More Mesu-guided  images added to Astrophotos Page 4.

Astrophotography 2

These are the first images from my modded EOS550d (IR cut filter removed).  Because there is some light pollution (fortunately not loads) where I am, there is an Astronomic CLS filter in the optical path here.

I think that if you’re realistic with your expectations, and stick to (relatively) larger and brighter objects, you will be pretty happy with what this device can capture.  Some of these images are single subs, with no darks!  I know I’ve got a bit to learn about processing, so please forgive the noise and colour. For once, you can click on the images for bigger versions.

Where two images are shown of the same subject, one will usually show a (scaled-down) full frame, with a crop of the object of interest, from the same source image.

Most are taken with the Wave 115 on my belt modded EQ6, guided with SSAG and ST80, and are a stack of 5 5min exposures at 1600asa, with a basic dark subtraction.

I know most of you will know what they are, but I have added some info for those who are ‘new to’ the topic (I won’t say ‘learning’, because I think we’re all doing that.)

Afraid the max size shown here is 1024 pixels wide.

North America Nebula, in Cygnus - taken with an 85mm lens.

Andromeda Galaxy (M31).

2.5 Million Light Years away.

The Pacman Nebula, NGC281, in Cassiopeia.  9,200 Light Years away.

A part of the Veil Nebula, in Cygnus, best guesses put this 1500 Light Years away.

Galaxy M33, in Triangulum.  3 Million Light Years away.

One of my first shots with this set up.  This is a single exposure of the famous Dumbell Nebula in Vulpecula.  No stacking and no dark frame. Just 5 mins at 1600 asa. Lots of hot pixels in this, but if you click on the image below, you’ll see the full resolution crop.

(Only a 250kB file)

The Crab Nebula (M1) in Taurus.

6,500 Light Years away, expanding at 1,500km per sec, according to the gurus

The Bubble Nebula (Caldwell 11, NGC 7635) in Cassiopeia.

11,000 Light Years away.

Open Cluster M52 shown top right in the full frame.

The Crescent Nebula, again 5 frames, each one 5 mins

M51, just a single exposure here, and from very low in the sky.  Hoping to get a better shot when it’s higher and the sky is clear longer.  Not too impressive I know.


An old favourite, M42 - the Orion Nebula. Simple composite of a 5 min and a 1 min frame here to keep some detail in the bright centre.

No darks or stacking, and very low in the sky, so hoping to get a better shot soon. Single 5 min frame at 800iso. Clicking this image will open the full resolution (but compressed to 1.4MB) file.  Spot the satellite trail - doh.

Flame and HorseHead Nebula, taken with a 300mm Lens, a composite of 3 five minute exposures.  Surprised this came out so well.
