Hi Rick, I'm gonna be 65 and I used to have wicked-good eyes. Not anymore. And dashnabbit, you're lucky if your wisdom is increasing! The only thing my wisdom has taught me is how little I truly ...

Something looks off on the D5300 single black frame... Don't worry about battery life.  If you are serious about doing this the right way in the cold, you will power the camera off a larger ...

Hi Duy, Unfortunately, stars at infinity need to be actually focused at infinity. Depth of field is not going to work here. So if you have a wide-angle, and have something in the close foreground ...

I don't want to rain on anyone's parade, but converting from 8 bits to a higher bit depth doesn't magically give you any more actual information. If you are going to stretch the data, you really ...

I really enjoyed reading this thread and want to thank Roger for his generosity in taking the time for such detailed, expert posts. Jerry

Thanks. :-) And the amazing thing is, even fully packed with camping and astro gear, I can still keep the rear view window clear so I can see out of it. It's a heck of a car for reliability, ...

No, I'm saying I carry everything in that picture of my equipment every time I go out to my close observing site. I don't necessarily use every single thing every time I go out, but I can't tell ...

Thanks! Oh, I'm intimately familiar with my babies. I know where everything is. Jerry

Nice. Jerry

Hi Ollie, There is much to be said for the simple life. :-) Jerry

I'm half way through my dostadning now. Jerry

Here's what's in my bag... Equipment for a single night of astrophotography. More info and the 182 megabyte full resolution 16,565 x 11,016 image here: http://www.astropix.com/html/i_astrop/eq_test ...

A better f-stop? Not sure what that means... a wider f/stop? A smaller f/stop? In any event, a wider f/stop with a faster focal ratio is better (if you lens doesn't have serious aberrations wide ...

Yes, the cheap version of SkySafari for Android should show what you need. You can input any location and time. Jerry

Rey, What focal ratio did you shoot this at? Wide open? "Why spend that much money on all my beautiful glass and then stop me down?" the 200/2 asks as it screams in silent pain at the thought. Isn' ...

Deepsky stacker may be having trouble also because of the quality of the star images at the corners of the frame. Those stars on the fast lens are not round points. Did you have this problem with ...

Focusing with Live View is pretty easy if you do it right. It's pretty much all I use anymore. Here are some tips to help you... http://www.astropix.com/html/i_astrop/focus/live_view_focusing.html ...

Hi Mark, Great report! Does the D5300 show HPS spatial filtering on exposures taken with Bulb? Jerry
