hi everyone:hi:,

i'm 14yrs old and am very interested in science especially the astronomical side of it thats why i'm an amatuer astronomer:D.

What i want to find out is in what kinds of ways can i contribute to science by doing visual observing with my 5'' reflector and i'm in the market for a 10'' dob so hopefully that helps.

I've heard about variable star observing but i'm a bit scared of the fact at trying to get the mags visually and i have limited equipment basically just my scope and eyepieces.i love sketching what i see at the ep so anything including sketching i will love.

I'm currently reading lots about astronomical topics trying to expand my knowledge but i thought maybe i could do some practical work too, to help me out.

thanks in advance

Hi Orestis, you might like to join in on this conversation.

Variable Star Observing- What's Involved? (http://www.iceinspace.com.au/forum/showthread.php?t=63964)

Hi Orestis! I reckon you'll take to variable star observing like a duck to water! We've all seen your sketches - that's exactly the sort of thing that provides an excellent lead-in to visual observations, because your eye has learned to discriminate subtle differences in brightness.

Check Suzy's thread for lots of good links. AAVSO is the best starting point. :thumbsup:

Cheers -

One of the best pieces of equipment you can use for keeping an eye on variable stars is a good pair of binoculars and/or a short focal length scope...like a small refractor. You use the binos to get a good look at a wide field and then zero in on the star with the scope. But even the brighter variables are quite amenable to observing with binos. Once you get a good eye in on discriminating the brightness differences in stars, you can then track any changes in brightness for many variables.

Ultimately though, you'll want a good scope with an EQ mount so you keep track of your star and a photometer (http://www.optecinc.com/astronomy/ssp_main.htm) to measure any brightness variations. Quite a few variables can only be measured using sensitive equipment because their variations are so small and/or rapid. You'll also have the added benefit of being able to track transiting exoplanets as well, with the right gear.

You might want to consider stellar/lunar occultation work. You need an accurate means for determining the time though ie you need access to an accurate time service or GPS based PPS source.

Thanks guys for the suggestions:thumbsup:.
Can't wait to see what sort of obs i can make.
