Kan APP eigenlijk defecte kolommen wegwerken (vast wel) @bula , ik schat in dat dit met een bad pixel map gebeurt? In PixInsight moet ik dit namelijk handmatig nog extra aangeven (om het efficiënter te maken denk ik).
Prachtig spul hoor Kees, dit ligt nog wat jaartjes sparen in mijn toekomst. :)

Musquetier started the topic Sensor reiniging in the forum Methoden en Technieken 9 years, 4 months ago
Op mijn sensor zaten een maand of wat geleden ineens onverwachts enkele vlekjes (geen idee waar die vandaan kwamen).
Wat ik ook probeer om mijn sensor weer brandschoon te krijgen, er blijven altijd reinigingsstrepen achter en soms ook enkele stofjes. Is dit iets wat ik maar moet accepteren en met FLATS neutraliseren?
Ik gebruik speciale…[Read more]

Funktionele test met SGP, een serie darks frames maken. Dat werkt prima. Ik heb 1 bad column in de sensor en dat mogen er 2 zijn voor een classs 2 sensor dus dat is boffen.QHY16200-shooting-darks-SGP

When ticking the option remove LP in the calibration fase, retain the previous selection, as in many cases the LP is for all the X numbers of frames the same. Allow these boxes to be moved/deleted in the subsequent frames …

Hi all,
I have really made great progress in the last few weeks and the beta team has been very valuable as well. APP is being tested on different platforms and it will run on Windows, MacOS and Linux operating systems. So we are definitely getting nearer to the moment that APP will be released.
Due to the testing and tuning of APP on different…[Read more]

Hi Marc,
There are some RFCs to change the preview filters sliders and I am planning to acccelate this using GPUs, so possible the looks and feel will soon change. Maybe it’s best to wait for the improvement before we make instructions on how to use this? I realise this need some explanation. For instance the black, white, gamma sliders can…[Read more]

Dat denk ik niet, de eenvoud van een astro-gemodificeerde DSLR blijft een groot pluspunt. Alleen al de koppeling aan een telescoop, M48 Canon ring erop en klik, klaar. Maar voordat een CCD camera erop zit ben je een flinke puzzel verder. In mijn geval hou je dan puzzelstukken (ringen) over en kom ik er 1 te kort. SGP werkt goed met de QHY16200,…[Read more]

Could you expand the workflow with a “how to” use the right panel (black, white, gamma, stretch etc?, including the threshold sliders?).

Haverkamp replied to the topic Data calibration workflow and processing in APP in the forum Methoden en Technieken 9 years, 4 months ago
It was a pleasure to make this workflow, I hope it will help with your data processing ;-)
Yes, I think you need to increase the exposure time of your subs to get better quality. The lokation (background) of your data is at 0.01 or 1 % of the data range. This is very low. You can easily make 15 minute subs. The read noise will be less of a…[Read more]

Groenewold replied to the topic Data calibration workflow and processing in APP in the forum Methoden en Technieken 9 years, 4 months ago
Excellent! I made a final stack and the results remain rather similar, it’s clear I need to take way longer subs I think with H-alpha (as shown by @chrisvdberge on his site). What I do notice in my data is the regular background pattern in the final stack, do you notice that? Diagonal from top left to bottom right, it’s in my data but I wonder…[Read more]

About the registration progress:
the progress bar for saving registered frames is fixed in the next version that I’ll release. The progress bar during registration works fine I believe, but I’ll check it 😉

Hi Scott,
Regarding the interface suggestion. Yes that might be a good idea ;-)
Now , you can only see that the process completed by looking at the results in the file list and the status of the ligths. When the lights go through the processes, you’ll see
CA = calibrated
STAR = stars analysed
REG = registered
NORM = normalised

To clarify the “– Little bug: The progress bar during registration does not update during the processing. (Rob)” – when I click on “Start Registration”, the progress bar works correctly. When I click on “Save”, it displays 5% progress and stays there until it’s done saving.

Rosen replied to the topic APP Request For Change / Suggestions in the forum Astro Pixel Processor Beta 9 years, 4 months ago
Minor interface suggestion- when doing various processing steps, APP displays a progress bar and window showing the percentage completed. When done, the progress bar goes away and you’re often left with a screen that looks much like the screen that started that process. If the progress bar/window stayed on the screen showing 100% with an OK b…[Read more]

Wat een gepriegel. Ik ben benieuwd hoe de hele setup je gaat bevallen, vooral de postprocessing die met een factor 4 toeneemt? De resultaten daarentegen … daar verheug ik me nu al op. Hang je de DSLR volledig aan de wilgen?

Since I am only working on 5 frames to illustrate a workflow, I now use the following settings

5) Normalize
Data normalization is performed.
We keep everything at default settings.
All your light frames will be normalized for lokation and dispersion relative to your reference frame. Which is the top frame in the file list.
APP wil
1) calculate normalization parameters,
2) then perform normalization and
3) then perform noise and SNR…[Read more]

4) registration,
we turn distortion correction on, the rest stays at default.
APP will report the results again in the file list:
1) the registration error in pixels is shown together with the amount of stars that were used in registering the frames to the chosen reference frame. The reference frame waschosen automatically after star analysis.…[Read more]
