    Both great images, can't really say about the Nii making any difference.
  2. MarkAR
    Excellent.
  3. MarkAR
    Wow, that a great image. Unusual little target, thanks for putting in the effort on it.

    Watched a video by Amy Astro the other day and she had loads of guiding issues because of play in helical focusers. Resolved the issue by getting rid of it. https://www.altairastro.com/precision-camera-focuser-for-auto-guiding-with-altair-60mm--80mm-raci-finder-scope-86-p.asp

    Amazing images, superb proms and one hell of a massive disturbance going on.

    I would opt for the 17mm. Prime lenses are generally better than zooms and F2.8 is plenty fast.
  7. MarkAR
    Big improvement, well done.

    Stunning mosaic, gorgeous area of the sky with so much going on. If you used Pixinsight then loading the image I think includes the process history. You can then copy all the processes to a basket or drag to the window and apply to the new images keeping all the same settings.

    There's the possibility that if it's adjusted too tight there might be binding issues with the gear. Just a long shot I know.

    Not sure if USB3 is that crucial, if it is then just run that to the miniPC. Everything else can go to the mount ports then to the PC.

    If you move the Alt-Az bolts you will lose polar alignment. Your best bet would be to use software like KStars/Ekos which has a really good PA routine. Then plate solve using the alignment module. If your mount has a USB port (same as a printer) then you can connect directly without the handset or if not then either through the handset in PCDirect mode or via an EQDIR cable.
  12. MarkAR
    Why not just hook everything up to the mount ports as normal and then to the mini PC which you can mount to the base.

    Another alternative is an M42 lens. Theres a few on Ebay 400mm and 500mm.

    These are stupendously good, really sharp and crisp. I think they must be your best so far.

    Nice set of proms showing, the one at 4 o'clock looks pretty big.
  16. MarkAR
    I think it's NGC-7822, an HII region.

    Excellent image Adam, well done. Zoomed right in on the cropped image and it looks really nice.
  18. MarkAR
    Very good start on this, more exposures might help and increasing the saturation a little should bring up colour. Also be careful of making the background too dark, clipping can lose you some detail in the fainter galaxy arms.
  19. MarkAR
    Very good for a fairly short total exposure time, more data will definitely be a benefit.

    Superb prom, looks great to me.
  21. MarkAR
    Excellent image, well done.
  22. MarkAR
    Lovely capture. Such interesting malformations in the spirals.

    NGC 7000

    Lovely image, well done.

    Great first effort. PI is a superb piece of software.

    Looks pretty good to me. Maybe try experimenting with longer exposures see if it brings out more nebulosity.
