Re: halpha sun of the 17th of May

:) Nice capture and processing Stéphane! :)
I was not sure if you combined several frames into 1 disk, or is it just 1 frame from a video of the whole disc ?
I was not sure of your setup.
Could you briefly explain your solar imaging setup ?



Thank you !

Our quiet sun 15th May 2020

Hi Sun lovers ! :) I hope everyone one is well in these difficult times of the SARS-Cov-2 pandemic globally. I am from London, and only got a Quark for H-alpha observations about 1 year ago. I am enjoying the solar minimum. The sun can be incredible even with little activity. It really is not that q...

Re: Some FDs from May 8th '20

Lovely images Stu.
Are those full discs, a mosaic of many frames ?
I wonder if you have problems with Newton Rings, like I do.

Many thanks.

Re: AR12760 April-30 with SW150mm full size DERF and Quark Chromosphere

Hello Valery, Thats really nice ! :bow :bow2 I wonder if your Basler-1920-155 b/w camera has problems with Newton rings at all ? Could you post a photo of your imaging train (or in writing like: D-ERF: 150mm scope:extension tubes (100 mm)- barlowx2-Quark-Reducer-Basler-1920-155 b/w camera) What is t...

Re: Working on Prom/Chrom/Spicule limb shots

Hi Jack,
I have been calibrating my Quark recently, and am waiting to process them. I was looking at my Quark and -5 on the dial showed least detail. Your Quark -5 looks not far from my Quark at -5 or -4, I think a +2 or +3 setting may be near optimal (not sure which one is best on mine yet).

Re: Tried a new technique: Barlow to Quark to Focal Reducer to Camera

Nice work, Jack ! Lovely detailed and high contrast images of the plasma ! :bow :hamster: I wonder the following though: 1) what is the magnifying barlow (x2 or x3 or something else) 2) where is your UV/IR filter (heat); is it a front ERF or a 2 inch uv/ir cut filter somewhere in the imaging train 3...

Re: Using different settings in Autostakkert 3

Hi Mark, Does Autostakkert!3 actually rearrange the frame order according to the quality graph in the centre of the main program window ? When you scroll frame by frame on the right window (the Image video), is the frame you see as you go from frame to the next frame, ranked in order ? Thanks. Magnus

Hello Alexandra/Montana, I have a similar problem with Autostakkert!3. It is usually really good. However, I still don't know how the frames are assessed in terms of quality, and which frames are good, and which frames are bad. I tried scrolling through the video file after Step 2: Analysis.

ImPPG and Sigma query, Seeing conditions -website

Hi All ! I am practising using ImPPG, but cannot really tell what value of Sigma to use in the LRD or the unsharp masking settings. I tried to use ValeryD from cloudynights image which he offered to test for processing. I had a go, and this is what I got (original is 1st, then my image). Has anyone ...

Hi Mark, I welcome your opinion. Visually I think my Quark is ok. Imaging is much harder. Now I will find a nice day to calibrate my Quark to see if I can get better images. Thanks Mark. :D There is so many factors in getting a good image. Thanks for your great website, I used that a lot for my educ...

Thanks Mark. How do you adjust the Quark to be on band, is there an easy way of doing this ? Turn the Quark settings knob to the left or right or midpoint, its very difficult. I thought my telescope/camera combination is not good enough for good detail, but perhaps its my Quark is a "bad Quark"; how...

Re: Prom from 20200404 - Quark/ASI120mm-S

I tried a later video file, and used ImPPG to apply LRD and unsharp masking. It seems less sharp but has fewer unsharp masking artifacts, I think.

Thanks to all.

Thanks Jochen for the encouraging advice. Thanks Mark, yes it was a 16 bit tiff file, no sharpening was ticked. I will have a go using ImPPG, this is probably easier than Registax6, I will have to avoid too much unsharp masking, and get my Sigma values better. I think I am getting the hang of imagin...

Re: Prom from 20200404 - Quark/ASI120mm-S

Hi Alexandra,

I see the spots now, I think it must be processing or noise (?) from Registax6, as the spots are not there from the stacked file (20% of 1000 frames, 16 bit SER, exposure 2.297 ms, gain 71.

I will have another process at the stacked file.

Thanks Alexandra, I am not sure what spots you are seeing. I have more data (possibly better) from a few days later in April, but am not sure if I took the right flats. I will go back and try a reprocess. I could not get ImPPG to do much better than Reg6 ! Can you tell if my Quark is reasonable qual...

Hi, After much time spent on settings and techniques, reading Montana's solar guides (solarnutcase) and Marty's (Wise imaging) videos again and again, I managed to get this after applying flat frames to get rid of Newton's rings and dust spots.

Re: Solar imaging - computer write speed/FPS values?

I agree Marty with you. I have been reading about the various options for SSD and RAM and CPU configurations, and I will try your method first.

Now, it’s time to look for a bargain laptop.

Thanks for the warning about LCD screen sizes, there are problems with setup etc.
