Ant Posted July 3, 2008 Share Posted July 3, 2008 This is the first image I have taken through the new newt.The collimation is OK ish - having a few issues with that since removing everything.The focus seems OK. This is a one second image, 300D 100% but cropped.Any idea what is causing it?I've got a spare part for the focuser on order, so the 300D is connected using the direct SLR thread - and therefore I have no place for the LPR filter. So it it wedged in on the scope side of the focus assembly. As far as I can tell it is in flat...Maybe I should just take it out and see what I get... going to go off and do that.But any other suggestions gratefully received.An Link to comment Share on other sites More sharing options...

MikeD Posted July 9, 2008 Share Posted July 9, 2008 That is caused by internal reflections, light bouncing between the CCD and LP filter I get it with my Ha filter, you my still get some even with the filter flat though it will not look so bad when it is sermetrical with the stars Link to comment Share on other sites More sharing options...
Ant Posted July 9, 2008 Author Share Posted July 9, 2008 I use the filter on all my images and never had it before. Very odd.Cheers Mike, at least I know that if I get it again it's normal.Ant Link to comment Share on other sites More sharing options...
Kaptain Klevtsov Posted July 9, 2008 Share Posted July 9, 2008 You'll only notice it on very bright stars, otherwise its too dim to see.Like Mike said, quite normal.Kaptain Klevtsov Link to comment Share on other sites More sharing options...
Ant Posted July 9, 2008 Author Share Posted July 9, 2008 Ah that's probably why then... that star was Deneb. All the other "proper" images had 5th mag stars brightest! Brilliant, thanks guys.Ant Link to comment Share on other sites More sharing options...
