Target is my favorite M43

setup is a Skywatcher Evostar 80ED DS-Pro telescope mounted onto a Skywatcher NEQ6 PRO Synscan
Camera is a modified Canon D600 all controlled via a laptop

28 images at 60s and 120s exposures were stacked and the best 80% were stacked to get the image

I use either Deep Sky Stacker (free) or Pixinsight which is a dedicated astro image processing package but thats €230

I'm just getting back into it after a break as I was working away past few years

Is that not a planet in the top left then? Looks pretty spherical.


It's a really big star.

A wee google tells me M43 is a H-II nebula, meaning it's a massive cloud of mostly hydrogen and is a nursery for new stars. Stars form in awesome clouds like that as the dust slowly comes together under its own gravitational attraction. Note that it's many lightyears across and swirling all over the place (at a rate which is very slow to the human eye, but for something on that scale even the slightest bit of relative movement is in fact a colossal shift), which explains why the whole thing hasn't smooshed together into one single mega-star.

The "II" in H-II is chemistry lingo for 'ionised', which happens because high energy radiation from the new stars blasts all the electrons into an excited state. When the electrons return to their ground state they re-emit the radiation as red light, hence the red tint of the nebula.

Having just googled a ton about M43, I now find myself wondering if you don't mean M42 aka the Orion Nebula?

That's mostly M42, M43 aka De Mairan's is the smaller nebula with the single bright star... Do you use a Bahtinov mask for focusing?

The running man is an interesting target too - well worth a try. Smile

I told you you'd need a proper mount at some point - good call on the ED80 too. Do you still use the newt for observation work?

It's an Infra-Red image of a really acrid post Xmas dinner fart.

yeah M42 dominates the frame but I tend to center on the bright star in M43 and I do like trying to draw out the detail

I use my camera software to focus using FWHM

yeah the ED80 is a good bit of kit as is the mount, I loaned my mate the Newt

Telescope £470
Mount £1000
Camera (astro modified) £350
Reducer for the camera £165
Light pollution filter (req if you live near a city) £130
assorted cables & power supplies £100

Laptop to control it all but almost all the software I use is freeware
I use remote desktop from my room to control the laptop
so I can stay nice and warm indoors as taking a couple of hundred long exposures when its - 3 deg outside is not good for your health

Here's my best M42 (and M43).

Similar telescope/mount, but different camera (SXVR-H694)

see you have sat trail issues the same as I do LOL
very nice image
I'm hoping that my recent work in setting up the tracking scope pays off and I can get up to 5 min exposures
any more than that and the LP kills everything

again very nice image Thumbs Up
