  1. Entry level canon and EOS utility (with a netbook or laptop) is cheap and effective. Plus canon cameras have a much wider support base in the astro community (regarding software and modifications).
  2. Why not use a more dedicated remote utility? Something like teamviewer or tightVNC? That would solve your problems in a single stroke
  3. I use registar for the same thing. Though it's sensible to use a colour sensor that's larger than your mono (so no mono data is wasted). It's also possible to combine different focal lengths and telescope types. This is data taken using a star 71 (widefield) and a 200pds and 130pds (newtonian) for high res details:
  4. 80min on the Jellyfish, between rain showers last weekend:
  5. So far its a negative, though Ive since found a different way to connect it - but I wont be able to try that out until tomorrow.
  6. Oh, for a quick check I just used a cheshire inserted at the other end of the self centreing adaptor and the crosshairs indicate that the middle of the lens is indeed central.
  7. Yeah, there are the manufacturing tolerances - it could be way off, but if works it will be one of the all-time top bargains! I will double check it with a cheshire to see if it got close.
  8. Cheers, cant do it until the kids are in bed otherwise there would be just too many "little hands" touching things they shouldnt...lol.
  9. I was idly browsing the internet a couple of hours ago when I stumbled across this: https://www.wilko.com/en-uk/wilko-high-resolution-webcam/p/0460186 That particular camera looked almost as if it was a good fit for a 1.25" EP holder, so after work I popped out and grabbed one for the glorious price of just 8 qui!d! So once I got home I opened the packaging and the front lip of the focusing ring *just* about fits into a 1.25" ep holder (with no wiggle), but not far enough for the thumb screws to lock it into position..... sooo looking around in the bits box I found a self-centreing EP adaptor, which when fully unwound allows you to fit it in by a few mm. All I had to do then was apply a little downward pressure whilst tightening up the adaptor and bingo.... it stayed put. It works straight off wiith sharpcap (under W10) and looks like it will do a decent job of centreing a secondary mirror, maybe good enough for total collimation. I wont know until I try it later this evening.... but for 8 quid its worth a punt! I might use Al's reticle though, because the one in sharpcap cant be configured (I want the drawtube to stay in its imaging position while collimating).
  10. Remarkably, there has been a good run of clear skies which coincided with the nights I havent been working (or too tired...lol) so time to have a tinker with the 130pds being as that will be my main imaging scope for the next few months. Good thing I took it apart as the secondary was filthy, gave that a quick wash before putting it all back together with the milk bottle washer mod. I knew this might be my only chance at an image for a bit, so I just left everything at 2x2 bin to make the most of limited time and still get an acceptable image. Could do better with more time, but aint that always the case! Also there were some stacking and calibration issues so I had to crop a bit of it, I think the OIII data needs its own set of flats (I applied Ha flats to all filters). 130pds, NEQ6, 683WSG 25x450 (Ha), 10x450 (SII_R, Ha_G, OIII_B) Thanks for looking
  11. Still working on this but its looking promising, even with absolutely no calibration frames:
  12. With a big telescope (625mm aperture), a barlow, and: This, for building the video: http://www.spaceyes.com/en/products/spaceyes3d-builder.html And this, for importing NASA geographical data: https://en.wikipedia.org/wiki/QGIS
