NGC3372

[MeyGray3833]

Not sure if this is really worthy, I was very surprised at how clean the data was for 47minutes total doing a focusing/dithering/guiding/sequencing test in SGP 3. It still lacks some focus which I should be able to correct this week or next as I will have the right flattener for the scope. The only downside is it will also be a reducer as I cannot make the minimum distance for the other scope specific flattener that I have that offers no reduction.

Anyway, here it is, NGC3372 Eta Carinae in LRGB.

Cheers and clears.

'Worthy'? I don't really know this object well (being a n-hemispherite), but, considering it was only a test of some 47 mins of data, I would be far from unhappy if the result were mine.

Lovely! What camera ?

All the picture specs are in OP's link: QHY9 Mono @ -20c

Thanks for stopping in to have a look. 

Yes, QHY9 camera @ -20C. The QHY9 has the Kodak 8300 sensor. It has been a good camera.

Cheers.

Thanks! But I rarely click on links unfortunately!

Hi tooth_dr,

I appreciate you dropping in and taking a look anyway.

The reason I use a link is I try to keep all my images in one place that I can protect if I think I need to. I realise it is extra bandwidth and clicking for some, for which I'm very sorry.

Cheers.

Looks good--though its hard to look at it at this scale.  For some reason I can only open a tiny thumbnail.  Certainly has color.  Can't tell about focus.

More than "worthy"... Something to be proud of...

Don't worry too much about the flattener being also a reducer, the amount of detail captured through a reducer will be very close, if not the same, as when comparing to the full focal length image.

The reducer has a added bonus of having a wider field of view, guiding (or seeing conditions) are more forgiving, and you'll capture the same amount of signal in half the time.

Hi Rodd,

Are you clicking on the link above the image? That should take you to a full size image.

If not, I'll re-link it.

Cheers.

Thanks for the confidence boost on the reducer/flattener, I appreciate that.

It will take it from F7 to F5.6 which still should be OK considering the aperture.

I got all hung up on 2032mm imaging, but I'm starting to think that using the f6.3 reducer will give me the same detail when cropped to same framing.

At higher magnifications, images are more susceptible to seeing... or in other words, seeing imperfections are magnified too.

After I've finished my current imaging project, I'll switch to imaging with the reducer and compare to confirm my theory.

Interested in your results! Post them up when you have them.
