I suspected along with others comments that the sensor response was a factor. Your comments are very accurate in describing the Fri, 05 Jun 2009 13:12:34 GMT Robin Leadbeater http://tech.groups.yahoo.com/group/staranalyser/message/1489 http://tech.groups.yahoo.com/group/staranalyser/message/1489 Hi David, Congratulations on you first spectrum :-) The dip is at the overlap between the green and red channels and is almost certainly caused by the camera Thu, 04 Jun 2009 14:35:20 GMT davidflee002 http://tech.groups.yahoo.com/group/staranalyser/message/1488 http://tech.groups.yahoo.com/group/staranalyser/message/1488 I finally had a chance to image my first spectrum of Vega. I've had a quick look on the net for examples and it is close but I'm wondering what the dip is just Wed, 27 May 2009 14:06:47 GMT Robin Leadbeater http://tech.groups.yahoo.com/group/staranalyser/message/1487 http://tech.groups.yahoo.com/group/staranalyser/message/1487 Hello Steve, the 8 inch SCT is probably your best bet. (Do you have a 0.6x focal reducer for it? That would help keep the star size small which helps Wed, 27 May 2009 00:42:41 GMT davidflee002 http://tech.groups.yahoo.com/group/staranalyser/message/1486 http://tech.groups.yahoo.com/group/staranalyser/message/1486 ... I actually found a way that will be better than using the locking ring for my purposes. Baader Planetarium makes a T adapter that is a quick release.

Definitely no extra bag with the Star Analyser. I'll have to check with the dealer tomorrow. I also checked the CD and it is Tue, 26 May 2009 05:44:16 GMT ken4optics http://tech.groups.yahoo.com/group/staranalyser/message/1483 http://tech.groups.yahoo.com/group/staranalyser/message/1483 David, I just bought a SA100, the spacer ring was included in a small plastic self-seal bag. It's a very narrow ring about 28mm diamter and about 0.5mm wide.

You should have a separate one in a small bag inside the main Tue, 26 May 2009 05:38:35 GMT Olivier Thizy http://tech.groups.yahoo.com/group/staranalyser/message/1481 http://tech.groups.yahoo.com/group/staranalyser/message/1481 David, Explore the CD (it won't autorun): you should have a document file with the user documentation on it. Otherwise, the on-line manual is the same than the Tue, 26 May 2009 01:34:35 GMT davidflee002 http://tech.groups.yahoo.com/group/staranalyser/message/1480 http://tech.groups.yahoo.com/group/staranalyser/message/1480 What does the locking ring look like? I don't believe I received that either with my Star Analyser 100.
