Slowly getting to know the ST-8i

Hmmmm... this is fun - working with FIT files is interesting. It's hard to know how to process them until I get some more experience with them. Anyway - here's tonights' experiment (in between cloud banks). LOL! The greys were smoother than it shows here - heavens knows what happened...

Would that be jpeg compression showing up the stretched or DDP'd data?

Dang Mike! Found it. I was exporting a TIF out of CCDsoft and didn't realise that it saves in 8-bit colour space, not 16. Arggh! So then thistime I saved the aligned images as a FITS and this was still 16-bit when it landed. FITS Liberator opened as 16-bit into Photoshop just fine after that.

This is a little smoother.

That second one looks very nice Chris! very smooth and detailed..
Must be some learning to do compared to DSLR files.
cheers Gary

Very nice

Is this similar in exposure to your last one done with the 350d ?
Tak FS-102, 350d 5 frames @ISO800, 2 minutes per ?

This image is made up of 5x10sec, 5x20sec, 5x30sec, 5x60sec and 5x90sec images. I haven't yet included the 10, 20 and 30-minute subs.

Do you realise how bloody annoying that field is to a ST7 owner.

Well done Chris, nice image.

Hehe... The ST7 would be fantastic for small planetary nebs though...

Omaroo (Chris Malikoff) · #11 09-02-2009, 01:32 PM

Thanks Alex & Jeff

Jeff - the ST-7 has it's day too. I've seen some great shots from these cameras - including yours.

I've added another 30 mins of data - so the nebulosity is starting to gain some quality I think, and I'm starting to like the subtelty of this camera. Anyways - I'll take some more soon.

The version uploaded to IIS here has been downsized to 200K and is starting to really degrade in comparison - but it's handier

very nice depth... starting to get a 3d like appearance in the core area...

Nice shots....good depth in the pics.

Thanks Alex & Reno

I can't wait to get back out there with some filters on the front. I have an OIII, I just need an Ha and SII so that I can dabble with the HST palette. Anyone have any advice on this?
