Neptune is now close to opposition, and I would like to try to find it, and take pictures of it one night soon. I have an ASI 224 MC camera, and a CPC 800 HD Edge telescope with go-to.
I have read that at least 150X magnification is needed to see the planet adequately. What does that mean in terms of which barlow lens to use? A 2X or 3X? I can't calculate magnification since there is no eyepiece in the image train when using my camera. For those of you that have imaged Neptune with an 8" telescope, what barlow are you using, if any? From what I have read it is nothing more than a tiny blue dot, and can be extremely difficult to find. I want to get the most out of my telescope and camera, and get a few pictures of it while it is close to opposition.
For those of you that have responded to my last post on Neptune - thanks. This post deals more with barlow lenses, so please feel free to comment on this as well.
Also if any of you have captured Neptune before, please post pictures, and let me know what you are using for your telescope and image train. I am curious what is possible with different telescope/barlow/camera options.
