Hi everyone, (newbie in forum).
I must be a "rare bird" because I just read the Cango thread: "Astroscope, art of the past?" and still thinking about getting an astroscope.
It is a long story. I'm looking for a dual-use astroscope; astronomy (sometimes) and birding (the most). First, I was determined to buy a Televue 85S, but it seems they have been discontinued, and, here in Europe at least, the latest units are sold too expensive (3100 €). Then I saw your photos with ED 80, especially the Skywatcher 80/600. Definitely, this image quality is what I am looking for.
Later, came Cango with his debate on new apo lens 150-600 mms. And the doubts about whether to adquire a unique astroscope or several lens, returned to me.
As I see it, it would be appropriate for me to purchase a lens like Tamron SP 150-600mm f / 5-6.3 Di VC USD G2 for walking/traveling and perhaps a larger diameter astroscope (100-150 mms) for car based trips where weight is not a concern. In this way, these diameters would really be useful for its astronomical use in deep sky and also planetary.
I have seen that some of you use this large apertures for birding, like 102 APO 700mm. Some advice in these diameters?
