Melbourne Sun on 270123 - spectroheliograph

[Maurice]

Hi all

Just recently built myself a spectroheliograph as per Mr C. Buil's Solex recipe & here attached are a few initial attempts in Ha and Hb.

The imaging scope was a SvBony 70mm f/6 refractor

The best 11 Ha scans (rebuilt into a solar disc with the excellent INTI software) of 21 were aligned & stacked in Autotakkert 3! and then wavelet deconvolution sharpened with Astrosurface. Same process for the Hb data, but only 4 scans used here.

I've also attached a crop of a single scan (disc occulted in software) to show the prominence on the top RHS of the frame.

Very compressed versions attached here, slightly better on Flikr here:

Probably worth a zoom in to near full size..

PS sorry - forgot that I had a Ca band image from the same session & now attached.

Maurice,
An excellent first light for your SolEx.
Well done mate!
Look forward to see more results.

Wow Maurice, what great first images!! You seem to have mastered the device straight away.

I'm impressed!

[Maurice]

Thanks very much Ken.
It's been a while.... hope that all is well.
It is a different set of challenges with the spectroheliograph compared to my usual lunar & planetary imaging - but I'm looking forward to it!





Thank you C & P..
Not sure that 'mastered' is the right word here :)
I have been lunar & planetary imaging for a while (about 30 years), but this is different in a good way.
We'll see how it goes.





Cheers Mirko :thumbsup:

Maurice,
Yeah still settling in the the "downsizing" at Junortoun.
We finally have the car in the garage, and most of the boxes at least emptied.
"I used to have one of those" - "It must be somewhere" become daily chants.
Haven't managed to get telescope, spectroscopes or SHG's set up yet, but I hope it won't be too far.
Ken

Wow...you've moved - again....

I hope that you get to play with astro toys soon.

Cheers
