Got a few hours of clear skies last night.

Managed to polar align in pretty much 3 mins.

Again I have been sticking to my target of M45, really because its very easy to find :)

For me the weak point on this system is the ball head. I find it difficult to move it around and position the target.

Im thinking I might invest in the Astrotrac wedge and move the gear head into the ball head position. the slow motion controls will make things better I think.

I tried a 72mm William Optics APO on this set up also. And again the ball head let me down. It was slipping badly. In fairness I did expect this. But if I buy an expensive large L series lens i wonder if i would have issues.

Lastly, and this maybe just me, I freely admit that my knowledge of the night sky is not brilliant, I find myself missing GOTO.

I have compiled a list of 5 targets I would like to shoot over the next few months and feel I may waste a lot of time in looking for them. Not having a finder-scope is a loss I feel.

I have seen on TS website that you can get an adapter for the flash seat on a camera to fit the clamp type red dot finder. Its not expensive and might help me a lot.

Anyone experienced this kind of problem ?

Astrotrac Wedge arrived. Its a very solid looking bit of kit. Less than 24 hours between ordering and delivery! Kudos Stephen! :)

Now if the sky would just clear.

Picture added. The wedge makes this set up very stable, and allows me to put the gear head under the camera.

I can't tell how well it works but I've seen a number of examples of relatively substantial loads being put on an Astrotrac:

wow, that is serious weight.

Looks like thats a different machine head than the Astrotrac one. Im not surprised. Its more expensive than the Wedge!

Nice one Dave,

'But if I buy an expensive large L series lens i wonder if i would have issues'

I don't think so, I have a Canon 70-200mm L lens and it is quite heavy, I have never had a problem with slippage or balance yet, but I do agree that the ball head is not ideal

Keith..
