Camera lens or an apo refractor?

The new Sigma 100-400mm f5-6.3 looks interesting and has received excellent reviews. It's currently retailing for £799. I figure you could get a 2.5" triplet apo refractor for the money. The lens of course offers autofocus and stabilisation on top of the variable focal length. But the refractor would have better contrast for astronomy work.

Thoughts? (I've already got a 66mm doublet refractor.)

where to locate the Barlow?

I lost my post !

Starting again
I have bought a refractor to replace my not good 6" Newtonian.
The scope has a 2" focuser, and I ordered a 2" diagonal and a 2" Barlow.
What order do it place the diagonal and Barlow?

Focuser > Barlow > diagonal > eyepiece
Focuser > diagonal > Barlow > eyepiece

The Barlow came with 2" to 1.25" adaptor, so I can use either 2" or 1.25" ...

Telescope cases


I am a complete beginner and have no idea what I'm doing, but I have decided to buy a telescope and have settled on a Skywatcher evostar 120 with an eq5 mount. I guess my first question is do I need a case for both the telescope and the mount?

I will be taking it in my car to get dark skies so I assume that I do for the telescope as this is ...

Newtonian Spherical Projection System

I recently purchased at auction an entire projection system from a university. It's all from a company called "spice automation" from what I can tell it's from 1992. I have no idea what a good place to get rid of some of this equipment would be or even what it does. Right now I have a Newtonian Spherical Projection System about to go on ebay tonight, but as for the rest??? anyone ever heard of ...

Beginners telescope & book recommendations, please.

Hi, I'm looking for a telescope for my daughter's 9th birthday. She would want to be able to see details of the moon and also the whole moon, stars and ideally some real 'wow' views.
She is also a keen birdwatcher, so one that can be used for that too, would be great. However, if it really meant she wouldn't get such a good view of the night sky, then we may reconsider this aspect. ...

Astrophotography Beginners Equipment Help

Hi all,

I am sure you get this a lot, and I have read a few posts and articles about starting astrophotography and it seems it can be done step by step which I think I will need to do.

Basically, I can invest a bit of money at a time, but not all at once - I know I will have to learn and work towards those amazing DSO images and it's going to ...

Hi all,
Just joined and interested in starting some stargazing. I've read online that is best to start of with good binoculars then move onto telescopes.
Can anyone suggest a good pair of binoculars for stargazing?
I have looked myself and came across "Helios Fieldmaster 10x50 Binoculars" and "Helios Fieldmaster 7x50 Binoculars" but again as Im new I don't know if any of these are suitable.
Any help would be greatly appreciated.thanks

Hi, I have a celestron nexstar 130 slt and i am looking into buying a dslr mainly for astrophotography. I realise that i will probably need to buy a 2x barlow in order to solve focus issues but does anyone have any recommendations? I have about £400 to spend, including the barlow and any adaptors, but i can go over if its impractical to get decent photographs in that price range. Thanks for any suggestions, ...
