Flame and Horshead Preview...

[Psychobilly]

Just a single frame caught early of the framing for the Flame & Horshead Nebula stack i'm working on later...I'm capturign subs until dawn on that oen ratehr than redoing M42/M43 at F6.3...I think it will be worth it

Got to work out where that reflection is coming from though

Excellent! Our modified DSLRs love the Flame nebula

Ok one for the experts...

Whats out of alignment in the system to cause the "reflection" of the primary ist it simply collimation (or lack of ) ? - I think this is also giving the impression of elongated stars on the samller ones...and I know the distance between the FR and the CCD is wrong

So here's a very disappointing stack - as well as the elongation the vignetting was horrendous and has been very crudely "fixed"

If I can get the issues sorted i think the general framing for the FOV is about right ....

Help Please

On that note...time for a few hours ugly sleep before breakfast....

Say what you want; that flame nebula is just awsome!

Thanks Glenn,

I haven't been able to get to sleep because I am so disappointed with this shot... it's my own fault for trying to be a smartar53 with the Reducer/filter combo on the back of the scope (posted a thread in the imaging discussion section for advice).

If I can get the configuration right then the framing is almost exactly what I had in mind so the center Ra/DEC cor-ords and the camera rotation angle have been recorded for "posterity" (written on the wall of the obs in permenant marker)

Blimey, disappointed... You're a hard task master Billy, that's a belter of an image

[Psychobilly]

I wish I could agree John...

Oval Stars, artefacts and horrible vignetting :oops: ... I must do better :withstupid: :crybaby: :crybaby:

Hopefully I'll get the issues sorted pretty quickly though :shock: :x :scratch:

To my untrained eye, apart from that odd reflection you mentioned... But hey, what do I know . I'm sure you'll sort it quickly

[Psychobilly]

I suppose I could use some "creative" license....

BIAB....with the result...

I think it's pretty good Billy - it a tough target with a bright neb and a faint neb in the same shot - as well as a very bright star just to top it off.

[Doc]

It's a very pretty image Billy.

But I can also see the oval stars but you do have to look pretty close.

I'm not an expert so can't help I'm sorry to say.

[Psychobilly]

Thanks all...

Oh and I am not paying taff to "refresh" all my images - he's just recently come over from the "other place" and is playing catch up
