1st light Solarmax 90

Hello guys,

I finally was able to try out the Coronado 90mm filter

My imaging and processing abilities leave something to be desired, but I wanted to share the 1st almost decent result of the batch of movies I took yesterday.
This image was processed in Iris which has some very interesting features dedicated to solar image processing.
Tomorrow Paolo will come to visit and show me how it's really done 8)

Needless to say, comments and tips are welcome: it is my 1st attempt at solar imaging

Data:

Takahashi 102 with Solarmax 90mm @ F20
AP1200 GTO
Lumenera LU075 at 41 fps (ROI)
1000/1500 stacked and processed in Iris.


PS I was also experimenting for the 1st time the brand new feature of Streampix, i.e. the FIT export (works only if you use Iris though ).

Hi Luca,

Exceptional! image, I'm not experienced with solar processing but the processing looks good to me.

Thanks,

Hi Luca -

Congratulations on your new filter. The 90mm is fantastic for observing and for imaging.
The sun has its own set of challenges - the choromosphere has very detailed features to record but they change rapidly. And it is especially hard to find moments of steady seeing during the day.

Sometimes it can work better to hand select a single or a small handful of the sharpest frames to average rather than to stack a large number of frames. A high resolution B&W camera works very well for the narrow H-Alpha bandwidth. There are many different ways to process and present H-Alpha images - Paul Hyndman and Greg Peipol both have very nice processing discussions on their websites.

I'm sure that very shortly you will be posting spectacular solar images for us to enjoy!

best -
Alan
