I wouldn't consider it to be.
chemisttree said:...is a little atmospheric refraction (red edge/blue edge) so I assume that you took the pics when it was low in the sky?
What kind of camera and scope/eyepiece did you use?
On the Moon, you can align in Registrax using a crater with good contrast most of the time.

Notice the dates on the pics...that's the big problem, when you light the fire you need more...
Chronos said:Thanks a lot, guys, I just purchased new scope, ccd, and accessories. Only spent twice as much as planned [and still short a few extras]. I won't be ordering out for pizza in the foreseeable future. I will, however, be able to take beautiful close up shots of neighbors' pizza ... putting up sign next to scope - 1 slice per observer.
I'm not really sure how it works with DSLRs, but the math on that works out to 6x zoom. That's marginal, but should be OK for a start.MikeyW said:Thanks Russ. Is 200mm long enough? I really only have a choice between a 55-200mm and a 70-300mm in my price range. The former would be much more useful in other areas, and it has VR.
Plus the camera has 1.6 crop factor.

The camera part is dangerous - once you rip the lens off a webcam and slap it onto the back of your telescope, there is no going back!
Sorry: Venus.MikeyW said:Hi all again.
Was just wondering what this object is in the night sky.
Please tell me it's Mars!
I'm not sure what you mean - could you rephrase?Also I think it might be interesting to note the "sunstars" that I got out of the camera from the road lights are not also present on this object- why?
adyarbakery said:hi,
I took these photos of the sky from Yosemite.

I found that there were streaks on the image - which could be a planet, comet or a meteor. I know it is not a planet (I checked on stellarium for that). However I can not figure out if it is a comet or a planet. These are 8 second exposures. Any idea if it is a comet or a meteor?
I tend to gravitate towards it being a comet, since it was in the sky for an extended period of time (photographs taken after 5 minutes later also showed the streak).
Any ideas how to figure out?
thanks,
