Good lord it's hot!  Posting this at 5:45 EDT and it is 97F with a heat index of 107F!  I don't think etalons, cameras and laptops love these temps I'm subjecting them to in the morning.  I played around with a few things this morning.  First off, for fun, I spent some of my kids inheritance and added an Antlia 3nm CaK filter to my imaging train with the Lunt CaK BF1200 and the Orion ED80T masked to 40mm just to see what it might add.  Not much but it did make it just a bit easier to grab some proms so did a short animation.  I have the same issue that Brian (on Solar Chat) discussed about a ghost image with the Lunt CaK when you really expose for proms.  In an image below you can see the the Antlia does reduce the brightness of the ghost, but it looks like playing with the tilt of the filters in the Lunt may be the only answer to solving that ghost.  The rest of the time I took some Ha animations, the most interesting being an unidentified active area that was spewing some plasma on the NE limb.  But the main attraction this week is the number of wonderful filaments all over the disk!  Just not enough time to spend getting animations of any of those!  So in no particular order:

 

Full Disk in Ha

 

Full Disk in CaK with Lunt and Antlia Filter

 

Full Disk in CaK with Lunt and Antlia Filter to pull proms out

 

Overexposed with Antlia filter on the left and w/o the extra filter on the right to show the proms do peek out just a bit more

 

Animation of proms on the NW limb in CaK 12:16 - 12:41 UTC, rotated for viewing

Animation of NE Limb and activity 13:01 - 14:33 UTC

And a brief animation, due to clouds, of AR4117 with a little ribbon flaring going on 14:37 - 14:51 UTC

The Antlia Filter has the coolest, magnetic case!

Took me a second to realize you were using your Lunt CaK diagonal and you added the Antlia 393nm 3nmm filter to the mix. 

 

Nice shots!

Great captures, Warren!  And yes, the rest of us are dealing with the Sun's wrath as well.  Thanks for posting!

That little flare animation I saw today close to the limb.  Beautiful animations.

Great discs as usual and good to see from your images that those proms are still there. 

The little flare animation is very nice. You must really be packing the memory storage space with all of these long videos.

 

Although the Antlia magnetic lids are impressive when kept on a nice flat surface, when I are moving them around, I often much prefer a box where a light lid locks down rather than a heavy lid loosely held against any jolting.

Thanks Gary!  I probably could have been a bit clearer talking about the arrangement of the filters!

Thanks Mike!  Yeah, it’s hot everywhere!

Thanks Foc!  I actually keep that box inside the box it came in because I was thinking the same thing!  Luckily my laptop has a 2 TB hard drive and since I limit my captures to 500 frames and always a smaller ROI, I have not run into a storage problem…yet!
