Third Evening with my new mate ZWO

Recommended Posts

Thanks for the previous advice folks...

So moving on from my first two outings with the ZWO i decided to have a go at Jupiter (see attached) Now before you comment I realise that this is a pretty poor image in lots of ways, however, the purpose of showing it, is that hopefully I'll be able to put another side by side in a fews years showing some progress and understanding regarding imaging?

I downloaded several imaging programs yesterday following advice for which I'm grateful. Now some programs look a lot more complicated than others so I ended up using Sharpcam and Registrax3 for my image... I will look at the others when I have more time I promise...

Today, I'm reflecting on yet more new terminology I hear of... I think I get Gain and Exposure, even darks I understand... But wavelets, Align points and load flatfield are new terms that sound like the devils work to me...

I must just reiterate that the purpose of my ZWO purchase was to do live laptop based observation, or Electronically Assisted Astronomy, but I am really keen to use the instrument to part of it's full potential, hence my venture into technically challenging world ?

One thing I did learn of a YouTube clip yesterday was to change the image size before capturing which has resulted in me actually being able to see a finished image which at least can be recognised as Jupiter!

 

Here's an additional Question - Most people recommend Fast scopes for imaging... I see a fair few people use 130, 150 Newts... Skywatcher do a new pds Newt model which they state has the secondary mirror slightly closer to the primary which helps Astrophotography. Why wouldn't (other than cost) would you buy the 200 version? this would be more bang for ya buck yes/No? 

It's a big post, but it's a huge subject........

P.S Where's the Astro imaging school??

Not a bad image at all. If you convert it to jpg, it will show directly in your post. BTW, for planetary imaging, slow scopes are better, and aperture is king, because the surface brightness is much higher on planets, compared to deep sky

Thanks for the jpg tip ? and of course the imagery advice...

I'm going to capture some more video to work on tonight (hopefully?) I also have a tiny list of doubles and a triple to find... 

Question - So I get two options with the capture software (whichever one I use)... Still frames or Video?

Why take stills? Is there any particular advantage to doing so? They are stacked both the same yeah so I will get more frames in video?  Only thing I can think is you can adjust the length of exposure with stills?

      Another attemp on Jupiter from me, a novice on astrophotography, lol. But this time image is taken using Orion Shorty Plus 2X Barlow. Image is still captured using Canon 60D, prime focus on CPC1100. Stacked and processed using Registax and Instagram as usual 🙂
      Two attemps on Jupiter which produce more or less the same image. Seeing from the image, I think this barlow degrade image quality quite significant. Please advise if any. Thanks
      Cheers

      Hello Astronomers,
      After imaging quite a detailed image (for using an 8" SCT) of Jupiter last year, I was hoping to match or exceed it this year, but I can't quite get that atmospheric condition which will allow me to capture those fine structures.
      Attached is my best Jupiter this year... I would have thought I'd get more detail since Jupiter passes overhead near zenith... I guess I just have to keep trying and hope for that super still night.
      Clear Skies,
      MG

      An image of Jupiter taken late evening, 27 June.  Not as good as some other people's efforts, but one of my best Jupiter images this year. The planet was low (around 15 deg) and the seeing was not great. CPC800, ASI224MC, ADC, captured in Sharpcap, processed in Registax6.
      Best 20% of 5000 frames IIRC.  One of the images here is a random raw frame, to show what I had to work with. Io should be visible on left in the processed image.

      An image of Jupiter taken early morning, 16 June.  Not as good as some other people's efforts, but the planet was low (around 15 deg) and the seeing was not great. CPC800, ASI224MC, ADC, captured in Sharpcap, processed in Registax6.
      Best 15% of 7000 frames IIRC.  One of the images here is a random raw frame, to show what I had to work with. Ganymede should be visible on left in the processed image. GRS coming into view on left.

      Just got 2nd hand Celestron CPC1100. Tried to take Saturn and Jupiter image with Canon 60D, prime focus. Took 1.5 minutes (Saturn) and 2 minutes (Jupiter) videos, stacked and processed with Registax and Instagram (lol). Hope to get better image later.
