Right now I'm looking to get myself a binoviewer, but I don't know which one to get. If I get one, I'll want to use it with my 12" f4.9 dobson telescope both for planetary and dso observations.
I'm currently looking at:
- TS-Optics standard BV - $200
- TS-Optics big BV - $400
- Baader Maxbright 2 - $500
- TS-Optics 0 path length BV - $400
My problem is that I can't see the use of a big and expensive bino for my setup with a large diameter clear path. If I won't be able to avoid using a GPC with my dobson, which will increase the focal length of my telescope to a point that my 24 Panos will effectively operate at 12-14mm, then why bother with a big binoviewer?
A less expensive standard bino from TS with a clear path of 21mm is plenty for the Panos in this configuration.
Using a conventional binoviewer with a dobson telescope for dso observations is in this regard also a bit of stretch because I won't have a high enough focal length left in my eyepieces for a wider FOV.
The TS-Optics 0 path length binoviewer is an interesting choice because it will allow me to use my eyepieces without an extra magnification from a GPC. The clear path on that binoviewer, however is only 22mm so I can't use the 24 Panos without experiencing vignetting, which is also bad.
I feel that there isn't a good choice for a binoviewer, if it's intended for a dobson telescope and that my best bet is to go with the standard binoviewer from TS-Optics.
Am I missing something? Any feedback is welcomed.
