SPA-2 compared to Hubble at Cat's Eye Nebula
I was curious to see what the 70 cm SPA-2 in Spain could do compared to the marvellous detail in the Hubble Cat's Eye Nebula images ...
Here's my go at 5x OneClick from SPA-2 in HSO (AstroPixelProcessor to RGB => RGB channels in Photoshop... The S data is the source of the detail in the core. Not bad, I'm thinking... Perhaps others could pull out more? (OneClick data from 15 March, 4 August, 28 September, 7 November, 11 November)
Dataset from which the image was processed
NGC 6543
