Jupiter in bad seeing - 16/06/2005

[iceman]

Hey guys.

My first Jupiter image with the EQ platform, unfortunately it's the boring side of jupiter and was taken in bad seeing (4/10).

My alignment was much better last night, I was able to actually capture several 90 second avi's of Jupiter without touching the telescope or the laptop, once! That's a first for me! :clap:

Anyway i'm not really happy with the image because of the bad seeing, but I thought i'd post it anyway.

Oh and now I need more image scale.. I need a 3x or 4x barlow!

There's nothing wrong with that Mike. Even with poor seeing I find it much smoother and "clearer" if that makes sense. Excellent! How long before you get a 350D. Or better yet the new 20Da. Just imagine all those 30-45 sec shots you can take now. Even longer if your prepared to crop the outer areas. :2thumbs: It's only a tiny step after that and .......shhhhh....eq mount and goto :P :lol:

What do you mean boring side and bad seeing, nothing wrong with that pic Mike, your teasing arnt ya :poke: Looks good to me. :thumbsup:

Just on Paul's "tease" there. If you use the tracking platform, and a DSLR, as he suggests, what length of time before the outer edges start to trail because of field rotation? Registax, or Maxim DL will rectify this.

Eq Mount.... Goto..... Eos20Da...... sounds like the dark side to me ..... Nice results Mike, can't wait to view your images with good seeing.:D

No pleasing some people!

That is a fantastic shot Mike, don't put it down.

Still need a shot of the whole set-up together. (Platform with dob on it)

Who said I was teasing :D The Dark Side will win every time :lol::lol::lol::evil:

Actually it won't take long to get field rotation. For shorter shots say 30 -45 sec you may only have to crop out the outer 1/4 of the image, but for progressively longer shots more and more needs to be cropped. But as gary is suggesting, multiple 30 sec shots stacked and rotated in Registax can work. My first Eta Carina shots were done in Alt/Az mode, rotated in reg and then cropped.

I don't own a DSLR. My digicam can do 30s exposures, i'll be trying that using afocal (steadypix adapter).

For now i'm waiting for a night of good seeing, it's just been total crap the last week. Got some avi's of the double shadow transit last night but again the seeing was crap.

Good shots again Mike. :D A question, can I set the camera to multi-images/video mode, & get reasonable results? L.

[iceman]

If you mean "burst" mode, where it takes 5 quick pics in a row, then yes, that's what I used to do when I did afocal stuff.

Oh and I figured out why the seeing has been so crap the last week - the jetstream has been overhead so it's been playing havoc. Hopefully it will go away, when these clouds do.

Very nice image Mike. Lots of data and lots of detail in there in spite of the poor seeing and steep learning curve.

Cheers
