My first image of Jupiter

[Carole]

Taken tonight around midnight. Lots of problems getting anything on the chip at all, a common problem I have encountered, but think I've finally cracked what the problem has been all along.  When I flip the mirror over from lens to rear port, I've now realised it doesn't always click all the way and therefore it was looking at nothing when I thought it was dark sky and image not on the chip. It doesn't help when the webcam is not sensitive enough to pick out the stars, otherwise I might have sussed this a long time ago. 

Even managed to get Jupiter on the barlow this time, but could not focus it at all.  I have not posted that image as it's very fuzzy.

STILL it's all progress and learning.

I also even managed to remember some of what my settings were (I think!)
168 of 222 frames@ 15fps
(I think it was the following: min shutter speed,3/4 brightness, 1/4 gain)

Stacked in Registax, could not seem to get much improvement with wavelets or PS, would welcome some help with that.

Well done Carole, that's excellent work!  It's a good clear image. 

Posted at 2:30am - you're getting as bad as me!

Yes Mark, I was thinking exactly the same thing at 2.30 in the morning.  But I was determined to finish the job before I went to bed.  I feel wrecked this morning and have to go to work!!!

fantastic 1st go! Getting the exposure set right is usually the downfall and you appear to have got that just about spot on.

What I would say though is, use 5fps. The USB bandwidth from the camera isn't big enough to carry 15fps without compression, at 15fps the camera is throwing away detail before it even gets to the PC. But that does mean that you have to wait longer to get a good number of frames.

Carole, I am very happy for you, a great image. Join the rest of the worn out, I feel awful as well, this morning!!!!!!


Got my image processing at the moment, don't know how it will be as I had a few problems...................what's new!

Nice one Carole. Again, far better than my first attempt at Jupiter. Keep up the good work. We don't have any really active planetery imagers in the club at the moment (though i'm trying to convince Colin to take it up) as most people do the wide field stuff so it's nice to see some pics of Jupiter.

Who's Colin, Mike?

Excellent image Carole, Jupiter's so low at the moment I can't even see it behind the trees.

thanks for that information Ian, that's the sort of stuff I wouldn't have a clue about.  So it looks like I need to take a longer video but only 5fps.

It was a bit of a juggling act, I set everything up before it rose, and then try to image between trees.

I still have the original AVIs so hoping some-one will see if I can process better, plus the one I did with the barlow.

Carole,

Great image, and by the looks of it lately you are becoming nocturnal than the local badgers. I'm in agreement with Ian, that 5 fps or even 10 fps tend to give you more info when processing in registax, but the object you are imaging on the laptop is also brighter when viewing at these frame settings, and so I find it makes it easier to get the image back into the FOV, if you do lose it from the laptop screen for any reason.

Keep up the good work.

Well done Carol,  I am really impressed with your image.  You have more dedication than I have staying up until 2.30 in the morning! 

[Carole]

I was following the example of some of my peers.  I also decided that if you really want to do this you have to get up in the early hours sometimes.  I had to do that when I was doing my Moon phases project for the GCSE otherwise I never got the waning gibbous and waning crescent phases. 

I want to image the other side of the moon but not when it is a full moon as I want shadows, so I can see another early hours session coming up at some point.

Roll on retirement.

i can always give you an early morning alarm call at 03:30 if you want,
im still working at that time.

[Carole]

Thanks Mac I'll let you know if I need you.

Fancy working all night, I did that years ago and it didn't do my health much good.  So when do you fit in your Astronomy?
