Saturdays Ha and more on the SSM Plugin - 28th July

Post by marktownley »

I'm starting to like this plugin more and more. I spent some time yesterday with it in Sodium with the Hat, and while the seeing was not up to much it gave me time to get my head around how it works, this morning I was keen to give it a go weather permitting. I was lucky to grab a gap first thing between rain bands.

The plugin was able to pull all the best frames which was triggered by the Airylab SSM, it's rare I get a quality graph like this in AS3

The dip was a bit of cloud that drifted by... I started off using my pair of double stacked Lunt 50s on the ED60 scope to get the full disk. Coronado BF15 and PGR Chameleon 3 camera was used.

Then I took off the double stacking etalon and replaced at the other end with my Daystar Quark to get in a little closer on the departing filaments. I should have changed the camera as the image is over sampled with the 3.45um pixels of the CH3, the 5.86um pixels of my IMX249 chipped PGR would have been better.

May get some more gaps between the showers in a bit!

Based on the quality graph, Mark, it looks like a winner. I'll have to take a look at that option myself.

Nice images. Once those filaments have gone there won't be much to see at these scales.

No chance of anything this weekend here in the NW......cloudy and rain showers.

Thanks Stu. I got another gap so had a go at some Calcium. Just going through the data now.

And some CaK using the ED80, Beloptik Tri-band ERF and homebrew CaK filter. The seeing was all over the place now and it was a case of shooting in the gaps in the fast moving clouds, but the software seems to have pulled some respectful data from it. Gradually zooming in at different levels here:

Quite pleased with these as the atmosphere was very unstable. Rain forecast now for the rest of the weekend so unlikely imaging till early next week now. Will give me some time to work on a reliable way to get the PGR cams to export the data at the native rate of its analogue digital converter; i've been having some success with this just need to work on my method to get it reliable and repeatable...

Hi Mark,

that is an exceptional quality graph you have there. Seldom seen anything like that. How did you configure the plugin. I suppose you have set the discard treshold and recorded several bursts in one capture file? (If not you had exceptional extremely stable seeing ...)

Hi Mark...

Excellent results in bot CaK and Ha using the plugin.

Thanks Everyone.

Here's a screenshot of the SSM display from friday:

Imagessm by Mark Townley, on Flickr

It tells a story, it was cloudy until about 10.20am -the yellow line is the suns intensity, you can just about make out when the sun was out the line was wiggly which is the tell tale sign of high cloud / haze interfering with the view. The seeing was really up and down, very unstable, and was getting worse till I finally decided to call it a day just after 11am. The 2 horizontal lines are the trigger and cut off lines - in this case when the seeing was 3" it would start the camera recording, and when the seeing was less than 3.8" it no longer records. The idea is to set the trigger and threshold so that you are only capturing the data in the bottom of the valley troughs on the graph. I got some images around 8am with the 203mm HaT and Na quark, the seeing was slightly better then, but even this method can't work miracles when the seeing isn't up to it.

Soft and mushy!

I'll try and get some more screen grabs of the software in action in the days ahead if the weather plays ball!

Interesting stuff Mark.

I may get my SSM out again and see if I can get it to work.

For higher resolution stuff I think it has real potential Steve.

Looking good Mark

I had a few problems with the plugin in Firecapture 2.5. It worked OK in version 26 though

It is a great plugin. I will use from now on for HR imaging (WL and H-alpha)

Thanks for sharing

My autostakkert graphs look like the one you got most of the times ;-)

You got some cracking shots Mark, I like the sodium the best :bow :bow :bow

Amazing how we had a 30 degree week and the moment Friday evening came it started to rain and we had a rubbish weekend. Oh and look out the window Monday morning and it is calm and blue sky sunny again :evil:
