Jupiter 29 April

Lester · #1 30-04-2006, 07:50 PM

Jupiter taken last night at 11pm. Prime Focus of 14" SCT, image was pulsating on screen. Captured at 10 fps. Visually Jupiter looked okay at up to 400x, so I would say seeing was fair but not good. Only processing done in Registax.

nice image scale but I think the atmopsphere robbed you of sharp details. Thats a real pity, I am sure all the planetary boys will chime in on this comment!

Nice one Lester! How lond did you capture for?

To get it sharper you could scale it down in size.

Lester · #4 30-04-2006, 08:43 PM

G'day Houghy and Asi, been trying to process in picture publisher, will try and post another picture, don't know if its any better or not.

Asi I captured for 120 seconds.

Yes, I've been mucking with your originals too. Hope you don't mind. Tell me what you think.I resized it dramatically to try to sharpen it up a bit...

Lester · #6 30-04-2006, 09:17 PM

Asi that is much better, thanks a heap.

When you took yours last night, or early this morning was the image pulsating on the laptop? Cause mine was.

asimov (John) · #7 30-04-2006, 09:35 PM

I was about to mention the difference in our seeing conditions, seeing we live a MASSIVE distance apart....all of 16 K's! Mine was pulsating slightly, but I've seen it worse. I was giving it 8/10 seeing. Mine were taken later than yours though, that could account for it.

Between 1-3 AM seems to be the best at the moment, but theres no set pattern you could set your watch to though..

Lester · #8 30-04-2006, 09:51 PM

See how I go tonight Asi,

Think I will try 60 seconds capture time and 120 to compare sharpness.

asimov (John) · #9 30-04-2006, 09:56 PM

Yes, rotational smear perhaps. I'm not even going to look outside in case I get tempted! I need an early night.......Yeah right....be right back, need to see if the car is locked......he-he!

asimov (John) · #10 30-04-2006, 10:02 PM

Nope! I'm giving it 6-7/10 naked eye out there now. I bet if I got joop on the laptop I would downgrade that to a 4/10. After midnight it may pick up though.

Go get 'em Lester! This is a great learning experience for you with a webcam, Crappy seeing or not..

Lester · #11 30-04-2006, 10:09 PM

6-7/10 Now, when I had 4/10 at 11pm yesterday.

I better go bait up my hooks, er I mean charge up the laptop.

asimov (John) · #12 30-04-2006, 10:27 PM

Good luck. I expect to see a Lester-hubble-image here by lunch time tomorrow!

Lester · #13 01-05-2006, 12:08 AM

I got Jooped. One AVI then drizzle. Will try and post image by tomorrow evening.

Nice one Lester, I think you were let down by seeing by an otherwise nice job.

In your original post, is the attachment on the right the original size? It's huge? Did you use any barlows?

Lester · #15 01-05-2006, 08:20 AM

Howdy Mike,

Images were only taken at prime focus, no barlow or eyepiece projection.

I have got a barlow on order.

Lester · #16 02-05-2006, 08:37 AM

Another shot at processing from the same night but with less enlargement.

Comments welcome.

iceman (Mike) · #17 02-05-2006, 08:47 AM

That's a great one! Congrats!

asimov (John) · #18 02-05-2006, 08:51 AM

Good one Lester. Looks nice on my laptop (LCD)

Lester · #19 02-05-2006, 10:14 AM

Thanks Mike and Asi,

I am gradually getting the handle on processing. Have learnt that bigger image is not necessarily better, unless seeing conditions are stable.

asimov (John) · #20 02-05-2006, 10:20 AM

Yes, I'm all for huge image scale to a point, but they look much sharper if one doesn't over step the mark in this area. I have no intentions of using F40 or even F30. F20 to F25 is about right for my scope & my visual likes on Jupiter pictures. This excludes resampling in registax of course..
