Re: Daystar 60mm Solar Scout Picture

Hi,
I had a SS60-DS for trial. It was supposed to be a good one.
Your Image is far better than the one I made.
Looks very good.

Re: First solar light for a T300

Thanks for the comments. I added in the system a stellar Ha system, so we are in Ha with 7nm bandwidth. I tried in KLine, but the turbulence was soooo bad. Yes, it is the successor of the 250mm. I expected to find a bigger slow optic in the range of 350mm, but couldn't find. This 300mm is at f6; the...

First solar light for a T300

Hi!,

I bought second hand a 300mm newtonian and made its first light on the sun.
There was no spot. Simply granulation.

Re: Truss Solar Newton T250 for Ha and CaK

Thank you for the comments. Some words about the system. Optically, the design values are: F/D ~7, to be combined later to a telecentric x4 and come to high focal ratio number for imaging with a Halpha etalon. D is ~250mm; F is about 1700mm.   Some words about the system. The principle is a herschel...

Truss Solar Newton T250 for Ha and CaK

I'm renewing some of my equipment. I bought a camera and FSQ106 and will probably go for a bigger solar scope also. From my astrogear, the solar newton is for sale. Truss Solar Newton T250 for Ha and CaK Works also with the solar continuum Works also under the G band (430nm) The truss tube and mirro...

Re: Denoise

Hello Bruce, Thank you for your comments on my image. To give some words on it, it has been made with a D250mm f7 newton coupled with a custom design telecentric x5. The resulting focal length is 8750mm, F/D35. These numbers are normally too big for my area where a very common seeing dominates. But ...

Re: Denoise

The post is back here :-) Thank you. Bruce, indeed a very long description, where I recognize the process. Maybe I was not patient enough with solar imaging to find out the right settings. I stopped using it in about 2014. Here is my last solar pic, stacked with 100 pics, sharpened with wavelets, an...

Re: Solar Granulation with the Daystar Sodium Quark, Airylab HaT and SSM Firecapture Plugin - 26th July

Good that fire capture supports the SSM.
I asked to the fire capture developer some year ago for it, but he had no interest and/or time.
Is the plugin working with the SSM from Airylab?

Re: Denoise

I tried several denoising tools some years ago. I finally remained with neatimage. But I after some use, I was not convinced by the results, and stop using it. For solar imaging, we look for the finest detail. The noise is generally at a very high frequency level. There is no need to denoise low fre...

Re: Mosiac of the active region 7/16

A mosaic at high resolution is very "hazardous" to me.
Too much depend on the seeing, especially for 6 frames. All frames must be good.

Re: AR moving to the limb on July 18

I like High res. shot, this one also :-)
For noise reduction I often apply a very noise reduction. I use a gaussian blur, starting at 0.3 pixel, then adjusting.
