AR2529 10th April 16

Recommended Posts

Here are two images taken today of the AR2529 region. :-) It was a fab day to solar observe. Luckily I was off work all afternoon.

Was a beautiful day (well morning anyway) for solar today . A couple of nice images you have captured there.

There were thin layers of clouds around later in the afternoon. So, I guess it is not the ideal situation for imaging. But hey ho, when you live in Scotland, you take any sunshine you get!!! :-)

He didn't need a lot of imagination to come up with that! ?

Nice catch of the monster AR. What instrument did you use? I do get the impression that it is just outside of the main H-alpha band. Some filamentous structure is showing, but the penumbra is a lot more prominent than what I get when the etalon is exactly on band

Thank you Michael, I'm afraid, that was my very first go at imaging. So far I used the telescope only for visual observing. I've recently bought a ZWO174MM camera, so I was playing around with brightness, exposure and focus etc. I am totally new to imaging and most certainly on how to use registax and Photoshop. 

On the black and white still pictures I took, I can see the filaments much better though.

Very good first effort I would say. I think the biggest improvement you could get is in the tuning of the scope. As a rule of thumb, you can watch the histogram of the image while tuning. On band the image is darker than off band, so the bulge in the histogram moves to left while approaching the optimum, and moves right as you move away. 

Clear skies!

I just quickly plugged in the camera to find the image histogram on Sharpcap. Got it. I will use your instructions next time it is set up! Thanks a million.
