Celestron 10x50’s - first session. Advise wanted!
BinocularSky replied to WolfieGlos's topic in Discussions - Binoculars
I reviewed this for S@N about 8 years ago (seem to be a later incarnation of yours). 10x50s are great for astronomy and, despite its limitations, this is OK as an entry level model. If you're enjoying it, you can always upgrade later. -

Just for quick views to decide whether I think it's worth getting the PST out. -

Hmm. Might be some mutual exclusivity there 😉 -

Thanks for the heads-up. I'll see if I can figure out what's going on there. (Gave up on FF for Linux - and Windows - ages ago 🙂 ) Edit: That should be fixed now; let me know if you have any more issues with the page, & thanks again for letting me know. -
I've spent the last few months putting the new Bresser Slider Mount through its paces. Detailed review here. TL; DR: It does exactly what it says on the tin.

Lunt Mini Sunoculars 6x30 - Any Thoughts?
BinocularSky replied to Fozzie's topic in Discussions - Binoculars
I use the Celestron EclipSmart 10x25. You get to see a fair bit more at 10x, and the theoretical lower resolution of 25mm is not an issue at that magnification. -
I spy a StarChair. Regrettably, no longer made, I believe.

You're dividing the magnification, not the objective, by the exit pupil (dividing objective by exit pupil gives you the magnification). Unless I'm missing something, to get the focal ratio, you need the focal length of the objective. If you know the focal length of an eyepiece, you can work it out from that (multiply by magnification). If you're interested, there's a CN post on it: https://www.cloudynights.com/topic/13186-focal-length-in-binoculars/#entry157926
