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.

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.

Hi all,

A small solar flare as seen through a classic C8 telescope equipped with the ARIES full aperture DERF, PST Mod2 Ha filter and b/w camera.

Thanks for looking.

Excellent resolution on the first image. I obtained very similar images when the filter was somewhat off band.

Dark filament in 3-D through C8 telescope.

Hi all,

Here is the image of a large dark filament in H-a. Image taken with C8 telescope equipped with full aperture ARIES DERF (two bands).
The dark filament has almost 3-D view.

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.

Somehow the image becomes much darker that it was when I sent it to Alfred after processing processing.

Re: Importance of the image restoration in the solar imaging.

Just looking at the stacked RAW, I knew it would process up to a workable image. Seeing conditions were clearly pretty good to me just seeing the RAW. When I see fairly smooth, high contrast edges on spicules, seeing is pretty much good. So processing this took very little effort, but that's becaus...

Of course, such a scale is impossible without a barlow lens, especially with IMX174 chip.

Re: Time for selling...

I do not believe that we are living exactly in the moment of solar spots disappearing forever or for a long time. All scientists need to feed their families. So, they need to create dramatic sensations. Otherwise governments will tell them - please, find another jobs.
