Astrophotography / Re: Mosaic of Orion's Belt

Last post by Carole - Jan 21, 2025, 13:55:23

The Altair Astro AA24CFX camera has the same sensor as my old Nikon Z6.  The main difference I'm finding is the ability to use a low gain value without seeing the dreaded Nikon coloured concentric rings.  However, I'm experiencing issues with some bright bands appearing in lights and darks.  Although they calibrate out, they leave additional unwanted noise behind.  Altair Astro support tells me this is a problem with their latest drivers which they hope to fix soon.  So it's not the best introduction to the world of dedicated astro-cameras!

I have only once tried a OSC cooled camera which was CCD.  I had already started using Mono CCD and thought it might speed up capture if I could do colour on the OSC and add Luminance to it.  But it caused me so many problems that I didn't have with mono, that I soon re-sold it and stuck to Mono, but each to their own.

4 hours in total, Carole.  Yes, it'll certainly be good, having more free time

Astrophotography / Re: Jupiter

Nice set of images Duncan!  Are they all taken at the same scale, so the relative sizes are how they would appear visually in a scope?

Thanks Mark.

All exactly the same setup and no resizing. No barlows or powermates involved. I bought this scope for planets, small galaxies and planetary nebs. Looks like it'll produce the goods once I collimate it with my new (today!) TSCOLLIT collimation scope.

Oh Fabulous Mark.  I can see we are going to get a lot more from you now you have more time to spare for your hobby. 

I see this is from your new OSC camera.  How are you finding it compared to DSLR?

How many hours total exposure Mark?

You have been busy Duncan, with Saturn, Mars and Jupiter.

Good work.
