Total integration time: 6 3/4 hours

 

Thanks for looking!

Adam.

That's one of the best I've seen! Lots of detail in the darker dusty stuff!

Stunning mate.......

That is magnificent. That's one of the best I've ever seen too.

You have used two quite different scopes haven't you! Which images were obtained with each?

PS That Epsilon is one hell of a scope isn't it. Hell of a price too! I've just been looking at the specs on FLO.

APOTD.....

Very nice Adam, so how did you solve the EFW problem?

Thanks Carole.  It took three restarts of the PC but I was able to get the EFW I have connected and moved to Lum, then unplugged it before it crashed everything.  The RGB is from other data with my ED80s.  TBH I need to just buy that EFW3

Thank-you.  I used the ED80 for RGB and the epsilon for Lum.  I deciding whether to sell of the ED80s but they are super super scopes.

Appreciate the comment Dave, for under 3 hours luminance I was surprised myself.

It does look very light now that I'm on my PC monitor.  Could be just this screen.

You're getting some nice results and quickly too.

I agree a little light, looks like the luminance is overwhelming the rgb.

Love that dust!  Superb image.  You've muted the ha a fair bit which helps to reveal the dust but possibly a tad anaemic, this isn't a criticism just a reflection on processing options.  It's a brilliant piece of work.

[astro mick]

Exerllent as always Adam.

That's some interval between completion.

How good does that look... so much matter and detail... very nice.

Very nice.  I have a similat problem with my STT 8300--filter wheel jams periodically.  Often requires a dismount and manual unsyicking.  That of course ruins the fra ming and flats.  The ASI 1600 is only marginally better--the filter wheel does not set accurately enough to allow the use of flats for more than 1 use--as soon as there is a filter change, the flats are no longer good.  This is very irritating when you want to shoot more than 1 filter in a night.  The really irritating thing is sometimes when I do a meridian flip, the ASI 1600 fails and I have to turn it off and reboot maxim (and sometimes the computer)--which of course nullifys the flats.

Great image. The dust is structured and fluffy and you have captured nebulous structure right up to the edge of Alnitak which is something that sets the best renditions apart in my view.

Beautiful !

Thanks very much for the feedback.  I'm planning on adding some Ha to this.  I'm not sure if I can add more colour.  I will have to break down my kit to change the EFW, and I am not planning on keeping it in the same orientation in a bid to reduce the distance of the weight from the dec axis.

FWIW, i adjusted the curves to lower the brightness.

I like that the colour is *not* overpowering.  All personal taste.

Great depth.

Stunning image Adam

thanks for sharing, can I ask, how long are the individual subs? 
 

cheers

Thanks Bryan

The subs were all 300s, but this over exposed Alnitak.  The RGB was from an ED80, at F6.3, so a lot less exposed that the epsilon Lum at F2.8
