Re: Remarkable days of the Cycle-24.

Very nice indeed, Valery. I can’t wait for these days to return. Thanks for reminding us of the good times. Stu. A large aperture H-a telescope still can show (in details!) a lot of interesting things - prominences, spiculaes, dark filaments, small active areas and rapid changes in them all. My pai...

Remarkable days of the Cycle-24.

Hi all, Browsing my deep archives of the Cycle-24 images I stopped at the Oct.22 2014 folder. It contains several remarcable images of the Great Solar Spot 2014. It was easily visible by a naked eye. Here is the images of this spot as it was seen in CaK and Ha bands. Imaging setup: ARIES 2 bands ful...

Re: Beautiful High-Res HA image 22Nov19

Hi Alfred,

I took a liberty to process your image a bit further. Here is the result. So, your seeing is even better and the setup has better potential than it seems on the first glance.

Right click on the image and open it in a different window to see it in a full resolution.

Re: Took my Lunt LS50T apart to measure stuff - interesting results...

Looks like you are correct.

Can you measure the actual diameter of the etalon itself?

Re: Full Disc & AR2752 | Nov 18th 2019

Excellentt results, Marty

I like the high res of the AR the most.

FD, IMHO, is somewhat over sharpened and too contrasty. I'd advice to make less agressive processing for a FD images.

BTW. My company is ARIES, not Aires. :)

Re: Anybody going to catch the Mercury Transit?

They give us a good chances to catch Mercury - first and second contacts and some time of the transit begin.
The colser to the transit the better they adjust their forecast.
I will use my 150mm refractor stopped to 111mm with a Quark Combo at F/27 and Basler 1920-155 camera.

How do you rate the etalons Valery?
My conservative estimation is that they are better than some expensive and larger 0,3A etalons.

Re: Stacking two external Lunt DS filters

I'm a double SM60 external stack user....being able to rotate one etalon relative to the other is almost mandatory. I'd assume the same for two Lunt filters. Valery, I like the theory, but where do you get optical circular filters of the size needed? Then there's the cost $$$ of a special adaptor p...

Re: Stacking two external Lunt DS filters

It is a mistake to use two etalons which are rated as Double stacked model (which require more tilt to come to H-a core). The pair must be: 1. Standard LS60FHa etalon for single stack view. Require very very little to no tilt to come to H-a core. This etalon must be main etalon and installed on the ...

Hi all, I need your little but important help, friends. Here are two images which were taken not too far apart (in time) from the same location but through two different telescopes and different etalons. Left image was taken with F/30 (on the etalon) and right image was taken with F/42 (on the etalo...

No worries Valery, I just wanted to clarify if the restoration referred to the image alignment/stacking or the entire image processing sequence.

It referres to a full process. All stages and components are important.
