Hi Ben... It allows you to view brighter objects without being to bright... The moon for example is pretty glarey when full.<br />

do not look at the sun though. You need a specific filter for the sun!

Thanks alot!

Like i asked Acey, would it make viewing planets and galaxies like M31 easier to see?

It's for viewing with a reduced aperture, set off-centre because the secondary would block it if the hole were in the middle. Usually used for solar viewing (with safe solar filter over the hole).

Thanks very much, in what way would it help with solar viewing?

would it help to make planets and galaxies like andromeda much clearer? please can you explain?

Hello, My name is Ben,

When i brought my Celestron NexStar 130 SLT Scope IT had dawned on me that the main scope cap has a hole in it with a removable cover, Would it be possible for someone to tell me what it is?. I have included a picture below.

Regards,

Ben Rolfe
