NGC 5139 Omega Centauri
Captured some lunar images between 9pm and 11pm then waited until 1.00am for the sky to darken then captured Omega Centauri. Finished subs at 2.30am, set my darks, put the cover over the scope and went to bed
30 x 3 minute subs
15 x darks
ISO 800
PHD2 guiding
Stacked in DSS
Processed in Startools
My stars on the right hand side of my recent images keep flaring a bit. I’ve pulled apart the OTA, collimated and aligned with a Cheshire and 2 different lasers secondary and primary and looks ok to me nice and concentric. My test images on small and big stars before I image are really good, clean, sharp and nice diffraction spikes.It can’t be focus as the test stars are tight and sharp and if it was coma you would see it on both sides ?
Must be a bit of flexure or something as it’s only on the right hand side off axis
It is a budget Bintel GSO $299 OTA
A bit annoying
Cheers
