Alec Posted September 21, 2020 Share Posted September 21, 2020 Just a quick image session last night, really to try the collamation as i never done this before. NGC7000 10 x 180 unity gain plus 5 darks for the amp glow with the ZWO ASI 294MC Pro. Do i need to do any more collamation wise? +Glafnazur, +seven_legs, Sheila and 1 other 4 Link to comment Share on other sites More sharing options...

Bottletopburly Posted September 21, 2020 Share Posted September 21, 2020 I would compare to other images of the same scope , small stars look to have a double spike , centre of large stars look saturated but not seeing a comparable image before of this scope hard to tell Alec .

+Graham Posted September 21, 2020 Share Posted September 21, 2020 Only way to really see if it is collimated is to do a star test. The image looks great Link to comment Share on other sites More sharing options...

Alec Posted September 21, 2020 Author Share Posted September 21, 2020 I did this image before collimating and you can clearly see the stars to the left are elongated before adjustments. One thing I’ve not touched is the tilt on the focuser. Only did the spider at the front first then, tilting the mirror Link to comment Share on other sites More sharing options...
