Pleiades unmodded 600D tips most welcome

Recommended Posts

Hi everyone, was out last night till 2.00 ish brrrrr!!!, my first serious attempt at Pleiades on my un-modded 600D & no filters Canon 55-250mm @ f5.6 (would Baader Blue filter help bring out more detail ? ), fighting against all night dew was a headache but that's why i bought the wife a nice hair dryer for :grin: , final shot is 3 subs @ 1600 / 20 secs, 8 subs @ 1600 / 60 secs, 10 dark frames & 5 flat frames (i keep forgetting to do them), processed in DSS & CS6. My 'main' stars seem blown, i used levels + curves but not sure exactly what to adjust to reduce the bright whites but keep background dark & keep blues in tact ?

I'm please how it's come out & hope you like it too.

Nice job!

Good work with the flats, it really helps the vignetting.

The image is nice, you can definetly see some nebulosity in there. I think you need to do more subs though. And I think you can play around more in DSS to tease out the mid range that should be in there.

Here is a similar shot i did sunday:

2nd DSO M45

It's an unmodded Nikon D5100 on my 6" newt. I had to work quite vigorously with the mid range sliders in DSS then push the saturation up a bit. 33x30sec subs, 9 darks. I think I was very lucky with the result, and the focus, but using zoomed live view to focus is really effective.

So just keep playing with the levels and sliders in DSS and you should probably be able to tease out more data.

Guessing he used his EQ5 and C8.

Erm. Meant CG-5

60 seconds is usually no trouble. I've heard about guys in my club who managed 3 minute unguideds... :o

Sorry, Carl is correct, i piggy-backed the 600 on my C8, i did a couple of 4 minute subs but the neighbour was nice enough to turn their garden light on to let the dog out & the dew was very heavy then so i didnt bother including that in the stack, should still be able to do a lot longer than 4 mins as well, just take the time to set the scope up correctly first, i pay a lot of attention to the mounts level using a bubble.

I did push up the mids & the sat but the whole pic went blue but looking at your pic Carl dosent seem to bad an idea, ill give it a go m8 :-)

      Hi all,
      For a long time I wanted to shoot this frame, probably from the early days of my astrophotography adventure.
      Finally after all these years I managed to get a decent result of the 'stuff' between these two beautiful nebulae. Fairly happy with the image but always looking for improvement.
      I hope one day to redo this all with a mono camera and filters. 
      Apart from NGC1499 , M45 and the Baby Eagle Nebula no idea what else is in the picture. If you happen to have an idea feel free to educate me.
       
      Some info on image and capturing:
      Widefield Pleiades to California.
      Taken over 2 nights with a total of 11hrs 25min integration.  
      With a stock Nikon d610 and Nikkor 85mm 1.8 objective.
      Tracking was done with the Skywatcher Star Adventurer.
      Lights and all calibrations frames were stacked in DSS.
      Processing was done in Adobe Photoshop CC using Adobe Raw, GradientXterminator plugin, HLVG plugin, Nik software plugins and Photokemi action set.

      Another test shot for brand new lens (same night as other tests of the same lens).
      Again, main stars and their colors are not distinct enough.

      Capture: 16 lights x 10s x 1600 ISO, master bias
