Astrophotography Help

[Edd]

Hi,

I am fairly new to astronomy, I purchased as as Skywatcher 12" Dobsonian last year and really enjoy it.

I have now decided that I would like to start to take photographs to show family and friends.

Being reasonably interested in photography; I recently purchased a Canon EOS 60D along with a Canon T2-Ring along with a Bresser 1.25" adapter.

I have been able to take some really nice pictures (Moon below)

However I only seem to be able to get an image if I attach a Barlow lens (Camera - T2 - Adapter - Barlow lens - Telescope). This is fine for images such as the one below, however I would love to be able to take pictures without the zoom. Or indeed pictures of planets which require greater zoom.

I have no idea what I need, any advice would be greatly received.

you could try un screwing the lens from the barlow to reduce the magnification just use empty barlow

Hi,

I tried this last night. Unfortunately when I do that, I don't seem to be able to focus on anything at all.

You should be able to screw the camera adaptor (minus the barrell tube bit), straight onto your scope.

The problem with a lot of newtonian telescopes is that there insufficient inwards focus travel to allow a dslr to reach focus. As you have found out if you add a barlow lens the point of focus is moved further away from the primary mirror. Your focusser may have a t-thread hidden behind the 2" adapter. This might allow the camera to be moved closer to the point of focus without the barlow.

Many thanks...... I have just been playing around with the scope and adapter and I can see exactly what you are saying.

Fingers crossed no cloud tonight.
