First binoculars--recommendations?
Sedna replied to Sedna's topic in Getting Started Equipment Help and Advice
Thanks, sorry for the very slow reply ... is there a specific make/model of 10x50 you recommend? -
Hi all, I'm worried that my Celestron VX equatorial mount might be broken, and I wanted to check here to see if anyone has had a similar problem. I've had the mount for seven months. The first time I noticed something weird was a few months ago when I slewed towards an object that was nowhere near the horizon and the mount started pointing my SC tube *below* the horizon! I turned it off quickly so it wouldn't tip over. Second time occurred about a month ago, another strange incident: the RA axis had rotated more than 90 degrees (which I don't think should ever happen?!) and I had to grab the t

First binoculars--recommendations?
Sedna posted a topic in Getting Started Equipment Help and Advice
Hi all, I'm looking for recommendations for a good pair of binoculars. These would be my first "real" binoculars used for anything. I generally observe with my Celestron 8SE and own a laughably cheap pair of binoculars. I'm not sure whether to go with a heavy pair that require a tripod (but thus cannot be used to observe the Zenith) or a lighter pair that I can point straight up but have less magnification/quality. I prefer not to go too much over 100 USD, but I could go up to 200 USD if someone has a really great recommendation. Obviously I'll be using these mostly for astro, but would likely -
Ah, sorry about that, didn't realize they were JPEGs. Okay, how about trying here instead. If you scroll down to Pluto Encounter, everything under LORRI (New Horizon's high focal length black and white camera) and MVIC (the low focal length color camera) should be relevant. Please let me know if you need any more assistance!

When New Horizons flew by Pluto and Charon in 2015, each body had one hemisphere that was never mapped at higher resolution than what we see in the images below. Because Pluto and Charon rotate relatively slowly (6.4 days), only one hemisphere of each was facing New Horizons during its closest approach. Will we ever see the other face of Pluto (or Charon) mapped in high resolution? The face of Pluto that was mapped in low-resolution is the hemisphere that is tidally locked with (permanently facing) Charon. From New Horizons low resolution imagery, we see that it is very

Is ZWO Asi224mc a smart choice for Mac OSX and Celestron 8SE?
Sedna replied to Sedna's topic in Getting Started With Imaging
Thanks James! How much of a showstopper is the issue with saving SER files? I imagine I would want to save mine as AVI, in which case it shouldn't matter? -

Yep, I also asked on there. As to why they never updated it, go figure. -

Thanks for the link. Is ASI224MC a color camera or monochrome? I am super confused because there is conflicting info in the description on Amazon. The product title says color and info at the top says color camera, but further down the page it says monochrome?! -
