AR2849 continues across the sun.

the vertical dark line is about 100,000 miles long. for scale the diameter of the earth is about 8,000 miles the filament is about 12 times the diameter of the earth!
Taken is my Lunt ED102, Quark Chromosphere, ZWO ASI174mm-cool camera

I haven't seen the sky in so long with all this cloudy raining nastiness here in Florida. Just awful so far this storm season. Expected though. Sigh. Anyhow, got a break mid-afternoon with some momentarily clear sky. Seeing mid-day is awful in my area so I used my smaller aperture setup and went for a moderate resolution full disc.

This is from a Lunt 60mm modular (60mm F7) HA scope. Single stack. Camera is an IMX253 sensor (3.45um pixels at 1.1" size). Critically samples at F14 so I used a 2x telenegative amplifier.

Results:

These are 2600x2600 pixel size images, much larger than these thumbnails if you care to inspect the kind of resolution that can be obtained from a mere 60mm aperture.

It was supposed to be clear today, but it was 90% cloud cover and the 10% left was a thick haze. These shots are through the haze. The color one is the set up I have always done which is with a diagonal, the B&W was shot without the diagonal, straight through imaging.
Lunt 102ED Quark Chromosphere at the 3 o'clock position and a ZWO ASI174mm (not cooled), proms 500 frames 100 stacked, surface 500 frames 100 stacked

I know next to nothing about telescopes. I am assuming the "camera" is the read section at the very end where we see the "plug in" device?

The other end of the cable then is hooked up to your laptop where you save the images you have taken?

the small red camera has the blue cable plugged in to it and then that is plugged into my laptop. The camera is only the sensor. just before the camera is the solar filter (Quark) which is needed to get the images of the sun, it is also powered.

The large prom from a few days ago has moved off the limb and heading across the sun. There is another batch of proms on the limb now.

If something like that was facing us - could it cause any trouble?
