The big Eta

[Peter Ward]

Hummm.. rain.

Looked at what RHA Eta data I had....and stitched it into a mosaic.

This thing could get bigger than Ben Hur.....but decided HD format was good enough for now.

The mosaic link is here

Awesome Peter.

Have you got a higher res version ? I have a big monitor so this only fills 70% of it.

Just for you Chris...now 2500 pixels wide. (I would have made it bigger but the 10 minute section is a little noisy)

wow its huge. I love the intense middle part with it thick bright parts then the left hand side of the image where the clouds swirl around thinning out with the black parts visible. I really need to learn the correct terminology great image

Is this a single Sub Peter or is this a stack? If so what is the sub duration. Very flat image, looks pretty nice.

Top left is two 10 minute subs, bottom right two 5 minute subs (two panel mosaic).

The images were taken a few nights apart, but I'll be resequencing the mosaic keeping only the top left data.

As for the weather...or is it whether? I'm sure the mid evening Sydney news will have something to say about that !

A great looking photo Peter.

You guys are making Eta C the test target for new telescopes.

I am really liking the pinpoint stars, edge to edge here Peter, particularly with the STX.

I assume you will be able to get to focus with the STX FW?

I am so glad I am on the list for this (since 2009). I will not hesitate to sell my flourite FSQ106 when I get the email that mine is ready to ship.

Cant wait.

Great result Peter.

You're a brave man starting a mosaic project in this weather Peter - hats off. Should be a stunner when you finish! Early days I know but I like your treatment of the dynamic range. And those stars look tighter than a gnat's a^^e ... but will reserve final judgement on that till you post even a portion of it at 100%!

Thanks Martin....I think I may have trumped you by a decade on the RHA
(mine was swapped from May 1999 and for a different scope I suspect Roland will never deliver )

All I needed was a custom adapter (precise parts) for the STX/FWX combo. Works a treat.

The AP-RHA has simply no vices...and sublime 5 micron stars across the entire field...I'm glad to hear you are "on the list"

Ross.

Just sticking with "the program"

Sorry... my private joke...I knew Eta C was imaged often enough to call it a "standard candle" hence others could compare images they may already have captured as a benchmark

Tell me about it! Thanks, yes , not-likely

I really do appreciate your input Marcus... many simply don't appreciate the
sealing abilities of gnat's sphincters
