First Image of 2017

     It wasn't the greatest night for imaging, but this was my last chance to capture Mars and Neptune in the same picture.  This image was taken with my Tele Vue NP101 and Canon T3i.  Actually I think the haze might have improved the image.  If you look closely at Neptune you will see a tiny speck, that isn't a star,  it is Triton, one of Neptune's moons.

 

 

 

    


ISS Transiting the Sun

This past summer I was told of a great website (ISS Transit Finder).  Inputting your Lat. and Lon. it will calculate if and when the ISS will cross between you and the Sun, and Moon.  So I punched my data and "bingo" there was going to be a pass, actually 2 passes came up, a week apart.  I decided to try capturing this event.  Well the weather wasn't good for the first pass, but I set up anyway.  I set up my Lunt LS60-THa solar scope with a MallinCam Micro ex.  What I needed to do is capture a video of the transit.  The actual transit takes less than 1 second.  in this case it was .54 sec.  Even with the skies so poor I figured I would try a test run.  I wasn't even sure how accurate this info was going to be.  I had a few friends over to witness this event.  Just as it was time for the transit the clouds thinned a bit.  We didn't see a thing.  But after playing back the video we did catch a glimpse of the ISS.  Wow, this actually worked.  The fallowing week the weather was perfect.  I was already to go.  I was sertup like the previous week with the Lunt solar scope.  I started capturing the video and with in a second there it went.  
I took the captured AVI video and used the 20 frames that showed the ISS transit.  Using RegiStax this is what I was able to get.  Next time I will speed up the frame rate of the camera to get a better image.
 

Imaging in Ha


Its been a while since Ive posted any images. Sorry.   This past fall I started imaging with a 12nm Ha filter. This type of filter only allows Hydrogen's deep red light to pass threw to the camera.  This is very useful for imaging very faint nebulae. Even under moon lit skies.  The only drawback is you need to double your exposure times or double the iso.  These images where comprised of 10 min. exposures @ 1600iso. In processing the images where converted to grey-scale,   and then some where colorized red.
