Exploring the Sun: Amateur Solar Imaging Techniques

In summary, Dave has been posting photos of the sun taken with his camera. There are two large spot groups visible across the disk and new spots are appearing east of the long string of spots. The activity is continuing to grow in complexity and size.

A catch up of some latest solar activity
All images with a Canon 6D, 800mm ( 400 + 2x teleconverter)
and a Thousand Oaks white light filter

The spot group to the right on the disc has been producing a few large M class flares
over the 1st and 2nd of Oct. - M5.8 and M8.3 and the largest one, today, at X1.0

I don't do too much image editing, mostly some sharpening. I find that imaging through a camera
lens and teleconverter doesn't produce the sharpest of images. there is just so much glass in the
optical path.
If these were images through my telescope with no lenses in the optical path, there would be such
a huge difference.

I should have commented on earlier posts. I have always orientated the images to show the correct
orientation as displayed by professional sites ... NASA etc.
In that light, east is on the left side of the disk and north is to the top. The spots are rotating from east (left) to right.

Comparing this new image to the last one in the previous set of 3 images post. You can see a new
large region rotating into view around the east limb of the Sun. It was only just becoming visible
for the image on the 1st Oct. . It will be interesting to see if it starts unleashing flares in our direction.

As usual, images have been correctly reorientated East is on left, North to the top
(Sunspots appear on the East limb and traverse the solar disk to the right)
The motion of the spot groups can be easily followed across the disk

The Sun in Ha 13 Apr 2018

Been off work all week with a not nice case of bronchitis, am feeling very unwell :frown:
but did decide to haul the gear out today and do some solar imaging
Reasonably quiet, 4 or 5 small filaments across lower part of disk, 2 groups of prominences on opposite limbs.
The new active region has moved further onto the disk and is showing an associated filament ...
The seeing conditions were better than yesterday
Lunt LS60THa, ZWO ASI1600MM and SharpCap capture software

My undergrad roommate worked at the Big Bear Solar Observatory during the summer. One of his jobs was to be tour guide. He said in nearly every tour they would ask "how far can this telescope see?" He explained that they only pointed it at the sun, and that you could see stars much farther away without any telescope. This would draw blank looks and some confusion. He quickly learned to just say "93 million miles!", which they thought was very impressive.

Nice photos.

Here's an interesting arrangement of six months worth of solar images shown on Tuesday's APOD.

SpottedSun_Sanli_960.jpg


Explanation: Why is our Sun so active now?No one is sure. An increase in surface activity was expected because our Sun is approaching solar maximum in 2025.However, last month our Sun sprouted more sunspots than in any month during the entire previous 11-year solar cycle -- and even dating back to 2002.The featured picture is a composite of images taken every day from January to June by NASA's Solar Dynamic Observatory. Showing a high abundance of sunspots, large individual spots can be tracked across the Sun's disk, left to right, over about two weeks. As a solar cycle continues, sunspots typically appear closer to the equator. Sunspots are just one way that our Sun displays surface activity -- another is flares and coronal mass ejections (CMEs) that expel particles out into the Solar System.Since these particles can affect astronauts and electronics, tracking surface disturbances is of more than aesthetic value. Conversely, solar activity can have very high aesthetic value -- in the Earth's atmosphere when they trigger aurora.
