  1. This is 100 stack from AVI today.  So stupid today, I use WL filter to solar system align AVX on sun.  Then remove eye piece / WL filter - insert quark.  Was rushing along forgot to secure WL filter to end of refractor.  Left eye to eye piece focused on sun @ 1000mm - hand on controller centering sun.  All sudden the sun turns into brightest blast of light ever seen and hear a thud on deck.  Jump back realizing what happened checking my vision.  Yep wind blew WL filter right off refractor.  Eye still intact, no spots, no vision issue at all.  Had placed IR cut filter in front of diagonal few minutes earlier, must of been enough to shield me for split second.  IR filter and diagonal are permanently staying in 102.  Light blast was brilliantly bright, do not recommend...

  2. Kinda looked like shark on sun today.  First time using second etalon on pst, don't know how 3 dials work together but view and details are much better than one etalon.  Had 30 minutes of sun, was quick grab and go.  ASI 174mm, ten 30 sec vids for a frankenmosaic.

    +1 for the Baader cool Herschel wedge.

    I have the CoolWedge and love it. I know some say the Lacerta is as good but cheaper, but I have to say that in a top quality frac under good conditions the Baader is cracking. I've not done a side by side though so who knows! Worth checking you've got enough inwards focus for the 2", I think that can sometimes be a problem but it's not something I've come across.

    + 3 for Baader nice accessories and filters with it.  The twist lock that came with screws into back of my sct makes for solid camera platform quick swaps.

  4. Haven't seen prom with eyes in awhile.  Didn't see anything until remembered where sweet spot was played with tuner.  Prom at 10 o'clock position with smaller one at 9.  Viewed pst, 2.5 pm, 40mm plossl. My view via paint.  Not sure paint qualifies in sketching section if not can bump this elsewhere :).  Was nice to see some activity.

    So at a very modest 25 fps, an 8 second video of 8 bit data will yield a stack equivalent to a 12.6 bit image. Stacking more will reduce the overall noise further but it can be seen that the quantization error caused by 8 bits quickly becomes insignificant as soon as a relatively small number of images are stacked (as long as the images contain some noise initially).

    Good stuff, I tested again with stacks of 600.  Error was applying similar sharpening to different stacks.  Only difference is using 2 to 3 times wavelets on 12 bit stack to get similar detail of 8 bit stack.  That's probably differences in seeing/wind of captures?  I did another test using pipp to sort image quality before as3 vs just using as3 to sort image quality.  There was no difference in final images at least with this Jupiter avi.
