Subject: tips for a Home Made LPI Focal Reducer Sent: Wednesday, December 29, 2004 00:39:56 From: Dimitri zilber (zilberd@yahoo.fr) I'm the happy owner of an ETX 90EC, a skywatcher 80/400 and a skywatcher newton 130/900. Last month I bought an LPI imager in order du complete my EOS D30 whitch is a little heavy for my telescopes. I am really pleased whith the camera but found that a wider FOV should have been better. Because of christmas I really can't spend much much money on a real focal reducer so I've made one with the front lens of my old 8*21 viewfinder. English is not my language so I put some photos in the mail for explanations.And:There are some samples of the moon (between two snow showers) and of a street light about 50meters away. The acquisition has been made with K3CCDTools in AVI mode.

thank you for posting my idea here's a new pic of the moon that I did yesterday with the focal reducer attach to the LPIAnd more:It is much better than my first try... Capture in AVI with K3CCD 474 frames Processing with registax 75 frames selected and a little wavelet applied regards Dimitri Zilber ![]()
I take another pic witch was in CIF mode and also with the focal recucer. This time the frame rate was 15fps witch is not bad at all (almost like a TuCam) and the FOV is almost the same as the LPI without the focal reducer.I think that I have found my new configuration for imaging saturn tonight : CIF mode (352*288) with the focal reducer at 15fps the atmospheric disturbance was much lighter than at 2fps Dimitri ![]()
