Re: Sol from the 12th of October 2020.

Hi, Eric

This is really nice work. The texture of this AR is so vivid it almost makes me uncomfortable.
The seeing for me here was really bad although the sky was a cloudless blue.
I'll try again next day.

Re: Ha 11.10.2020 AR2774 + AR2775

Hi Josef

You have some beautiful smooth tones in your chromosphere images and nice detail in the prominences.
Did you use both the DayStar Quantum 0,6À + Lunt LS50 for the prominences or just the DayStar Quantum 0,6À ?

AR on Friday, Oct 9

Although the seeing was abysmal, I used a Celestron 180 Mak in a new configuration for this session.: A full aperture ERF + 35 nm Ha on the nose of a new 2 inch 1.5X telecentric + ASI290 camera. The new telecentric avoids the use of reducers that, for me, always caused more problems than they solved...

Re: Advice requested on Quantum filter purchase

Thanks for the reply, Peter.Your images are very persuasive. They show good detail, both in the proms and chromosphere.

A very worthwhile day (Sept 27)

This day was worth waiting for all season long. There were very obvious very good seeing conditions that lasted for a good 20 to 30 seconds where very delicate fibrils were visible and fairly steady.There was little in way of haze and the shutter speed was fast with little gain required. All this ha...

Advice requested on Quantum filter purchase

In the next month or so, I will be ordering a Quantum filter from Daystar. I’m interested in the best choice for prominence imaging (my main interest when I first started solar imaging). I know that prominences are best imaged with wider bandwidths (these provide high contrast images according to Da...

Features from Sept 22

With the cooler weather came really poor skies, either tolerable with no significant solar features or interesting features with poor seeing.
The images below were taken through hazy cloud cover.

Proms from Aug 31

Both these proms were taken using a 180 mm Mak in poor seeing. Both these proms were were pretty dim and, so, required heavier processing to extract details. A Quark Combo was used at f/15 (prime focus).

There were quite a few proms on the limb today but some were barely visible. One such prom made a very nice composition with a nearby filament. Lou The following 3 images were taken using a single stacked LS152. ghost.jpg 422.jpg 114b.jpg The next image was taken with a 180 mm Mak 75(7).jpg

Departing AR2770 on Aug 15

An oppressively hot day with a short recording session. I didn't see any notable proms during my session although I see that others managed to image one. The one noteworthy event was AR2770 about to round the bend and a curious butterfly shaped AR. I used an LS152 here .

I'm glad you were able to squeeze some data out of that threatening looking sky. My sky, here, was like yours but with no holes.

Re: AR12678 31st July

Hi, Mark

The first Ha image (in bw) really stood out for me, at least, with its very fine feathery texture.
It's great to have such large scale features to look at and image these days in good seeing and here's hoping it
stays around for a while.
