1st decent Saturn for two years and 1st light for the ADC

Recommended Posts

Saturn along with all the outer planets has been a chore to image all year, due to the low altitude. I had a bit of a eureka moment the other evening though.

At the bottom of the garden is a gap between the nearby conifers and even nearer cherry tree. Its only around 20 degrees width of sky, good for an hour or so of imaging time, but more importantly its right where the Planets transit the Meridian.

So last night I waited up for Saturn to appear in the gap (12:30) and there it was at a lofty 15 degrees, compared to 8 degrees in the other garden window.

1st capture was with my C9.25 and asi290mm using a 642 Proplanet filter.

The next two captures were same scope, but using my OSC asi224mc camera. The 2nd is with a ADC for the 1st time as well.

The ADC image is clearly improved from the 1st. I simply popped the ADC in the Barlow, with the nylon thumb screw level to the horizon and adjusted the 2 knobs until the image on the screen looked better. The red/blue edges top and bottom disappeared very quickly to be honest.

Not great images by any means, but certainly better than any of mine recently.

And definitely a spot to maybe catch the Mars opposition.

I thought that the first colour image was with the ADC, until I spotted the second image! Mine look like your first one, that just shows you the difference it really does make.

Must have a big garden Pete if you only just found that niche! ;) The ADC certainly makes things better either visually or for imaging when lower down in the sky. I use mine quite extensively too.

A nice result Pete. The ADC seems to be the goods. Do you RGB align in AutoStakkert or RegiStax?

I aligned in Registax 6 and processed there as well. Not sure this hot humid weather is helping much to be honest in terms of image quality.

I think the main drawback is the elevation for everyone that far north Pete. I know what it's like when you want to do some planetary. The tides will eventually turn and we'll have the planets low in the sky, something I don't want to think about.

I recently received the Zwo ADC (as the planets are going to be low for a couple of years), but have yet to try it out for imaging with the C9.25. I did have a quick go last night visually with my ST80, for practice adjusting it and I thought it made a big difference. I might try and get out tonight and give it a proper go after seeing your results.

Pete, a great report and example on what a difference the ADC makes. Glad you found that transit sky hole ?. Geof

Its not much of a gap, but at least its in the right area of the sky. Only 15ft from a bungalow at the bottom of the garden, so stealth mode is essential at that time of the morning.

All things considered it is very good... great ... sometimes I can't even get that on a poor night when Saturn is overhead.

The ADC as worked wonders Pete looking at your images. And that proplanet 642 filter image is a real cracker.

Wow, that ADC really made a difference, Pete. Nice images considering the altitude. I like your setup, too! :)

Definitely worth considering an ADC....... Now where's that Birthday Fairy's address?

      I'm currently on my annual leave in Italy and the sky has been clear all day with no air turbulence.
      The telescope is out - of course - and I managed a session before dinner.
      I thought about sharing some photos taken with my phone and a couple of sketches.

      Saturn imaged on 17 August 2019 using a C8 SCT, Skyris 618C at f33.

      Hello All,
      Sharing with you my best images of Jupiter and Saturn for this year.
      I haven't had the luck of a High Pressure system with no wind speed yet, but on the 17th it was as close as I had for planetary this Jupiter/Saturn season.
      Not my best images of the gas giants ever but ok IMO.
      I'm happy to see that the GRS seems to be repairing itself, last time I imaged Jupiter, the border around the GRS looked like it was breaking up so perhaps it'll be around long enough for my kids to see in the eyepiece.
      Captured at f33. Images consist of  the best 15% frames from 13x60sec @ 60fps for Jupiter and 13x120s @ 30fps for Saturn, derotated in WinJupos.
      Clear Skies,
      MG

      Hello Astronomers,
      On the 12th August, between 18:34 and 19:21 we had a occultation of Saturn by the moon.
      Of course I couldn't miss out of such a event so I took the day of work and setup my gear so that I could simultaneously capture the event as well as observe it.
      I had the SCT recording with the 618C while observing it in the dob... literally at high power it looked like a Saturn rise... massive lunar horizon filling the field of view with a big Saturn rising from under it, literally animated and visible slowly moving up... Looked amazing in the eyepiece... 
      Photos or videos don't even come close to how good that looks live in the ep.
      I had my eye on the eyepiece in the 14" Skywatcher during the occultation and recorded the start and finish times as soon as I noticed them:
       
      Occultation Start 18:35.51 AEST
      Reappearance Start: 19:19.37 AEST
      Occultation Finish: 19:21.20 AEST
       
      I stuffed up the first part video, the covering of Saturn because I still had iCap set to capturing a maximum of 5000 frames left from my planetary imaging, so at 25fps I barely got a 3.5 minute video that stopped just before the actual occultation started... yes I was kicking my self... but at least I watched it... I wasn't going to do the same mistake on the re appearance on the other side...
      Sharing with you my photos and the video of the event... video is sped up to 400%.
      Clear Skies.

      Hey all, I cannot believe my luck. I was out on the 31st July practicing imaging Jupiter and Saturn with the my new ADC and ZWO Asi224MC. All of a sudden the ISS started to appear from the South West heading East. I quickly released the clutches on the mount and followed the ISS the best I could with the finder scope. Everything was set in sharp cap for the Jupiter capture, ROI was set to 320 x 240, 2x barlow plus ADC.  I could not believe it out of 6500 frames I manged to find 13 frames, which I stacked. Second bit of luck, PIPP said it could not find an object, so I turned the option off and it ran without errors. The hero was AutoStakkert which sorted the frames to the front of the ser file. 
      Composite of 3 images from my night:
