The solar show

Posted By Gianluca Valentini

Hello guys

I could not process the larger image because of a parasite luminosity. I hope to get rid of it in other sequences I captured with different exposure times. However here is a detail of the larger part of the prominence where the parasite was not so invasive and I could work on the levels to emphasize all the prominence. this has also been enlarged to 150%.

Ciao

The solar show

Posted By Gianluca Valentini

Still processing the same prominence which is to me one of the best I've ever seen and imaged. These 2 shot are from different sequences with different exposure times. Alas the parasite luminosity is there to stay. I checked with other Coronado users and it seems that it is a common problem with Barlow lenses (even though the Baader FFC is not a proper barlow, they say). This would also explain why the Powermates seem not to create the problem since they are not barlow lenses but some sort of eyepiece projection device. To further confirm this last fact about Powermates, I tried for the first time my solar prism and, while there was no way to bring it to focus with the FFC (3X), all my Powermates (2.5, 4. and 5X) reached focus without problems.

However here is the first picture and the other in the next post.

Ciao guys

Very nice Jim, considering the conditions we have for Juoter here in the north! At least you can see it :C We've been having so much rain lately that it is hard to remember the way the sky at night looks >sad >sad

Ciao Jim

A Big Sun

Posted By Gianluca Valentini

THEN IT'S TRUE WHAT THEY SAY: BIG IS BEAUTIFUL grin grin Nice detailed full disk Alan. When the seeing doesn't cooperate that's about the only thing one can go for sad

It must have taken forever to stitch 16 webcam images Alan.
However, even we had a little truce from rain yesterday, but the seeing was so bad that the image in H-alpha looked liked a white light image, i.e. there were no details whatsoever and you could just see the dark spots of the active areas. I recorded some sequences, but they are definitely trash can material even the F8 ones at only 820mm focal length were so bad to be a waste of time to process >sad

Tomorrow the weather should clear up, but I truly hope that the seeing won't be as bad asit was yesterday otherwise the frustration will be double. Tuesday and wednesday are foreacsted as good days, but, needless to say, I gotta work :C !!!!

Ciao Alan

The views of the sun

Posted By Gianluca Valentini

Very nice composition Tom!

I say this with a little bit of envy since it should have been suny here today and I was ready to go out and eventually see this 875, but the clouds are still here :C and by the look of it they are not going to go away shortly!

Ciao and thanks for posting

Solarmax(?)

Hello James,

there are some solar imagers here! I'm one of them and it is a pleasure to welcome you to the forum. You just bought a great instrument that will give you a lot of satisfaction (I hope).

Let's get down to business: you got all it takes to start. I would begin with the Atik (I don't have one, but I guess you can use it as a good webcam): capture some video and then process them with Registax. After that you will want to get into taking pictures with the fine cameras in your possession.

Have fun grin

880 & 881 in h-alpha and WL

Posted By Gianluca Valentini

....and the WL, but with a touch of colour which, in my opinion, increases the contrast.
