Trouble viewing anything other than the moon

Postby Bawl » Fri Aug 31, 2018 1:06 am

I have only recently got my first telescope so I may somewhere be making a easy mistake but I thought it would be best to ask I have gotten some great days looking at the moon it looks amazing but when I look at something say mars I can see the support and a black spot in the centre I know that my eyepiece is focused I am using an Orion SpaceProbe 130ST Equatorial Reflector Telescope and I have tried viewing mars with a 4mm, 6mm and 10mm all of which are giving me the same problem?

Hi and welcome.
If you're getting good focused views of the Moon with your scope, there's nothing obviously wrong with the optics.

I suggest you start with getting a good sharp focused image of the Moon - and then swing to Mars without adjusting the focus (or changing the eyepiece) it should be very close to properly focused as well.

You'll get the 'support and central obstruction' image when it's a long way out of focus, so it sounds to me as though you're looking to focus, but moving away from where you should be...

If the Moon's not up, any bright star (or preferably) star cluster should be sufficient to make sure you have a sharp focus before you move over to Mars. When you have a good image with the original eyepiece, you can then try moving up the magnification scale by moving to shorter EPs.

Just be aware that Mars is small - only about 21 arc seconds across.

How big is this?

If you get to look at the Moon tonight, you should be able to make out the crater Aristarchus on the left. Mars is about the same angular size as that crater.
Here's where to find it.

:)

With a scope like yours, look for Open and Globular clusters. Also, some of the larger Planetary Nebulae.
It's a pretty good time of year, as we have several targets in (or near) the "Summer Triangle", and later in the night the 'Autumn' constellation(s) appear

Still haven't been able to test this as the sky has not been clear

Nothing more annoying than getting a new telescope and then the clouds roll in!

I think out of the almost 3 months I have had the telescope I have only been able to you use it maybe 10 times and most the time it always covers events like that lunar eclipse and it almost ruined the full moon but I got a good shot
