Looking for some FITS files fresh from your camera

[Ags]

I am amusing myself by writing a browser based FITS image viewer. At the moment it loads whatever comes out of my ASI485MC, but I would like to try it on other FITS files from other cameras. I would appreciate it if anyone can provide a frame or two from other cameras. I am particularly keen on getting a frame from a 533MC as that is a camera I am planning on getting, or a frame from an OSC with a Bayer matrix other than RGGB.

Here's an Ha frame from an ASI6200MM. It's 116.7MB at 9576 x 6388 pixels so will test your handling of large files. 🙂

They don't come much bigger, thanks.

Single frame from an ASI585MC. A more normal size at 3840 x 2160. It's a colour image, although there doesn't seem to be much colour in that sub

I have a 533 colour cam and clouds

Will upload a couple here soon as I can

@symmetal It's a lovely sub but the browser times out when handling it... I can think of a few workarounds but will have to do a bit of coding.

It's because that file is so large its warping spacetime

[Ags]

The 585 loads but quite slowly, I need to multithread the loading if possible.

Here is @symmetal's sub loaded in my app. I cheated - I binned it 3x3!

opps forgot, sorry. here's a light dark and bias from svbony533mc hope it helps.

Good to get a non-ZWO camera! Maybe they do FITS differently.

It is an interesting challenge. AstroArt is saving the data as 32-bit floating point (I think) and the color info is structured differently from a raw FITS from a camera that includes the bayer matrix. That's a lot of stuff I don't currently handle, so I'll come back to this one. I see astroart is setting the SIMPLE header to NaN - oopsy!

I can provide something over 38 thousand such. Unfortunately I am frantically busy preparing to return to La Palma tomorrow. Perhaps I'll send you a few when I get there.

Thank you, there is no hurry, this is just a little side project that I am not rushing to finish.

I have the ZWO 533MC Pro, I can grab a couple off of the ASI Air......

back soon...

Here you go Agnes...

Mine were via Nina btw not asiair btw in case it matters

[Ags]

Some real progress, although it was painful getting there!. I handle different Bayer patterns like RGGB or GRBG dynamically. I can load ASI6200MM images (by sampling the image and not drawing every source pixel). I also handle both mono and RGB images. The HTML canvas I use is RGB regardless. Here is the 6200 monster frame loaded in the viewer.

Looking good Ags. Are you using the cfitsio library to load the images and extract header info or are you doing it from scratch? You could display image info from the header in the area on the right. 😉

Alan

[Ags]

I started with fits.js but I have been modifying it heavily. I am going to add a header display option.

as far as I know cfitsio doesn't have a Javascript option.

Well, I found a few issues so I reimplemented everything from scratch. I took out a lot of dead code from the fits.js library so it is mostly my code now.
