Please Advise

I was out earlier looking at Jupiter & Venus.

This is a photoshop from my memory not actual from the telescope.

My question is that I could not get a perfect disc of Jupiter and the more powerful the eyepiece the worse things became. I can only put it down to the scope itself as my Celestron 17 x 50 Binos produced a smaller but more pleasing observation.

Note the blurred red and blue colours. Your advise please wonderful people?

It could be seeing conditions.

Jupiter is low down so you are seeing through atmospheric conditions.

or

if you are using a dob your colllimation is out.

[kniclander]

the blurred red and blue is due to poor seeing not poor collimation (but that is not to say that poor collimation might not be an issue too)

what scope is it?

Thank guy's

Its a cheapo £160.00 Meade 2090 refractor with auto star.

Sorry should have said.

[Doc]

refractors are normally collimated and need no adjustment. Not always but normally.

I put money on it, the reason is seeing conditions.

Agree with the others - Jupiter is very low in the sky, and therefore you are looking through alot more atmosphere than if it was straight up. Added to a turbulent atmosphere, and things can appear to 'dance' in the eyepiece.

If things are like this, then the seeing is bad, and the only thing you can do is reduce the power - it will get worse the more power you put on the object.

Also - did you really see blue colours in the eyepiece? If so, you might have been slightly out of focus as well.

Cheers,

Richie

I'd have said it was the conditions too.
