First worthwhile results from a high res set up

This is the latest start to solar imaging in my memory due to lack of solar features and poor seeing. The sky had variable patches of haze with some areas of interest on the sun. It was a good day to test an f/30 system using a just acquired TZ3 Baader telecentric carrying a Quark Combo chromosphere...

Re: ARs on Sept 6

Hi, Solarchatted

I almost lost your question in the middle of this old post. Sorry about the delay.

For these white light images, I used Baader 3.8 film in front of my AR152 refractor.

Re: Today's SUN (20171202) | LUNT50 images

Hi, Pedro

Thank you for your continued postings at a time when some people have downgraded weather. I also have to add that when you use a curved
backdrop as in your Lunt50 images you show how meticulous you are in your imaging - a nice touch.

Re: Today's SUN (20171116) + new (vintage) scope

Hi, Pedro

I have to say that the mount on your Tasco scope brings back a lot of flashback memories. It looks very much like the mount that came with my first scope
(a Tasco 4" or 4.25 " newtonian) with its bare right ascension gear and long, tight coiled spring extensions for slewing.

Re: A Walk Across the Sun

Am I right in thinking that the person walking against the sun is located in the bottom wide angle view
in the flat part along the bottom centre just before the little rise (trees)?

Re: Another large prom + more from Oct 24

Thanks, everyone

I should point out that the "double limb" isn't there in the original stacked image. It's the result of selecting out the disc for processing and then pasting it back into the prom layer.

While driving back home from early morning errands, I heard that the weather was going to become heavily overcast at noon (an hour away).

Hi, Hans

Welcome to this board. Be sure and post some solar images when you can and of your surroundings if you wish.
Yes, most people will envy your 320 days (!!) of sunlight especially when some of us live under extended periods of clouds and we "need" to see the sun.

A day full of waiting, with wispy clouds becoming more intense as they approach the sun.Many faint proms, including a fly away, were visible on the full disk after boosting mid level. An LS80 and Lunt152 were used.

Re: Weird bands with LS80Tha/DSII

Hi, Mark These bands are called Newton's rings and are common with some cameras. The solution is usually to tilt the camera slightly. Some people use a tilter specifically made for this purpose. One of the more economical ones is by ZWO shown at https://astronomy-imaging-camera.com/products/accessor...

The first 4 were taken with a Lunt 152 at 3800mm and PGR G3(2.8Mp)and the last was a 2 image mosaic with a Chameleon 3 and the same scope.

Re: Today's prom (Oct 8)

The artifact is actually on both sides of the subject in the dark areas and becomes obvious when I had to boost the contrast a bit.
It doesn't seem to be there in previous images in the same areas when I boosted the midlevels even higher than here.
