safe haven for tiny formats

Very interesting!

How are you connecting Instax to the rig?

and what size?

I am experimenting with Instax Mini B&W and Color with the Mini 90

Waiting for the new Instax Wide Back

Last night was finally clear and I worked on shooting the Andromeda Galaxy again from about 2am till dawn. I combined all the images from last night with additional ones from September last year and was able to make this image, which I'm quite happy with:



There's plenty of better M31 images but I'm getting better, I think. The multi-night stacking seems to really help. I will continue to "add data" to this stack as the year progresses.

On another note I did some preliminary tests shooting this on Fuji Instax. I should be able to get a good result but I need about 4 hours of imaging time. Hopefully that will happen soon.

Waiting for the new Instax Wide Back

I discovered I can manually put one sheet of Instax Square directly on the rails of my Pentax 67. It fits, and exposes all but two small strips on the left/right of the image (the Instax is nominally 60x60 I think). You have to carefully slip out a sheet from the box after loading it into a normal Instax camera (eliminating the dark slide), in the dark of course, and put it (oriented correctly!) into the Pentax - then put it back into the box after exposure and shoot a "blank" image to send it through the rollers. This may work in other cameras - perhaps in a 6x7 back or even a 2x3 film holder for the little baby Century Graphics, haven't tried since I'm using my 400mm or 500mm lenses on the Pentax.

Thanks!

I will try it

One of my most recent astro pics, noting that Corran is showing some nice stuff here!
I sort of stopped astro once I started with "terrestrial" photography, but I'm sure I'll get out amongst it again.

This is a narowband image of the central portion of Carina nebula, including the star Eta Carinae. I don't really recall the details, but I typically using 4min exposures and stacked 4 to 18 hours of them. Darks applied, no flats or biases. Camera was a ZWO 1600mm pro with 7nm ZWO filters. Scope was a 1000mm focal length F5 newtonian, guided but not dithered.



some other images from that year or so are at https://www.astrobin.com/users/jahnpahwa/ if anyone is keen to check them out

That's incredible, John!

That's incredible, John!

Thank you, mate! Astro was a whole lot of fun.

All your wonderful images are equivalent!

Wow John. Now I'm a bit embarrassed at my results!
