Here's my "November project" with the FSQ/STL11k...
In this image I first tried to put into practice a method to pull the dust out that I had been thinking these past few days, and I didn't end up too thrilled about the results. It induced some "blur/denoise-like" effects early in the processing, and it also fabricated bloated star halos in the mid-sized stars (Rigel was put where it belongs with a quick HDRWT).
So after the fact I went back and did some reprocessing from scratch treating large and small scale structures separately, then merged the results to the previous image. This helped me reduce some of the halos (I did't bother with the big ones because those are "optical presents" not the effect of bad processing), keep the stars under control, enhance the witch head a bit, etc. but didn't remove the denoise/blur effect on the background.
I still think the initial processing thingy may work, I just need to play with it a bit more and be more careful next time... Nevermind the halo aroud Rigel is purple, although that's how it came out.
The image is in fact a 2 pane mosaic with data from 3 frames, each taken from a different site, with a total exposure of almost 12 hours.
This image was selected as NASA's Astronomy Picture of the Day on
December 29th, 2009.

I have followed your work every since you joined TAC and I am amazed how technically proficient you are with complex imaging targets and techniques! Congrats, your work is inspirational to other imagers like myself.

Muy impresionante la calidad de la imagen. Recién compré un telescopio TASCO 114x900mm, estoy en 66°55'W 10°30'N(Caracas-Venezuela). Pregunto: ¿podré visualizar la forma de esta nebulosa cuando pase cerca del zenit? Soy principiante inexperto, pero sé centrar bien un Objetivo

Esta foto es muy original, no recuerdo haber visto una semejante en la FADD.
Aunque medio entiendo algunas cosas escritas en Inglés, adivino la descripción que haces de la foto.
Me gusta mucho por lo original.
Nuevamente te felicito, realmente me deleito viendo tu sitio DEEP Sky Colors.
Gracias Leonardo y Zoila!
Zoila cualquier pregunta que tengas sobre las fotos, no dejes de preguntar, bien aqui o en mi correo que ya conoces.

對於2009/11/16您所拍的星雲..我看見的是雲中有個精靈仙子（左邊那條星雲）促立在中間..她像是童話故事裡的精靈..有著明顯的身影〜而模糊的臉孔卻也戴著一頂與自由女神像相同的頭冠..張開著的雙手讓我覺得好想投入她的懷抱..而她那飄逸的長裙應該就是“女巫頭星雲“〜哈〜我喜歡！這張你拍的星雲圖比起那些很像人體內器官的星雲圖。美的太多太多了〜期待你美麗的作品再現〜祝福你〜

I say we change APOD to DSCpod..."deepskycolors picture of the day" because pretty soon you will be featured every day!
Your work is an inspiration... would love to see some processing tutorials by you.
Kind regards from The Netherlands,
Wouter Verhesen

Great work Rogelio. Congrats on your APOD. I really liked the framing with Rigel and the background stars.
zoila miranda (Contact, Page), December 30th, 2009, 8:51
Hola Rogelio, qué alegría me da esta nueva APOD, tuya!!!!.
Fíjate me encanta que la publiquen pues ya viste que desde que la ví me encantó y hasta hice la crítica que nunca había visto una foto ni parecida!!!.
Bueno me encanta verificar que tengo buen ojo para catalagar fotos APOD.
Nuevamente mil felicitaciones ahora y que el próximo año 2010, tambien sea un año en el que cada mes veamos una APOD tuya.
