2 hours of Jupiter from 03.02.2016


Recommended Posts

Up again before the lark today, clear skies are at such a premium at the moment. The seeing was good between 3-4:30 but deteriorated after as the images show.

The usual set up C9.25/ASI120mm, 4000 frames stacked 10% in A/S2, RGB's combined in C/S2. I think I have cracked the red look which has spoilt some of my previous Jupiter's this year. An easy fix using the "red" channel in curves. Some decent data to go with the beautiful scene this morning!

As always all comments/observations gratefully appreciated.

Nice images! The seeing was good indeed for most of them. Just like Jupiter appears to me in my refractor on a good night. The colours look fine to me - nothing artificial about them.

Congratulations!

Top draw Pete. Colour balance looks spot on. How did you sort it out?

I used the curves menu in C/S2. I just reduced the red channel slightly, by setting one adjustment point in the middle and dragging the curve down a little. Also keeping an eye on the RGB levels with the "eyedropper" tool.

Very nice Jupiter's Pete. The second one I think is the sharpest processed capture viewing them full sized.

I've had a couple of better nights here with conditions around the same time, but my results are nowhere near as good as yours.

Enjoyed looking at those Pete. Very consistent. I'm not familiar with the kit. How do you carefully manage filter swaps and do you grab 4000 frames per filter? 

I limit the RGB images to 60 seconds per channel. This gives me around 3500-4000 frames depending on conditions effecting exposure etc. ..

The filter wheel is manually adjusted, but I can change filter and select filter color in Firecapture in a couple  of seconds.

Ok. Do you have to resort to de-rotation software particularly on Jupiter or can you get away without it?

No de-rotation. I figure at the native focal length of 2350mm then approx 3 minutes is probably ok. I have tried WINJUPOS, but found it pretty difficult to understand.

      Hi Guys!
      My name is Daniel and I am from Ecuador, I love astronomy and the secrets our universe holds. I love Jupiter, our big brother, so I opened this forum to talk about facts, secrets, theories, etc. About our gas giant!

      Hello All,
      This is a photo accurate representation of how I've seen the conjunction through a Skywatch 14" f4.6 Dobsonian, using the 17mm Ethos eyepiece combined with the 2X Powermate during the observation of the great conjunction of Jupiter and Saturn, and how well both of the planets fit into the eyepiece field of view.
      My location on the east coast of Australia was totally overcast for the last week and this evening I had a small window of opportunity to actually have a glimpse of the rare event, which no doubt, I will not have a another chance of experiencing in my life time.
      This happened about 17 hours after the actual closest point between the planets, and most likely the difference would be so small that it wouldn't be noticeable without direct comparison. 
      This image was composited by first taking a series of shots through the eyepiece using an iPhone, I chose the best frame of the series than superimposed the overexposed planets with images of the planets captured separately with enough transparency as to accurately show how the planet details looked in the eyepiece.
      Observation time was 22 December 2020 @ 09:51 UTC.
      Clear Skies,
      MG

      So I originally planned to go to a good vantage point from the top of Pendle hill, watch out for witches whilst there. It is a local and well known Lancastrian landmark. However my wife is recovering from hospital treatment and so I didn't want to leave her so made do much closer to home.
      A short drive (2 minutes) took me to a place aside the motorway slip road but with a clear-ish view of the setting planets. I was only use 10x30 bins so the view was not particularly well defined but still impressive when considering distances and such. 
      Anyway it is in the bag but would like to do better if at all possible. 
      If the skies are more obliging tomorrow I may venture out with the EEVA set up and grab some data, however the forecast is not so good.
      Cheers
