Well I had a fairly productive night under the stars despite the almost full moon!

Started out learning some new techniques for my DSO imaging, drift alignment with Metaguide etc... and gathering data on M57 until the unscheduled clouds rolled in for a laughs!!!

Went to bed and set the alarm for 03:00 this morning when Jupiter would be in position for an image run... Got straight into it with the ExtQ, then I decided to try to see if I could increase the amplification of the ExtQ by adding a short extension tube and guess what it worked... This morning I calculate that I had about 1.9x instead of the 1.6 times magnification and you can clearly see the diference in the image set attached below.

All image runs were 2000 frame @ 30 frame / sec using Firecapture and the DMK21 USB camera.

Also, I now have a Celestron Ultima 2x barlow on its way to me from the UK, so when I return from my business trip, weather gods permitting I can push the Mewlon harder.

I hope yo like the set, everything has been processed in the normal manner. However, I'm going to have a play with A2!S this afternoon to see if I can make any improvement. Your tips / suggestions are welcome?

PS it great imaging the planets, I can post the result the next day, with DSO I have to wait sometimes a month to complete the image!!!

Been having a play with AS2! (AutoStakkert2) this afternoon and have produced the above image.

It's good, but I think its a little softer than the images that have been processed the normal way with Registax 6. Still, perhaps I'm not adjusting the right parameters yet!

I'm interested to know what stack sizes you are all working with? I'm collecting 2000 frames for processing which is approx. 600MB. The detail is increasing but so is the noise!

So when the 2.2x Celestron barlow goes in I'm worried that the noise will become too much?

Nice scale on that last image was that 1.5x drizzle?

To be brutally honest you need a lot more frames. At that focal length you can easily take 4 min avis without any noticeable rotation blur so at 30fps thats over 7000 frames of which you could be stacking at least 2000-3000 then you wont have any noise issues.

That what I appreciate, its the only way to improve, right... Now I'm just worried my Laptops going to have a heart attack... 2000 frames = 600MB so 7000 must be getting on for 2.5GB???

How much data would you capture in a night? Because at that rate I'm going to need an external harddrive!!!

(Sorry - yes it was with the 1.5x drizzle turn on)

      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
