Moon, Venus and Mars Conjunction, Jan 31, 2017

Moon, Venus and Mars on Jan 31, 2017. Canon T3 and a Canon 200mmm telephoto lens set at F/4. Exposure was 1/100th sec @ ISO 3200.

A beautiful conjunction of the moon and two planets made the last evening of Jan 2017 quite nice.  The Moon joined Venus and Mars on this evening and I just had to get some shots.

Moon, Venus and Mars on Jan 31, 2017. Canon T3 and a Canon 200mmm telephoto lens set at F/2.8. Exposure was 1/40th sec @ ISO 3200.

I could have used a tripod for these, but I took the images by propping the camera on the top of a car.   Consequently, I had lots of rejected images due to motion blur.    But, luckily, I got a three steady ones that were good enough to post.   The forth image below was a repair job, but it came out OK after correcting it for my unsteady hands.  🙂

These last two are actually composites.   The one right above had motion blur and as mentioned previously, I was able to fix it.  But, fixing it messed up the trees.  So, I had to composite the good trees back in from the original.  In the second image above, the moon was replaced with a better version from the 200mm lens.

 

Comet Siding Spring Meets Mars

C/2013 A1/Mars Encounter, Oct 19, 2014. 10 x 180 sec @ ISO 1600, 20 x 60 sec @ ISO 6400, TV-85 at F/5.6, IDAS-LPS, Modified Canon T3.

Update October 20, 2014:  The above image is an update with more time added.  Compare it to the image below which was made with only 20 minutes of data shot at ISO 6400 (20×60 sec sub-images.)  I took an additional 30 minutes of 3 minute sub-images at ISO 1600 and added it in, so the combined total is 50 minutes.

Well, the big comet encounter of the year took place tonight, Oct 19, 2014 and Mars and Comet Siding Spring (C/2013 A1) both survived.  LoL.   Seriously, it was a very close encounter if you had darkness when it was closest.  Here in southern Louisiana, it took place during daylight, so I had to catch it after closest approach as C/2013 A1 was bidding Mars farewell.

I had a strange night with some issues, but I managed to get some decent data and also lucked out with some good weather for this event.  This image is from the first set of images I took and it is a composite of comet-only processed and star background processed image stacks.  The comet moved a good distance in the twenty-five minutes it took to get the sub-frames, so I had to isolate it with different alignment and stacking techniques than I use for normal deep-sky images.
