Time Lapse of Sun In H-alpha new
      #5505205 - 11/05/12 10:31 AM Attachment (21 downloads)

The link below opens a time-lapse animation of images covering 65 minutes with a 5-minute interval between frames. I used a 70mm refractor with a 60mm H-alpha filter. The native focal length is 480mm, which was extended to 960mm with a Barlow. The angular size of the Earth at the distance of the Sun is about one-fourth of the length of that prominent horizontal filament just above the center of the image.

The file is 4.0 Mb, so it might take a while to fully load the animation.

Way cool! What I'm really blown away by is the chromosphere layer you captured there on the limb. Is that because you have a DS? Very neat either way!

That's very nice! Amazing transformation on that timescale, imagine the speeds of those features; that would be some windburn

I'm sure it will become obvious when you tell me, but what is a DS?

The scope is a 70mm Pronto with a circa 2001 model Coronado 60mm H-alpha filter. The camera is a DMK 640x480 model.
