Meade Deep Sky Imager

            The logbook of a beginner in sky imaging

José R. Torres

 

For a long time I have been tempted to try out sky imaging, but I was never convinced to give the big step forward. The reason was that the equatorial wedge of my telescope was undersized, and I did not own an adequate imaging system. But finally I solved it. My 10" Meade LX200 Classsic has been updated with a superwedge and a Deep Sky Imager (DSI) as introductory imager. I am having rewards and deceptions, but the experience is well worth. This section is a matter of logbook. Click on the different dates to link the respective webpages, and see the images got.

 

 The first contact

    22 Jan 2005 - The first contact with sky imaging, very promising, too much to learn. The moon was 89% illuminated.

    4 Feb 2005 - Second session, some problems solved. The night was foggy and light polluted. Occasional clouds crossed the sky.

 

 Learning more

    12 Feb 2005 - Third session. IR filter removed. Good and transparent night, although LM was <5.5. The F/D:3.3 reducer was disappointing. All images were taken at 6.3.

    15 Apr 2005 - Forth session. Good images with the new F/D:3.3 focal reducer / field flatenner, although this accessory was shown deficient at low light levels. The night was transparent and occasionally windy. The Moon was present the first part of the night.

 

 Going deeper

    May-September - Four sessions. Some tough objects such as Palomar 4, Pease 1 or the Corona Borealis Galaxy Cluster, together with other well known (Omega and Trifid nebula, etc).

    November-December - Two sessions. More objects and new processing techniques to compensate the deficient colour correction of the DSI. Some objects of the former session have been corrected.
