Re: Brand new and frustrated

Which of the constellations do you know? To find anything you have to know a few of the basic ones. The Plough (asterism not constellation in reality) is likely the first to work out. This then can be used to point at ot at least towards others. Then work out where Cassiopeia is (sort of big W thing...

Re: Astronomy for beginners.

To me the big problem is - define astronomy. Visit a university with astronomy as a post graduate area of research and you start to realise that "astronomy" is not looking up at stars and going Ooh and Aargh. Question here - Was it ever ? For people now I would expect that you will have to explain m...

Re: upgrading eyepices

Really first question is what is she willing to spend on you? Eyepieces come in assorted costs. The ones you have will be MA's or Kelners I suspect. The 2 sort of standard first steps are generally the BST Starguiders £49, or the Celestron X-Cels £59. Performance is reported as pretty close to ident...

Re: cameras

Before you jump be aware that you have bought yourself a nice visual scope, the unfortunate aspect is that this does noit necessarily mean a good imaging scope. Simply the requirement's are different. You will see more (should see more) with the 200P on the EQ5, however you would image better with a...

Re: Refractor or reflector

No filter will turn an Achro into an APO, or even a decent ED refractor. If they did we would not spend money on a triplet when a cheap achro (ST 102) and a £50 filter would do the same. Not sure what the Baader is but it will either filter out one set of wavelengths - so upsetting the actual colour...

Re: optics

With glasses you will want 15mm or more in eye relief. A plossl does not have fixed eye relief they have eye relief of about 2/3 the eyepiece focal length. So that is a point to be aware of when purchasing that type. Magnification is: Scope focal length/eyepiece focal length Your scope is 1000mm so ...

Re: Giving up Astronomy

Where about are you? I assume the UK but no hint at a location, I ask as there may well be a club relatively near you that has a night to go along and get a helping hand. Many do them and this is the time of year they are held. Trouble is without some indication it is not possible to suggest anywher...

Re: Astronomy accommodation in Cornwall

Looks interesting, my only "problem" is the lack of where it exactly is. A postal address and a post code would help enormously, that way people can look up precisely where it is located. Google maps. I can get Bude and Windsor Farm, but that is all. How far and which direction Windsor Farm is from ...

Re: Telescope choice

The only one that might work well is the 10cm f/9 APO refractor, even then you would need a good mount and a reducer. The Newtonian is too big any breeze would ruin an exposure, you would also need a much bigger mount then HEQ5 to hold it as well. The Mak and SCT have too long a focal length to be u...

Re: Instruction booklet needed pls

You have a 4" reflector that is defined af f/10.8, this comes from dividing the focal length 1100mm, by the diameter, 102mm. It is likely a spherical mirror however at f/10.8 that should not cause any troubles. I cannot locate a manual, did locate a Youtube vid to set one up. http://www.youtube.com/...

Re: Still Problems with Finder

If you have the Evostar 90 then don't worry it is a good scope. Actually one that I would say many should start with and quite a few need not consider an upgrade. It will cover most things very well. The finder, first really is can you adjust it and get it to remain stable. If not sit down with it a...

Re: Space Time

Not easy to explain and really I am not going to try. I would forget and relation between distance and time. That was true until Hubble found everything was moving away from us then they discovered that this movement was not the objects but the space-time that wwas expanding. It has taken the light ...

Re: More Telescope Problems

If in Exeter you are close to the NLO in Sidmouth and I think there is a meeting of astronomers there every Friday. The observatory is just outside Sidmouth, Eastern side and up a damn great hill. That would be the most direct solution I could think of. It does of course assume that you can drive th...

Re: Can you find an error in the theory?

Who said the solar system is stable? We have only had an idea about it for a few hundred years, the timescale of the solar system is measured in the odd billion or two years. Not long back Einstein was told that the universe was unchanging and fixed, now we have changed that idea and not only is it ...
