Saturn storms + Transit & shadow transit of Rhea

[Clayton]

You are a real inspiration to me Trevor, and I'm certain many others as well. Congratulations on your achievement

This really is amazing,not only fine images,but real reserch data that is then used by professional astronomers for their studies,this type of result,must be a wonderfull feeling for Trevor.

Just wondering if its possible to briefly explain how you measure the storm position accurately.

thank you for sharing.Chris

Cheers

Always happy to help if I can Duncan, I enjoy my astronomy very much and I think it is great to see others start out on the imaging path, it can be incredibly rewarding.

Thanks very much for your most kind remarks Clayton, we may have a small population but we have many amateur astronomers that do amazing things in quite different fields of astronomy that contribute to astronomy as a whole.

Thanks very much Chris, I do get quite a buzz out of it, especially considering just how isolated from the mainstream it is out here in Broken Hill.

Regards the measurement of positional data, to accurately measure the positions of various features on the planets you need to open WinJUPOS, from the PROGRAMS menu select CELESTIAL BODY then select the particular planet from the list. From the RECORDING menu select IMAGE MEASUREMENT click on OPEN IMAGE and load the image you want to measure, accurately fill in the date and UTC.

Go to the ADJUST tab and size and orientate the outline to suit, I always do this with the orientation of Sth up and West to the right. Be very accurate with the outline adjustment. Go to the Position tab and you will have a cross hair that will move to any position you indicate on your image. As you move the hover arrow around the image you will see lat and lon changing in the positional boxes above the image, when you have the arrow head on the detail you want the positional data for right click and the coordinates will appear in the positional boxes to the left of your image.

There is a tutorial done by a Japanese observer on the net that helps a lot regarding how to manipulate the outline for the planet.

Ah-thats how you do it!,thank you for explaining that,you explained it in

such away that it was understanable,i was not at all familar with that program,sounds like a handy tool for what you do.

well done!it really is a pleasure to view your work,I like the web site too,

suprised not many have subscribed to it.

cheers Chris

Excellent images Trevour. Im aware of the amount of processing time thats gone into something like this and it shows great perserverance and skill. Makes me want to get back into the planetary imaging again.
Dont normally have time to surf around but had to comment on this.

Well done Trev. Your missus is gonna kill you with all this fanaticism. As for the images I really like the look of the transit and storm shot. A lovely set of images.

Thanks for taking the time to check out my website Chris and hope my explanation of how I measure my images made sense.

Thanks Paul, your not going to believe it, but I didn't image the storm when I should have in the early hours of Sunday March 14th. I was playing in our local Lawn Bowls association champ of champs and thought I might have struggled if I was imaging through to 3:30 that morning.
Mind you, it was hard to give up the opportunity to have another crack at imaging the storm. At least the wife only has to put up with my early morning imaging sessions every 4 nights now, weather permitting. Still, no matter how quite I try to be when I bring my laptop back inside, usually by 4 am after I have packed everything away down in the observatory, I always seem to manage to wake her up. But Like I keep telling her, its all in the cause of science.
