Thanks for the warm welcome.
Big picture.
I think my needs right now are fairly basic and my budget is limited. I am disappointed with the quality of camera lenses, particularly focus and CA, other than that I would be happy for the time being with good optics on my double arm drive.
An apochromatic refractor is purpose built and may satisfy my 'want' of a better lens. It would get daytime use as well. But I can't see it on a double arm drive - it's probably too big for that.
Whatever I get, needs to be portable, quick to set up. Basically, I can throw it in the back of the car and go, or whip out to the front yard for an hour or so. It needs to fit with my busy schedule.
The mount needs to be accurate. I don't want something that is only good for a few minutes. My double arm drive is more precise than that. I photograph what ever I can, particularly nebula, but anything of interest. I would like better resolution of the planets.
So good quality optics, not necessarily big optics, on an accurate drive.
Camera is a Canon 1000D. I use a variety of Linux based image processing software, including imagej, but very much a beginner.
One dealer (Sirius) is offering the Orion EON 80mm and a motorised EQ3-G two axis mount and camera adapters for around AUD 1800.00. Is that a good deal? Is the EQ3 too small?
