Heya,

 

Interesting to see three plages after such a stark period of inactivity. There's two Cycle 25 polarity regions and a Cycle 24 polarity region that came around the limb just the other day. The new Cycle 25 region, perhaps soon to be called AR2756 has visible umbra with light bridges, but is already decaying fast and will of course rotate out of view even sooner. Still, plenty to see in HA of course! I had to image in the early afternoon due to clouds, so I was imaging from around noon to 1pm which is typically really bad seeing conditions for me, however today it was not as bad and I was able to get some ok data despite the conditions. Seeing managed to get to around 1.4 arc-seconds a few times. I've provided my SSM graph to show seeing fluctuation, what's interesting is the fluctuation to better seeing conditions almost seemed to have a small spiked pattern today, in that there were moments of good seeing every 7~8 minutes oddly. Full disc is a mosaic.

Love the earth scale next to the prominence, of course all are very nice.

Hey Marty,

How does the SSM software work? It is hooked up to a guide camera/scope or something running in parallel with your imaging camera?

Is that new? I don't recall you posting those screenshots previously.

 

I would like to try it out as I general only view/image during the worst parts of the day and I am curious how good or bad my seeing actually is.

Hi Dave,

 

You can make one for next to nothing if you're electronically savvy. I'm not, so I bought a used Airy Labs SSM. I've wanted one for a long time, but didn't want to pay the new price imported. I finally got one used from someone local and that was the only way I was willing to do it. They're not new, they've been around quite a while.

 

Airy Labs SSM:

https://airylab.com/...lation-monitor/

 

Here's what it is, basically at heart, and a DIY paper on how to make one yourself:

https://www.ecu.edu/...face-final2.pdf

 

It uses a little IR photodiode to sample twice per second. I mount the diode with my imaging scope facing the sun. With this we can measure seeing conditions in arc-seconds real time. The unit gives you both the sampled seeing condition real time and the 1 minute average so you can gauge things. The data can be used several ways. You can just use it without any software and just read it from the box (see my image, there's no display because the refresh rate of the LCD wasn't sync with my camera shutter so it shows dark instead of all 3 lines of data), or you can use the data via USB to a laptop and use several pieces of software to do something with the data. There's standalone software simply to view the data an graph it (like my screen shots I'm posting recently). Or you can directly input into FireCapture with its unique plugin (which works great!). With the FireCapture plugin you can program it to initiate imaging captures based on the seeing values with lots of parameters and how long to go. It allows imaging automation based on good seeing. Or you can use it to simply avoid imaging when seeing is bad too.

 

My seeing was around 1.4 arc-seconds at its best today, mid-afternoon, which is ok, but poor for my image scale, but lucky imaging still works out.I really need to be between 0.5~1 arc-seconds for my image scale, but that is truly excellent seeing. Still, it happens for moments between the poorer seeing. If I'm between 1~2 arc-seconds seeing, I can image at these scales though. Beyond that, and really, it's too poor of seeing and I need to reduce aperture & scale. While I can see this real time just looking at the laptop camera feed, it's nice to put a metric to it and to have automation if you want to do something else while waiting for the seeing to improve.

 

It's new to me, but it has been around for quite a while now.

 

I like to use it to measure seeing conditions so I can relate the arc-seconds seeing values to the data and its image scale as it relates to lucky imaging.

looks like the new cycle is up and running.

Indeed, we have had a few cycle 25 polarity regions now in such a short time period, very promising, if not just a fluke. Still, there's a mix of cycle 24 and 25 so we're not out of the woods yet. But I think it's very likely we are at least past the true peak of the minimum between the two cycles!

 

Very best,

This overlap of both cycles can clearly be seen on the butterfly diagrams for all previous cycles, and progression from mid to near equatorial regions is well demonstrated in your full disk images by the two cycle groups.

Great stuff, Marty! Can the Airy Labs SSM data be integrated with SharpCap or only with FireCapture?

 

By the way, how do you manage to upload so many large size images since there is a 500 KB limit. It seems like they are in a single post. Do you change the sizes of each so that the total doesn't exceed 500KB?

FireCapture has a plugin that can use a DIY or Airy Labs SSM data input. SharpCap at this time does not have this integration. There is also stand alone software that you can use that is neither of these that will use the SSM input (Genika Astro). I like FireCapture for my purposes.

 

I host my images on several of my clouds, including Flickr and Astrobin. I embed images from Flickr here to avoid the severe limitations of this forum.

I've been experimenting more lately with trying to pull off mosaics at smaller image scales. So far, 52mm has been successful repeatedly. I'm going to stretch my luck and test 80mm soon. They're hard due to variable seeing conditions and requires a lot of panels, those above were 6 panels (600mm focal length, ASI290MM with 2.9um pixels camera).

 

Very best,
