NGC 2244 from Mark's

[Fay]

I did not want to do ha of Rosette again, and had intended to do OIII. trouble was, I cannot bring it into focus using the QSI/Leitz.

I could have gone elsewhere, but as the sky was so good & there were so many stars, i was not sure i was on my alignment star as they are so small using the lens as usual, & had to hunt for the Rosette. i did not want to spend any more time looking for a subject when alignment could be wrong.

9x900 QSI/Leitz, 7nm ha

[Rocket Pooch]

It needs O3 and S2, then its a proper image good though....

[Fay]

I will have to do OIII with another method & combine

[JohnP]

lovely widefield Fay... John

[Fay]

thanks John, not as intended, but will blaze on!

[The Thing]

That is very nice Fay. You must get your filters sorted for this combination as based on this the results will be superb.

[RobertM]

I know what you mean Fay but you have to agree that it's come out very well !  What are you young to do about the Sulphur and Oxygen - it would be nice to be able to add those.

Robert

[Fay]

well i will setup the QSI with the ZS66, for OIII, possibly Sulphur

[MarkS]

That is stunning Fay! 
So much contrast and faint wispy stuff.
You must be well pleased.

Mark

[Fay]

Yes, thanks Mark, will have to sort colour out, hopefully

[RobertM]

Fay, are your NB filters not parfocal or nearly so ?

[Fay]

Well the ha is Baader & the rest Astronomik.  All will be ok with other setups & another lens, but with the Leitz, even with ha, inifinity is the focus point, no room to spare, scrapes through by the skin of its teeth.

[RobertM]

The bandwidth difference of the filters might cause a problem if you did a NB palette.  The Baader is 7nm, are the Astronomiks 12nm ?  If that's the case then the wider bandwidth will cause larger stars.

[Fay]

Yes I have a full set of 12nm Astronomik.  so the Astronomik OIII is 12nm? probably

[PhilB]

Nice image, Fay. Lovely wide field too.

[Whitters]

One of my favourite objects, lovely image Fay.
