First Light For Jupiter Test Images Take 2! C9.25 4th April

[asimov (John)]

This is the first time I've seen the stars since I got my new scope, & 10 mins after I shot these it had clouded over & was raining. (crazy weather!)

Anyhow I'm pleased I got SOMETHING! (even if they are crappy)

Seeing conditions were very poor 3-4/10 but I was itching to get jupiter so I ignored that bit, lol.

The first one is with the 2X barlow & IR/UV cut filter. 100 frames stacked. No resampling in registax. 1/50th sec @ 5 FPS.

The second one I added the extension tube just to show the difference between using one & not. IR/UV cut & again, no resampling. 200 frames stacked. Shot at 1/25th sec @ 10 FPS.

Both with: 45% brightness 60% gain 65% gamma.

I left collimation alone, didn't even look to find out if it was out or not.
But I did run the cooler for 2.5 hrs before shooting. Bring on some decent seeing!!!!!


C9.25 & toucam.

gotta be excited, i am!!!!

wrapped also that the extension tube gives the extra scale.

can you do me a favour and post a screen shot of registax at the alignment stage, so i can see how big jupiter is on your video, ie what pecentage of 480 px high?

yes, bring on great seeing

[Astroman (Andrew Wall)]

Awesome shots Asi, cant wait for more.

[asimov (John)]

Yes, I can do that for ya Dave. Just stacking another one now So I'll see if I can upload it before going to work.

[asimov (John)]

Here you are. Hope these are sufficient size etc etc.

I reckon I can up the anti a bit here by extending the extension tube! A project for the weekend on the lathe at work. Great idea re the peltier on the cooler too!

Thanks.

Heres what my image scale looks like on the 640x480 screen for 1600x. With Dennis and his 4x, mike with a powermate and an extension and your extra extension, we will have a great image scale group for opposition.

I wish.....it is our very own Mr Robert T who has the x4 Powermate...half his luck.

Cheers

Impoverished x2.5 Powermate owner

thats what i meant, i was going thru the guys and was thinking robert, but thinking dennis in that he didn't have the extra scale and that even an extension tube with the 2.5 powermate won't get it up to 4x............

apologies to all people living or dead that may have been insulted by a convict riddled tasmanian

[Robert_T]

my 4x powermate is very relieved to be back in my possession!!!

Asi, you must be pleased, I can sense the greatness there just wanting to burst out from the shackles of crap seeing

DP that is an insane image scale you got there, you using an didgeridoo or something for an extension tube or what?

cheers

5x powermate and 100mm extension for the full 7.7x the powermate can put out.

it is fun keeping it on screen during avi capture!!!!

[asimov (John)]

No thanks! Having enough trouble with 2X with extension tube let alone a Dave-eridoo image scale!

[ving (David)]

looks sooo promising!
good image there
