Anywhere Is: Getting even with blue dust, featuring M45 Pleiades open cluster
Image by Sergei Golyshev (reloaded 🙂
I can do it! My own picture of Pleiades with their reflective nebulosity and in their starfield context.
But what amazes me more are those dark lanes to the North-East corner of the image. Almost exactly in that direction resides huge California nebula.
Aquisition time (start of a session): JD 2456659.293831 (01.01.2014 12:03:07 MSK)
Image orientation: straight.
Equipment:
Canon EOS 60D (unmodded) with Canon EF-S 60 mm f/2.8 macro USM lens fitted with Baader Planetarium 2" UHC-S filter on Vixen Polarie star tracker mounted on photo-tripod via Manfrotto 410 Junior geared head.
Some additional modification were added. Since now I’m absolutely sure that Polarie’s payload capacity is 3 kg, I have removed ballhead and replaced it with – yes! – yet another Manfrotto 410. So now this "Anywhere Is SWANS mod. "Control Freak". Very convinient to point and frame, except the fact that altitudes below 15 degrees are unavailadle due to hinderance. And I still have some 400 gramms of unused capacity, which allows me to use a bigger lens.
Aperture 21,5 mm
Focal length 60 mm
Tv = 60 seconds
Av = f/2,8
ISO 3200
Exposures: 60 (plus 30 dark frames, 103 bias frames and 10 fake flat-field frames)
Processing: images were converted to 16 bit .TIFFs, stacked in DSS. Final touches in Photoshop.
Note: fine example of "smaller lens = bigger stars" 🙁
