1s: from 2s for luminance to 30s for SII.
  10. Astrometry.net is the tool you need. It solves the image and provides orientation, visible objects... Here is the result: The trails seem to follow the DEC axis so it is likely a bad PA.

  12. It seems to me that the Star Adventurer is not tracking properly. Take a close look at the stars and you will see an elongation in the same direction of the M31 drifting.

    Hello all

    Hi and welcome to SGL
  14. I think it was in the SSD but I'm not sure. But even doing so, just reading 300+ files from any external device is going to slow down the process a lot.
  15. I've tried to process images in PI from an external HDD USB3 and the proccess was really slow. I've realized that's better to copy them to the iMac SSD and delete them once the processing's finished. Never tried from my NAS since I believe it'll be worse.
