RichieJarvis Posted May 21, 2009 Share Posted May 21, 2009 Hi All,I recently brought a Meade .33 Focal Reducer, and decided to have a play last night - Leo was nicely up in the sky around 10:30, so I setup and went for the Leo Triplet.Based upon the FoV, I reckon this has brought my F/7 102 down to around F/3.2 at the cost of large amount of vignetting - I need to sort out the spacing really, but need a custom adaptor to do so. It also had a rather strange effect on the shapes of some of the stars towards the edge, but nevermind Several subs were ruined by the occasional cloud causing the guidecam to lose the guidestar, hence the odd sub counts in this one!Really wish I had captured some Ha data to go with this one now, but nevermind - maybe next year!Heres the image data:Date: 2009-05-20Location: South Common ObservatoryScope: Astro Professional 102ED at approx F/3.2Camera: SXV-H9Exposure (L): 22 x 300 seconds - 1x1Exposure ®: 18 x 200 seconds - 2x2Exposure (G): 21 x 200 seconds - 2x2Exposure (: 22 x 200 seconds - 2x2Guidescope: Williams Optics Zenithstar 66Guidecamera: SX GuideheadThanks for looking!Cheers,Richie Link to comment Share on other sites More sharing options...

Psychobilly Posted May 22, 2009 Share Posted May 22, 2009 Nice image ...Both the Vignetting and the dodgy star shapes are due to trying to use the f3.3 reducer to do something its not really meant to do.... Its really only any good for the tiny sensors in the Meade DSI I , III and LPI's Here's the manual online...http://www.californiastars.net/lx200gps/files/documentation/focalreducer33_pg01.gifhttp://www.californiastars.net/lx200gps/files/documentation/focalreducer33_pg02.gifAnd manulas for a whole range of Meade accessories... and scopes...http://www.californiastars.net/lx200gps/tips.htmlPeter...
