  1. @Xiga - that is a fantastic tutorial, some really great techniques in there, thank you for sharing. Great picture too, well worthy of the win! Congratulations!
  2. This data set has been sitting on my hard drive since last summer, waiting for the right moment... well that moment finally arrived. Here is my image of The Iris Nebula (NGC 7023): While gathering the data I noticed that loads of subs were photo-bombed by space hardware. I thought it would be interesting to do a stack that didn't remove any of the trails and here is the result. Yikes! I haven't counted how many there are, but it seems to be hundreds... The image comprises 3 hours in each of R, G & B, along with 13 hours of Luminance. A total integration time of
  3. Thanks Rodd, I will brave the system again and see if I can get a bit further. With regards to filter naming, I was under the impression that V stood for Visual, i.e. around the Green wavelengths. I like the idea that it stands for Verde though.
  4. Superb images and an interesting project. Do you have further information about which filters were used for the data here? I have briefly looked at the Hubble Archive, but not yet fathomed what to look for to create a colour image. All help gratefully received!
  5. I totally agree with the OP, too much data would be a problem. I currently have six full data sets [Ed. when has a data set ever been agreed to be ‘full’?!!?] sitting on my hard drive waiting to be processed. I just struggle to find the time to sit down for the hours required to do a data set justice. Especially at the moment with so much screen time for everyday life, the last thing I want to do is spend more time at the screen. So, on the one hand, thank goodness it hasn’t been night after night of clear skies in the UK, on the other hand, it is totally depressing that there have been only a
  6. Exactly, double click the vbs file for the rate that you want to set. Give it a go!
  7. The vbs route is very simple. You will find a folder of standard vbs scripts in a folder here: C:ProgramData/SiTech/SiTechExe/VBSScripts (see screenshot). You just double click the script you want to run, e.g. LunarRate.vbs and it will change the parameter. A dialog box appears telling you what the current setting is and you just click OK. Don’t forget to run SiderealRate.vbs to put it back to sidereal rate when required! Hope that sorts the issue out for you.
  8. Exactly how are you setting the mount to Lunar Rate Tracking? I have a Mesu 200 and to change the rate setting I have to run a vbs script. You don’t describe doing that anywhere. It very much sounds like you have not really set the mount to Lunar Rate...
  9. I am currently live streaming the output of my GRAVES radio meteor detection system on YouTube and the Quadrantids meteor shower is very active! Have a look here:
  10. Thank you for this Olly. I wasn’t worrying about it until I watched this video and developed ‘balance envy’!! I will stop worrying again now.
  11. Thanks Ian, yes, the kit is glowing! The aerial is on a 3 metre mast. It is at an elevation angle of only about 10° as the ground is uneven. I will do a bit of gardening to drop the back foot of the tripod to raise the elevation of the aerial a few degrees. I have reduced the gain and upped the SNR threshold; the system is now registering proper meteor events only. I’m ready for the Quadrantids!
  12. Could the intermittent line be occasional reflection off the ionosphere?
  13. The continuing story: I moved the aerial from the Warm Room to outside yesterday and the radio sky has exploded into life... and it was pretty busy before! I am finding that it is regularly detecting an almost continuous stream around events. Is this just lingering ionisation or might it be the direct GRAVES signal itself? I can't belief it is the direct signal as geography suggests that is not possible. My best interpretation is that the system is now massively more sensitive. I have reduced the Gain right down and altered the SNR threshold up slightly. I will see if that calms things do
  14. Nice video, thanks for posting! That looks ultra easy with the ASA mount. I have a Mesu 200 and the software doesn’t have that balance feature. I have balanced as well as I could manually. Any ideas about a software solution for direct drive mounts other than the ASA?
  15. Looking through my data, I have found some more probable ISS events. This is a little earlier from the same 18-12-20, 12:40 pass: And one from the 07:50 pass this morning: And finally, a noisy one from the 13:27 pass yesterday 17-12-20: The ISS 'ugly' orbit is obviously just in the right patch of sky right now, so no doubt more events to come.
