Got a beginners' question? No matter how elementary, our friendly forum community and magazine writers will answer it.


Recently bought a 2nd hand Skywatcher 90 1250 Cassegrain (IIRC!). I knew the red dot finder didn't work - the former keeper tried changing batteries to no avail. Should I try a direct replacement (if yes any recommendations?) or should I consider something like a Seben 5x24 FS1?

Photographing the Sun Using DSLR Photographing the Sun Using DSLR

Hello All,

I'm new here and new to photographty. Eventually I'd like to do some astro photography but for now I'm sticking to DSLRs.

I'd like to know where I can buy a screw-in filter for taking images of the Sun. Is there anything available in the market.

I've searched the internet and found Thousand Oaks but I think they only do filters for telescopes.

If anyone has suggestions kindly let me know.

Newbie at 70yo!

Due to increasing infirmity I can no longer go fishing and photographing wildlife like a 40yo. I'm seriously looking to make astronomy, a lifelong interest, my new hobby. Advice seems to be towards buying a reflector scope, but what size of scope should I buy to observe the planets and close nebula? :?:

Light pollution in the Warrington Area

I was wondering whether any one else in this area of Cheshire has this problem. I can see the centres of galaxies like m81 but cant see the spiral arms. I can see 82 clearly and the divisions in galaxy's disrupted centre which is supposed to be harder to see. I have a feeling its to do with the surface brightness of arms being lower than the surface brightness of the sky. Is there ...

Am i doing something wrong

I have a Canon EOS 400d attached to my Meade 2090.

micro-lensing of Black holes

I am new to astronomy and live in Weston super mare in England.This is my first post and I wandered about Black Holes and how we can detect them. I researched about how we can and I came across Gravitational Micro-lensing as a method, where if a black hole passes in between the earth and a distant star, the background star brightens momentarily.
What I was wandering is what would be the duration of such ...

How do I adjust the sky chart for outside the UK? How do I adjust the sky chart for outside the UK?

I have recently taken an interest in astronomy and just got my first telescope. I now want to be able to use the information in the Sky at Night magazine to find objects but I live in Corfu.
Do I just need to apply the 2-hour time difference in order to use the viewing guide? And also will the monthly sky chart still be appropriate?

Sky-Watcher Heritage 90 Virtuoso and a DSLR?

Hi there,

I'm just getting into astronomy and my 5 year old son is really keen on stars and space, so I am looking for a telescope we can both enjoy (albeit with my supervision!). I am also a keen photographer and am looking to get into astrophotography beyond pictures of the Moon using my tripod.

I was looking at buying a Star-Watcher Explorer 130M or Celestron Astromaster 130 EQ MD but I was taken ...
