    That's lovely!
  2. Solar Imaging Without Tracking?

    Oh I know it won't hurt. But I can't see how "turning the red channel up"* would ever deliver more detail than a mono camera with the same sensor in the same conditions. *I presume that you mean increasing the gain?
  3. Solar Imaging Without Tracking?

    I cannot see how that is possible @xtreemchaos, as the light coming into the camera is the same frequency. Yes, if using a telescope to image the moon you can use a red filter to cut out the blue frequencies (these are most disturbed by the seeing) to help "cut through" the seeing, but on a hydrogen-alpha scope the scope itself strips out all of these frequencies before the light hits the camera. It's, AFAIK, impossible for a colour sensor to get more detail than a mono sensor* as the green and blue pixels will be doing nothing other than adding read noise into the final image. Even if you separated the channels and only used the R channel then the mono would still win hands down as it is collecting data across all pixels, whereas the colour sensor is only collecting data in one of four pixels. *Naturally assuming that the sensor are the same type, just one is mono the other colour. If your mono camera is using a completely different sensor to your colour then all bets are off.
  4. What makes you think that there's a problem with the optics? Have you tried a star test?
  5. Strange "double stars" with OAG

    Is the pick-off prism silvered or clear? it might be an internal reflection in the prism. Perhaps blackening the rear of the prism would help?
  6. Whats wrong with my stars?

    My tuppence worth* The stars in the top left, top right and lower left are elongated as if they are rotating. That could be coma and the spacings might need a slight tweak. There is some aberration in the brighter stars diffraction patterns, but it's fairly minimal. Like you said, it's probably the focuser tube. Personally, I think that you're getting into the realms of "pixel-peeping". A tweak of RC-Astro's "Star Shrink" (or the equivalent Annies Actions/Carbonis Actions) would probably solve most of it. Or even a mild cropping of the image. *I am far from being an expert, so take this with a large helping of salt
  7. Solar Imaging Without Tracking?

    Have a look through this thread. it has answers and more to similar questions:
  8. Half- Moon shaped guide stars with OAG

    They all do that Sir. Luckily, PHD doesn't seem to care one jot and it can still calculate the star centroid.
  9. The Cave Nebula, Sh2-155

    Wonderful. Just wonderful. Lovely subtle processing without the garish saturation and colours that many seem to employ now (Pixinsight, I'm looking at you).
  10. WiFi - need more signal.

    If they are providing fibre to the premises then they will need a fibre capable router. however you should be able to hang any Wireless Access point of it to improve the WiFi coverage.
  11. WiFi - need more signal.

    I should be on commission....
  12. WiFi - need more signal.

    That's the one that I use. When I had just the BT HomeHub (which is supposed to have one of the more powerful WiFi coverages) then reception was very flaky in my garden (and my garden ain't big). Using the WiFi extenders drove me nuts as they were flaky as hell. I put the Ubiquiti LR in and it's worked perfectly. Even though I'm surrounded by neighbour's WiFi networks (I can usually see 10-15 SSIDs) the Ubiquiti blasts through the lot. I'm slowly learning the lesson of Buy cheap, buy twice". No doubt you can cobble together multiple routers together, or make a router using an old PC and Linux, but the older I get the less interested I get messing about with such shenanigans. i just want solution to work well and consistently and without faffing about and rebooting the damn things every time I use them. I have the same experience years ago with networked music streamers. I railed against spending the money that Sonos charge for their kit and spent years putting up with a succession of "cheap" alternatives that sometimes worked depending on the day of the week, or that needed constant messing with, or rebooting all the time. I eventually ponied up for a Sonos device. Took it out of the box, plugged it in, 5 minutes to configure and it worked perfectly. I now have three of the things!
  13. WiFi - need more signal.

    Ubiquiti all the way then. Plug it in, 5 minutes to configure, wave goodbye to WiFi coverage issues. They do a "consumer" version that uses mesh radio. It's much more spendy, but it is good kit. https://www.techadvisor.co.uk/review/wifi-networking/ubiquiti-amplifi-hd-review-3663096/
  14. WiFi - need more signal.

    I wasn't prepared to deal with having two SSIDs or devices reconnecting when I moved from the garden to the house. Your mileage may vary.
  15. WiFi - need more signal.

    Like I said...you can have one of them. They're no good to me.
