Widefield picture (camera only, no scope), using a hand made tracking device: turn the screw once per minute to follow the stars! 3 * 3 minutes

Not great yet but I'll do other tests soon !

Nice night yesterday - some more pictures of the same objects, rephotographed with longer exposures

M27, the Dumbbell Nebula

I wonder what that is!

Albireo, twin star

M5, globular star cluster

M17, the Swan/Omega Nebula

M11, Wild Duck Cluster

Reprocessed directly from the RAW files using dcraw with DSS - much better without the noise reduction.

Some quick Sony NEX-5 pics

The conditions are really bad (white zone in the middle of Tokyo, 30 celsius, roof balcony), but for the fun I tried to attachmy Sony NEX-5 to the telescope, and tried a few objects at random (can't even remember what I shot) with the following settings for each object:
- 15 exposures of 5 seconds each
- ISO 3200
- 5 darks
- No noise reduction (or at least as little as possible)
- Sony ARW (raw) format
- Meade LT6 with Antares F6.3 focal reducer

We are interrupting this broadcast for a view (in blue) of the current radioactivity levels in Tokyo, in microsieverts/h for 15th and 16th of course. As you can see, pretty low (click image to enlarge)!

Same image processed by Warren/rigel123




And same image, re-reprocessed by me

Same image with some more processing via Masks in Gimp. Much better, the core is visible :)
