According to the relativistic definition of simultaneity, if two spatially separated events occur such that the light waves generated by these two events arrive at the midpoint of the line adjoining them, at the same time, then these two events are considered simultaneous. However, if these two events occur in still air, then any sound waves that might al...
Before I carry on with my 6 SE experiences I just want to thank all of you for reading my ramblings and for your comments and PMs. It is very much appreciated. I finally have some "me" time to continue the story.
The first thing I did when I got my box of goodies home was to unpack everything. A cup of tea came next.
My initial impressions wer...

I decided to try the month's free access to the Bradford Robotic Telescope on Mount Teide, Teneriffe. So thanks 'Sky at Night' Magazine! The free trial is limited to a number of given objects and the exposures and filters are all preset, so you cannot go wrong, but all in all I was quite pleased. I am considering investing the less than prohibitive £3 a...
I've mentioned a few times that I've recently bought a road bike and have started riding a lot more and I though since I've not got anything astronomical to discuss I would do this instead I bought a nice giant defy 0 bike on the cycle to work scheme and spent an extra £200 swapping the brakes, chainset and front mech so it now has a full ultegra...
It turns out ImPPG 's image alignment (via phase correlation) function comes in handy when trying to capture a video of passenger aircraft at cruising altitudes. My rig for the experiment was a SW Newtonian 114/500 (hence the coma visible in asymmetric highlights) on AZ4 + PGR Chameleon 3 mono (ICX445) camera:
So a quick blog today, just to keep things ticking over, and to keep track of my ideas etc – more for me to look back on more than anything else!
Foot is a lot better now – I am getting around ok, and have even started a new fitness ‘regime’!! I have lost 6lbs in one week, by cutting out crisps and flapjacks, and doing 20 minutes...
Hi all relatively new to Astronomy I have a StarBlast 80mm from Orion without the Syn scan hand controller!!
Has anyone had any luck using Stellarium to drive the scope without the $420 hand controller???
So the last week was kind and I managed another couple of sessions under the stars.
The lack of dark nights has made this a labor of love indeed. I have gathered 5 hours for each Ha pane so I have managed one of my bonus goals. Total integration time so far is 17 Hours:
I may not add any more data to this until the darker skies return :sa...
Hi guys , I have just purchased this telescope and it's the first one I have had. I know nothing about astronomy only I wanted to buy one to attach my Slr to it to get some good photos. I have seen the moon close up but I am having problems seeing any stars as when you look through the viewfinder nothing appears to be in line through the scope . There is...
I originally wrote this one back in May last year and since it is time of the year relevant it make sense to post now. This one has a slightly nostalgic tinge to the usual mix of pop culture references and dubious facts wrapped around a vaguely astronomical theme.
As we enjoy the longer days and the slightly warmer winter weather that here in the...
Thank you for the warm welcome. As you can guess I'm new to this. I have just purchased a Kronos 3T- 65 telescope for very little money. I purchased it so my daughter could gaze at the skies at night as she has a few issues going out during the day. The telescope is in great condition but there is two items missing from the telescope. T...
Hello, I am relativley new to astrophotography , and I have a question. I'm using a n 8 inch Shmidt Cassegrain Celestron Telescope, with a 2x Barlow and a webcam. I tried removing the lens from the webcam exposing the chip, however it completly ruined the image, I would just get a big blur of light and shadow, so I put the lens back into the webcam, and b...
It's a question that comes up regularly, but what is the difference between a Barlow and a telecentric amplifier (TA), otherwise known as a Powermate, ES Focal Extender. Meade Telextender, Bresser SA Barlow, etc? A telecentric amplifier does give a 2x magnification, just like a Barlow but that's where the similarity ends.
I would propose the material currently missing from our universe was all there at the Big Bang moment but over the billions of years much has radiated off into the void. Every star,pulsar,quasar and black hole radiate out, from birth, their contents over time. Some of the material would be retained but much would be lost especially at the outer fringe of...

It's been quite a few months now since I've been out for any serious sessions with the Telescope. However the bad habit of smoking does get me outside on a regular basis where naked eye observing was regularly taking place during those months.
My latest purchase is a GoPro Hero 4 Silver. Working in IT and having a love of gadgets the camera has opened up...
