My First Astrotracer Images (1)

(2012-11-10 / Last updated: 2014-05-03)

 

July 2012 - September 2012 (Very first images)

July 2012 - March 2013 (New FA 50/1.4 lens & first smaller galxies)

July 2013 - October 2013 (New DA 200/2.8 lens and 'new' A 2X-S converter)

November 2013 (Very, for Astrotracer, long focal lengths)

December 2013 (small 'victories': The tiney and Dim & old places revisited)

April 2014 (Tiny Galaxies - Testing the O-GPS1 on PENTAX K-3 DSLR)

 

July - September 2012

These are my very first Astrotracer images taken during summer and autumn 2012 using the Pentax GPS Unit O-GPS1 on my Pentax K-5 DSLR. They have been shot mostly under rather lousy conditions: My sky was very, very bright during Nordic summer and autumn images were mostly shot from my fourth floor balcony in the city under a heavily light polluted sky. Weather hasn't been very co-operative this year either!

Needless to say such conditions require as well stacking as post-processing which I have described elsewhere in my tutorials on subject of post-processing.

I am still experimenting and the images below are representatives for the extremes of the lenses I currently use together with Astrotracer, namely 50mm and 350mm. 50mm is fairly easy and straightforward with Astrotracer; 350mm on the other hand is certainly at or near the limit of what makes sense with Astrotracer. Discard ratio is pretty high - especially if closer crops are desired, expect about 70% of your shots to be misses with such long focal lengths.

November 2013

 

Actually not much 'Showpiece' in the following images. But still, a demonstration that even very long focal lengths and Astrotracer

may work together, when exposure times are not too long and when conditions and calibration are just right. Faint nebulosity is out

of the question with a slow 700mm  f/11 system but bright nebulae and stars fainter than 10th magnitude may yet be catured

December  2013

 

One of the poorest months that I can recall with eternal rain and/or overcast skies. I only had two reasonably good nights (far from perfect).

Still, theere was a chance to win a few small victories, such as capturing the elusive Horsehead Nebula and the larger extent of the delicate relexion nebulae

in the Pleiades for the first time. Not spectacular images, but for me, "my own, very first".

 

And then some revisits to known grounds. There is always room for experiments and improvements.
