Experiences with the Meade LX10, part 6


LX10


Here are some more result of a 58 mm and 135 mm camera lens and Alpha-Mini CCD riding on the LX10. The lenses are F/2.0 and F/2.8 but the diaphragm and reduced to about f/4 to get nice point stars.

A tried to combine several CCD pictures, but the results where first disappointing. The stars tend to spread out larger. Later I found out the combining only works if the exposures are from the same series using the same guide star. If not, adding is possible but due to distorsion of lens and rotation and so on they do not fit perfectly. Personally I prefer single exposures but the light pollution is large here. The CCD is overloaded for exposures longer then 3 minutes (f/4). Visually, I can see stars till magnitude to about 3.5.

double cluster

The famous double cluster NGC 869/884. using the 58mm photo lens on the CCD camera.

M45

M45

M45 or pleiades, You can see faintly the (normally blue) nebula around the stars.

M31

Andromeda galaxy, Messier 31

M33

Messier 33 or Pinwheel Galaxy. Faint, large object.

NGC1499

NGC1499 or California Nebula. This is a combined image. The result is almost the same as a single exposure except that the nebula becomes less grainy.

saturn and moon 2001-11-3

A was a little late and in a hurry. First I missed the moment when Saturn dissapeared behind the Moon and then had some software problems. Finally I almost missed the re-entry completely. This is only a kind of software preview mode so I can not enhanced the picture much more. Only 8 bit BMP. Next time I should be better prepared.


End  of februari 2002 , I sold my LX10 since it was more or less redundant to my  8 inch LX200. I liked it a lot , but the LX200 is just much more confortable. No more star hopping to find objects.
