IOTW: Diego Colonello’s Lagoon Nebula

Name:
Diego Colonnello

Object:
M8

Description:
I wanted to test my Telescope after replacing the secondary mirror for a bigger one, i calculated that my old secondary’s 100% illumination was about 7 mm and my sensor is about 18 wide, so by replacing the secondary the 100 % illumination now covers all the sensor, this is the result…. M8 ha 10 x 300 oiii 10 x 300 sii 10 x 300 Some how i have less vignette or nasty gradients from the filters, this photo has no Flats on it. This is a real difference in comparison with the way it was behaving before, now it is a new telescope…..
