I attach result of Jupiter image stacking

awesome effort ! :smile:

Are you using any editing software to tidy up the stacked image ?
If you have lightroom, GIMP or similar, you would be able to get rid of most of that green hue

Hi Dave and thank you for advise.. I will try it. (green hue is due to camera software adjusting-I use camera Bresser HD) :smile:

OK ... with a little editing you should be able to get rid of that :)

Hi, I send my attempt with GIMP (I supposed that by the help of "magic wand" highlight strips will be possible but it recognize another some colours area :frown:...)
Have nice days (nowadays is terribly hot in Prague till the late night)

looking better :smile:

the usual trick to do simple colour balancing is to do a "white balance" on an image
Hopefully you still have your original image ? and saved edited images with a different filename ?

Never overwrite an original image :smile:

Sunspots/active region of the new solar cycle, cycle #25

Its is high latitude and reverse magnetic polarity
( the active region towards the lower limb)

It's been quite some time since we last saw an active region of the new cycle

Hi Dave , its very interesting...it is mean that sunspot region is in lower part and little left on images?
Today I make observation with solar filter and did not see any sunspots -do you think it could depend as well on earth location? (i.e. Prague versus Sydney for example)? So lot of succes and have nice days

Yes :smile:

No, We all see the same sun

This is a reasonably small region, visible spots are not always there. They were, in that active region, a
couple of days ago. This morning ( Thursday) I notice there is nothing visible

So lot of succes and have nice days
And to you too :smile:

Hi and thanks for answer- it is clear. (although I think taking rigorously while day "sun moving" we see always see litlle diferent part :)) . Do you have some experience with observing sun through H-alpha filter? -I am thinking about it. Hi and have nice day :)

Yes, have been doing Ha solar imaging and observing for a couple of years
See this thread that I have dedicated to that ......

A solar Ha system is quite expensive my system cost
AU$2950 just for the scope/filter system,
I use the same tracking mount as I do for the night time scopes.
My images start at around post #66 on page 3 of that thread.
The images in the first couple of pages are with the mylar style filter for capturing sunspots


cheers

A couple of quick pix of this morning's partial Lunar eclipse, just before sunrise from Sydney, Australia.
The moon was getting low to the western horizon. Trying to photo through a thick layer of atmosphere wasn't exactly conducive to good quality images

Canon 6D, 100-400mm L lens @400mm and x2 teleconverter.

Hi Dave , it is quite interesting, (we can observe it this night as well but from oposite side :smile:). Anyway nowadays is good condition for Saturn observing but late cca 0.30 hod. so I plan to try make some images if will be clear. Hi
