M42 latest attempt

[Explorer 190 MN]

This is my latest attempt at M42

This is only 36min of data from a one shot colour camera, unguided 45 sec exposures on a Edge 8 HD hyperstar system with a Atik 314L colour camera chilled to -15 flat and bias calibrated. Calibrated and stacked in Nebulosity and processed with pixinsight. I will add more data to this as the months go on at the moment M42 is visible for 15 mins from the back garden due to trees. I have recently ordered a mono 314L and LRGB filters along with Narrowband not sure how yet but I will make a combination of the lot and when I figure that out I wil try to make a mosaic of the Orion constellation. I have realy worked hard to pull as much detail from this as possible.

WOW! That's incredible I'm just on M42 right now. 30s at ISO 3200 on my 1100D cooled to 0C with ED80 + FR as below in my sig.

Thank you Gina good luck

Even in Stockholm Orion doesn't rise very high at the moment so that's pretty impressive for a relatively low object, well done.

Thanks dipper,

Here is the best part.. I get 15 mins between my neighbours birch and spruce tree just before sunrise. Thankfully my neighbours have given me the go ahead to take there trees down and also the neighbours next to them..

I have added some more data to this and made a HaR G OIIIB if that makes any sense.

Wow! That's incredible - wonderful shot

Thank you Ginathe original is a bit better as there is loads of small scale detail to see.

Here is another variation but with more OIII there is parts of both pictures I like I might try to combine them both

Whoops here is the picture

A nice new perspective on this old friend. Rather exciting!

Hi Olly thanks, its a work in progress and you are just the man I am looking for. ....

I intended on building a wide ish field setup this will consist of a Megrez 72 DGG with Atik 314L+ mono flter wheel and Edge 8 HD hyperstar with atik 314L+ colour and CLS filter.

But I thought I read somewhere something you wrote about aligning two scopes that they had to be paralific?? or something for the system to work?

Could you explain?

Can´t I just put one on top of the other?

[Gina]

My word! That's a beauty Wonderful

What Yves and I tried to do was add a 7 inch fast Maksutove parallel with this scope, a 14 inch ODK.

We wanted to use the smaller one to collect RGB while the big one did luminance and narrowband. The mount could handle it and the big scope got round stars but the Mak never did. We think this was because a significant physical separation between the scopes and/or a tiny misalignment between them requires a polar alignent precision which we weren't able to achieve and we gave up. It turns out that others have found the same thing. It is easy to make two small scopes in parallel capture data together but two big ones seems to be a problem.

If you just want to use one scope or the other then none of this matters. You can piggyback the smaller scope, certainly.

Send me a PM if this isn't what you were asking.

Love all of them, the colors are mesmerizing.

Thanks Carl,

Yes Olly thats what I was asking thank you.
