Horsehead (New rig test 2)

[Guest Kheldar]

I didn't actually set out to capture anything on Saturday night, but peer pressure has won over and here's the results of what I got.

 

4x600s Ha - it's noisy, but I've got an interference problem i think as each individual sub is speckled with strange noise ... going to have to break that loom down

 

I've also got an EXPLETIVE Maxim/SX problem but I'm investigating that with the Yahoo group so hopefully a solution will present itself. Crashing randomly is not my idea of a good imaging session

 

Also have a nice halo on Alnitak - any experts I'd welcome your opinion on whether that's acceptable / expected from a Baader 8nm filter?

 

Quick process, so if you want to play the FIT is here - https://www.dropbox.com/s/4qf0pc71ghxi77t/horsehead.fit?m

In case that doesn't work for you, I've uploaded a TIF too - https://www.dropbox.com/s/10c3ljkfyszg40q/horsehead.tif?m

Very nice Stephen, well done! Love the ethereal look of this-fantastic

[Sheila]

Bit spooky really, but the horse looks good

[Doc]

The scope is doing the job it was designed for and a great job to.

[Tweedledee]

In mono it does look ethereal, and has a very different look to the full colour processed ones we have been used to.

 

It takes me back to some of the photos I used to be fascinated with as a child. They all used to be black and white back then, hundreds of years ago . It actually looks like it has come out of something like the old Flammarion Book of Astronomy on a plate from the 100" Mount Wilson telescope.

 

Very nice and different.

[Guest Jason]

Yep like this one aswell.

[oldfruit]

I really like it, the Horsehead and the Flame have both come out really well. Even with the issues that you have mentioned, it`s a lovely pic.

That is a bit surreal Stephen.

Almost ghostly in appearance.

I do like that.  

[philjay]

Excellent, tons of data and great detail in the horse and curtain nebulosity.I see the reason for your 1st explative last night, the flame is superb

[Guest Eddy]

Wow, incredible Stephen, nice one

Nice capture.

Could the Halo round Alnitak be caused by internal reflections?

The Halo isn't concentric either so could the ccd be off square?

Why did I just know you would flip it round How did you calm Alnitak down?

I'm not convinced it's a reflection, but I stand to be proved wrong - I think it's just a halo as a result of using the NB filter / Alnitak being soooo bright!

As to the off square, it's a definite possibility as I've not collimated the new scope / adapter  / focuser yet, I really need to get round to doing that

[+Ibbo]

layer mask,still not calmed it so sledgehammer tactic lasso tool and min filter

 

 

and it just had to be flipped

My astronomic type 2 ha filter gives the same type of halos even though they (astronomik) kindly swapped for a non halo filter. Ive come to the conclusion its a by product of the ha plus my lp filter. The halos are also non concentric even though i have checked collimation on my flt 98 and feathertouch focuser / imaging train

Cheers Phil, I'm still going to ask for a replacement I think, and will check the collimation. If it comes out no better after both of those, then that's just the way it's meant to be

 

PS SGL project IC405 - it's the Flaming Star Nebula we couldn't remember

[T A WOW]

That is a very nice image. Hope you get your interference issues sorted soon.

A quick play with your data. I didn't try to control Altinak or whatever it's called, just left it alone. The halo looks a bit harsh edged to be able to layer mask it.
