If it's in the process of falling then it is not in orbit any more.
If it were still in orbit then it wouldn't be falling.

It may be orbiting the planet as in going around it as it falls but I wouldn't count that as the same.

Very nice idea, just one small point you are posting on SPA about joining the BAA VSS section. :o

Look at the top of the pages and you will see a SPA VSS section. :shock:

Slightly indelicate. :roll: :roll: :roll:

The person travelling seems to be slowing down to an external observer. The external observers time is still going at the "normal" rate. To the traveller the people outside seem to go faster. The traveller just sees themselves moving at the "normal" rate. Whoever is "observing" only sees themselves ...

For DSO's the normal route is to take exposures that are in the minutes. So 20 exposures of 5 minutes duration each is quite common. That cannot be done with a web cam as best I am aware. That being the reason that either dedicated ccd cameras are used or the good old DSLR. Field rotation at these t...

If you read the various forums they are presently splattered with several posts of problems relating to the Synscan system. :shock: It would seem that there could be a quality control issue somewhere. At this time I would not consider upgrading either of the 2 EQ mounts I have to Synscan. :cry: :cry:

The Evostar 90 is a nice scope, don't rush to get bigger, that one will last for years and will do most of what ever you want. A nice choice. Which area of Essex are you? There are several clubs and just wonder if one is close enough that driving is not necessary. Saturn is around at present, not ov...

Did the same last year. For 3 days I got up, went out the door, looked South and saw a nice red star, got in the car drove to work. Spent all 3 mornings looking at it and each morning trying to work out what it could be. Really should have dawned on me. Especially as I consulted a book or two and a ...

Rachel, would agree with you that wanting to chat astronomy is good. The heading at the top of General says: Talk with fellow astronomers about anything under the stars - as long as it is astronomical. Have you looked at the topics in General? :?

Many astro societies seem a bit excluding to women. One group local to me is excluding to just about everyone, male, female, martian, that hasn't been there for 3+ years. Oddly another I visit has a large proportion of women there. Will say that it is as much a "social" meet once a month, but a lot ...

The sentiment that a goto is not essential is correct. But neither is a PC nor a car, the internet wasn't a common thing only 15 years ago. My goto is 11 years old, so reasonably close in time. PC, car and internet is considered essential now. Situations change. My one concern would be spending the ...
