Ideas for guiding?

[serbiadarksky]

Well after several months spent with the StarAdventurer Mini i realised that I will need autoguiding to get longer exposures (no tracking I archieved 3min tracking)

Is there any really cheap autoguiding systems?

My budget is around 100-150€

I hope that someone can help me

Any cam with a ST4 guide port to capture the image and then PHD (which is free)  A ZWO ASI120 (USB2) is in your price range as an example. Link the cam to your finder if you don't have a suitable guide scope.

What are you imaging with at the moment?

You'll need a guide camera and some sort of guide scope, you'll need some way to mount it as well so need to consider weight.

A normal finder scope can be used to guide with.

What size lense are you getting 3 min subs from?

At the moment 600D and 50mm or 100-400mm

Currently 100mm are used at me and I get 3min exp.

Might seem a silly question, but why do you want longer exposures? With 3 minute exposure and a fast (f2.8/3.5?) lens the camera will be collecting a lot of light.

If you wish to bring out details in your images the way to achieve that is to take lots of exposures, stack them (e.g. Deep Sky Stacker) and process (stretch) the final image (e.g. Photoshop or GIMP). Longer exposure isn't always the way to go, especially as you are probably at the limit of the SAM.

Its not a silly question!

I agree with you and I decided not to go for autoguiding becouse 3min exp.is more than enought
