Registax not performing

Recommended Posts

Early this morning (1 May) I imaged Jupiter, Saturn & Mars with my C8. (Celestron C8 SE, ASI120MC, ADC).

When I tried processing the image videos, at the 'wavelet' stage in Registax6, Registax would not improve the blurred image at all on the Jupiter and Saturn images.  (0.100 sharpen, 100%) I have had this happen before and put it down to poor seeing and poor raw images. The raw images here looked rather blurry.

However the Mars images, taken under the same conditions, turned out quite well, with a fairly sharp planetary edge and a real-looking dark patch.  Not bad considering the small size (about 10") and the low altitude (about 10 deg) and the indifferent seeing.

Can more experienced imagers suggest the problem with the Jupiter and Saturn imaging? All three planets were imaged within an hour, with a 1000 frame .ser video (converted to .avi with PIPP because Registax did not accept the .ser files) and processed in Registax6.   Initally I focused on a Jupiter moon, and I refocused for Mars on Altair, at which point the focus seemed close.

UPDATE: I tried processing again with different settings, and got the Saturn images up to the standard of my previous efforts.  The Jupiter images improved, but remained poor, showing just the two principal cloud belts (but it was low when imaged).

      Hi there,
      I am relatively new to astronomy, as well as this forum so I'm sorry if anything seems obvious that I don't pick up on. However after using a very basic set up to capture some photos of the moon I wanted to invest in some astrophotography equipment.
      Ideally I am looking to spend around £800 - £900, and I wanted some ideas on good mounts as well as scopes that can be used to take decent images of the moon along with other celestial bodies in the solar system. 
      I have been looking at the Celestron Nexstar 6SE as well as the sky watcher explorer/evostar series attached to a EQ-5 Pro GOTO Mount but as I said I am relatively new to the hobby and have no idea what's good and what's bad. 
      I would also prefer it if the mount is suitable for deep sky astrophotography along with planetary imaging as once I get the hang of planetary imaging I would like to take a stab at deep sky astrophotography.
      Any help would be greatly appreciated.

      Night of 12-13 June. I had not had a go at Saturn and Mars for some time, so set up the C8 to image them.  Kit: Celestron C8 SE SLT, ASI120MC, ADC.  Seeing: initially poor but improving through night.
      The Jupiter images were unexceptional, but the Saturn ones resolve the Cassini division well (compared with my earlier efforts). The rings look odd - I wonder if this is the conjunction brightening I have read about?
      Mars was very low when imaged at around 2am BST. I packed up because I was tired and cloud cover was forecast. I still got some surface detail.

      Got some images of the Europa transit, with C8, ASI120MC, ADC. Processed in Registax6.
      Also two other moons.
       I don't see colour in this image at all, either to the eye or in the histograms. It was recorded as a RAW16 .ser file, which I thought would be colour (and Registax gives it a tick for colour). I wondered if I had goofed somewhere.  So tried turning up the colour saturation (2nd image).

      Hi Guys,
      I know, 130PDS is not the right tool for Planetary AP, - but "you use what you have, don't you?"
      I wonder if someone has managed to get decent or maybe even amazing pics of our neighbour planets with 130PDS?
      Please be free to share you planetary pics below and share your knowledge with others in this field.
      I tried on Jupiter several times with and without barlow and
      the results were very... I mean, VERY bad  I even afraid to show them  
      but till last night,
      As I managed to get something recognizable as a Jupiter  
      at last
      I am still a beginner and my first 2 cents below.
      130PDS, ZWO ASI224MC, 3xBarlow, SharpCap Gain=400

      This morning I set out to get some images of Mars and Saturn, having got a good result with Jupiter a few nights ago. It turned out to be one of those occasions when almost everything seemed to go wrong.   I struggled for ages in the dark to get the 8SE mount attached to the tripod (it has some white stickers on it now), the solar system align turned out to be inaccurate, and the laptop kept crashing.  It became a race to get some result  before daylight intervened.  I aimed at Jupiter, and tried out Sharpcap's exposure histogram before turning to Saturn.  The focus would not come good (as the stacked images confirm) so I switched to Mars, with the result shown below.  The dark smudge appears in all six videos and seems to match the position of Syrtis Major.
      The Mars result looks encouraging, considering that it will be twice this apparent size at opposition. The altitude of Mars was about 10 deg.
      Equipment: C8 SE, ASI120MC, ADC, processed in Registax6
