IC4628 Prawn Nebula

[CoolhandJo]

IC4628 Prawn Nebula is not easy to image. Its a bit faint and by nature "misty". This is 139 x 4min through L-Extreme, plus 21 x 4min L-Pro for stars. Total 11 hours.
Pixinsight processing. ED72 on Star Adventurer Pro . Guided. Asi533mcpro

Impressive depth on this Paul.
The extremities you've picked up are very faint.

Nicely done Paul. That one's hard in RGB. :thumbsup:

[CoolhandJo]

Thanks Kanga - 8 hours my absolute minimum now - anything less and the Bayer matrix kills it!! lol

[CoolhandJo]

Thanks Pete! I scanned images of this target in advance. Your spot on - the outer whispers are almost non existent in most images :)

[CoolhandJo]

Thanks Marc! first image that I used L-Pro for RGB stars. TBH the RGB version itself was rubbish! This target simply too faint even for Bortle 5 and L-Pro. But used for stars and merged - all ok!

Paul, that's a great capture especially by ED72 & Star Adventurer!

Nice work Paul. A good result with plenty of detail.

[CoolhandJo]

Thanks Sean. I did a firmware upgrade way back and the tracker went from huge errors every 15min to no huge errors at all? So I tried 10min sub and got round stars with ED72. Go figure :shrug:

[CoolhandJo]

Thanks Rodney. going to try and milk this set up for all its worth! :lol::rofl:

Very nice work Paul 👍

[CoolhandJo]

Thanks Andy! Multiple nights means inevitable cropping but I try and spend time getting it as close as possible to the previous nights session

[CoolhandJo]

Thanks Matthew

[Nikolas]

Paul has this been cropped? thats quite a bit of detail from the 72

[CoolhandJo]

Hi Nik... yes took a bit off on the right hand side. My mount has no Dec motor so dithering moves the target one way. Lol. Yes the ED72 needs perfect focus. But once achieved works well with the asi 533 and the SW reducer.

I'm gonna get the zwo focuser for the ed72 as well I already have it on my 130 and it makes a massive difference.
