Sunspots AR 1861 & 1865

Spaceweather tells us that these sunspots "have 'beta-gamma-delta' magnetic fields that harbor energy for X-class solar flares".

Single shot with a 7D and 60 FS-C - silver sheet filter (home made from A4)

Good set up, good acquisition, good processing.
Only with home made filters, watch for precious eyes and then camera's sensor.

Thanks for the kind words I usually stack about 100 frames or so, but single frame exposures seem very decent.

It so happens that 77mm filters perfectly fit on the FS-C, so I stuck on the inside of a polarising filter a cutout from an A4 Baader solar sheet.

Setup looks like this:

Looking at your website, how do you stack your 7D images, do you shoot in video and then what software d you use to stack the images, thanks,

With Baader, you are in good hand.
Keep up the good work.

My image today with 7D and 100-400 mm and thousand oaks glass filter

Nice shot Tony - I like it when you can see two shades of grey in the spots. It usually means focus is spot-on and that turbulence was not-so-brutal. Is this a glass-filter that you use? I only tried these sheets..

I use Registax (Win) or Nebulosity (Mac). Any such software first aligns the frames, then stacks them using a variety of settings (median stack, arithmetic, etc).

The idea is to improve the signal to noise ratio, so you can "pull" on the levels in post-processing without getting too much noise.

I use a thousand oaks glass filter, I use a mac so I need to download nebulosity, doing layers in photoshop is pita Thanks; the thousand oaks was for my Orion ED80, by adding some felt liners, it fits the elsn hood of the 100-400 mm, I also have some baader filter, here was my set uo for the transit of Venus last year:glass on 100-400, baader on 70-200

The Baader sold here is a silver sheet that looks much like regular flower wrap. The darker version (that you seem to have) is what they call here "Mylar". This Mylar gives a nice, orange sun when photographed and they boast "true colour", unlike the silver version that is supposed to show more detail, but with the WB shifted towards red.

Will you tell me how satisfied you are with Nebulosity? I have recently switched to mac and it seems astro software is virtually non-existent.

I tried to stack the sun shots, but found it dificult to align as it was asking for stra alignment, tried using the spots, but did not wor; photoshop layer was easier but not sharp.

BTW E_L; Why is that your images are almost 90 degree counter clock rotated?
Did you take the images with portrait mode of camera when shutter side of camera body was up and forgot to correct the final images?

It's true - forgot to set them straight
