Description

Hi Folks,

Taken thru my Hyperstar lens over 2 nights, total of 4 hours integration time. I was trying to collimate my Hyperstar which was quite a challenge and in the process I imaged this amazing red nebulous object which was quite fascinating. At some point I realised with the Help of Dean at Starizona that the collimation could not be improved any further and that the sensor was tilted. I am hence now aiming to sort this out shortly to eliminate my elongated stars at the edges. Nevertheless I added the 2 nights together with DSS to create this image. Hope you like it, any comments welcome
