Hello,

 

i made tests on M57, trying lucky imaging.

 

Setup : SCT 9.25" F/D 10 + IMX178 color sensor camera

 

I used sharpcap and livestacking, combining 2 pictures :

- 534 exposures 3s each gain 400/510
- 1122 exposures 1.5s each gain 510/510

 

I think it is my most detailed M57.

I am quite pleased with the result.

 

Clear skies.

 

Alain

Hello,

 

here is a comparison between :

- 3s exposure time with FWHM about 4

- 1.5s exposure time with FWHM about 2.2

- M57 with HST

The result with 1.5s exposure time shows a bit more details.
