Hi Adam

I see that you are using a 10" LX200 @ f10 plus a 2.5x Barlow, so your effective f/ratio is f25. The magnification is around 125x, you probly can increase your f/ratio to f30 or high. Important tip with barlows, buy one that has optimum aberration control such as the UO Klee 2.8x ot the TeleVue Powermate. Other things to consider is collimation, temperture of the scope, weather etc.

I see that you use the LPI, it is a good beginner camera. When you have mastered some of the basic I would recommend upgrading to a camera similar to the Lumenera or the camera that Bird is currently using. They are well worth the money and you will have so much fun.
