07/29/2018 - Seeing was very good this morning

Submitted by thenakedastronomer

Seeing was very good this morning ... and to think that I almost didn't set up the scope. I got a lot of video to process later but don't have the time today. I did do a rather quick processing job here just to make sure I got some good data. 

I'll post more once I have time to review and process the data acquisition.

Enjoy. Its in the 90's today. And you can blame this thing here... :)

Solar disk - 07/21/2018

Submitted by thenakedastronomer

Trying out some new equipment today ... using a ZWO ASI183 cam with the 90mm Coronado SolarMax II on an Atlas EQ-G mount.  So far, so good ... except for all the darn clouds that popped up as soon as I started my imaging session ...

Here is a image of the full solar disk that I got this morning. As you can see, there's not much going on. In fact, there have been no sunspots for three weeks! That's rare .... and frustrating to solar observers. There is some action on the sun's surface, though ... primarily some active filaments, so it's not a total lost cause.

Solar activity - July 8, 2018

The day started out clear but high clouds quickly moved into the Pacific Northwest skies, so I couldn't do much. Here's a photo I got of some limb activity on the sun today. I have blacked out the brilliant surface to make it easier to see. I was going to photograph surface detail and add it to this image, but the clouds moved in too quickly.  All in all, a fun two hours of observing but I had to end it prematurely.

Come on summer ... where the heck are you? Oh, yeah. It's on the OTHER side of the country ...

Solar Composite (most of it!)

Submitted by thenakedastronomer

As you can see in the photo below, the sun is BORING right now ... absolutely nothing going on.

So I decided to spend a few hours and do a composite of the entire disk. This is a combination of 30 images ... processed with Autostakkert and Registax ... but ... wait ... I missed a piece of it!

Well, I guess this just means I have to try again. Darn. Twist my arm, why don't you... ;)

Anyway, enjoy. This is what keeps you warm. Keeps you alive.

This is a 1 hr & 10 min vid from yesterday. Seeing was poor and the wind didn't help. Taken with a Solarmax II 90 from my back yard in Gig Harbor WA. It was a rushed video so I think I can do better. Enjoy!


Coronal Hole

Submitted by jimwcoleman

There currently is a coronal hole on the face of the sun.  This is a cooler, less dense area on the Sun's surface and it's easy to see as it's pointed at the Earth right now. We are near the solar minimum so there's not much to see on the surface of the sun right now, but I did get this image today, using a Coronado SolarMax 90 and a ZWO cam ...
