Today @Work, I withdrew a prefix from our AS, the video below is the prefix being withdrawn from the Internet as visualised by BGP Play which queries route collectors that send information to RIPE Stat.
I couldn’t help, but add a sneaky sound-clip to the end of the video, as the prefix disappeared from the route collectors, might make it more interesting for those who don’t have knowledge of how BGP allows the Internet to run.
Check here for information on using and interpreting the BGPlay widget.
The Perseverance Rover will attempt to ‘softly’ land on Mars later today. This is a routine that’s been tried in many ways and unfortunately has only had around a 50% success rate. Of course, we hope that through past failures we can achieve future success. Here are the Live Feeds for the landing, which starts around 1915 UTC.
Have managed to get some more data for the M33 image on the 24th December.
M33 Triangulum Pinwheel
We are now seeing some colour detail from NGC604.
Had some difficulty running from mains, seemed to trip out and reboot the Nevada PSU. Managed to overcome those issues by switching to the SkyWatcher Powertanks. I think I will have to look at a high-density LifePO4 battery. Also had some issues with the GPS detection, which might have also been rooted with the power issue.
UPDATE 29/12/2020
The issue with the PSU is that the PowerBox Advance does state it needs 10A power, I looked at my PSU and it can output 6A continuous (8A surge) – via the binding posts, and max 5A via the cigarette socket. I checked my cables and found that while the PowerBox only appeared to be drawing 2.7A for all the kit it must have been surging at times. I also found that in the length of cable from inside mains to the outside I had cigarette plugs with 5A fuses. I am now in the process of getting an upgraded PSU rated to 10A on the cigarette socket and have found a 10A fuse to use, the PSU also has a 25A-30A red/black binding posts at the back – which should suit me for any future requirements I may ever have. It also has adjustable voltage from 9-15 VDC, so I should be able to crank up the volts a little if necessary due to the cold. The PowerBox can accept 13.8V and will protect trip out at above 14.5V. The issue with the GPS seems to have been that I located it at the back of the Argon One M.2 case, and there must be some electronic or radio interference in that location. I have now been testing semi-inside with attaching the GPS mouse with Velcro to one of the Tripod legs, and when not in use I can use that Velcro strap to wind in the cable and just store the GPS mouse in the location I had hoped to be able to use it from.
Here is a recording of the Live Stream of the capture, you might want to switch it to HD for viewing and then perhaps skip through playing at x2 rate. When switching to the second power block
Here is a picture of the rig, almost completely set up – I think we just needed to run the power cable at this point. We still have some cables on order which will shorten some of the lengths and improve the cable management, but this is a lot better than the mass of cables I had running before.
OK, so the worst conception you can have about someone into astronomy, is that they sit around, outside, with a thermos flask, looking at sky pictures.
The truth is we, astrophotographers, sit indoors, during this time of self-isolation and social-distancing, trying to work out how to get the telescope to work itself.
This is fraught with problems, and a lot of the time, means going outside to check that everything is actually doing what it is supposed to do.
Quick video, feel free to fast forward, on how that process works.
This is an example of processing data of the Andromeda Galaxy, with Astro Pixel Processor. The data was obtained from the Internet, rather than captured with my equipment (cloudy and windy the last few nights).
There are some other targets available there, I’ve seen some other processed data and the nebulae are quite astonishing.
An issue I have with using practice data, is that often the data is just too perfect, otherwise it won’t have found its way on to the Internet. It sometimes is more instructive to try and process bad data and make something good of it rather than process just good data.
OK, I wouldn’t go as far as calling this an instructional video, but it is my experiemce with using APP for Multisession and Multichannel integration. Comments welcome on this one!
Recorded at the Gibraltar Private Red Arrows Show, September 2009
This is more of a test, looking at embedding more videos in the future.
