IC1805 aka the Heart Nebula is an emission nebula located in the constellation of Cassiopeia about 7500 light years away.
In the center of this image is a "knot" known as Melotte 15. I imaged this region using this telescope at F/7 resulting in a smaller FOV seen here: flic.kr/p/p8BWvp

I mount my Nikon lens and camera on top of my optical tube at the moment. There was a constant wind of ~5mph last night when I took my images. I did 33 light frames and used the best 90% for 30 frames. I polar aligned with SharpCap and began guiding. The graph looked good so I started imaging. The stars seemed to stay in focus so I upped my exposure to 212 seconds and let it go to work. After stacking the files in DeepSkyStacker I pulled the TIFF file into Photoshop and mostly followed along to AstroBackyard's Rosette Nebula tutorial, making some of my own adjustments where they were needed. I'm still struggling with color of the surrounding stars. My WB was set to automatic, that might be why the color is a bit hard to manage. The Moon did rise while I was imaging and I can see a difference in my light frames, I'm sure I can do better and might try again during a new moon. But for my first time trying M101 and autoguiding I'm pretty happy!

E' incredibile ma vero. Avevo acquistato lo Schmidt-Cassegrain Celestron C8 (203mm f/10) nel 2000 e non lo avevo mai provato per la fotografia Deep-Sky. Neanche dopo aver acquistato il suo riduttore-correttore 0.63x, perchè non solo il suo campo corretto è più piccolo del formato APS-C ma ero anche convinto che la mia HEQ5-pro non fosse in grado di gestirne adeguatamente il peso e la guida. La ASI533MC-P, con il suo sensore da 1" (11.31x11.31mm) mi ha spinto a provare.
Ho iniziato con un target luminoso e quale migliore occasione che ripuntare la nebulosa M16?
Il controllo con la HEQ5 è al limite e alcune volte le oscillazioni per le folate di vento creano problemi. L'autoguida fa quello che può e la turbolenza spesso non mi ha aiutato.Forse un'ottica adattiva potrebbe fare miracoli, ma sono comunque rimasto piacevolmente sorpreso da questo primo rsultato ottenuto. Comunque c'è da dire che è stato un grande vantaggio per me avere sul tetto di casa "l'ossservatorio", che mi ha semplificato molto il processo di acquisizione, composto da 4 sessioni fotografiche.
I Pilastri della Creazione, la Guglia stellare, le nebulose oscure che si stagliano nel vasto tappeto di emissione Ha e i contorni delle nubi di idrogeno: questo spettacolo visto con una focale di 1260mm è stato veramente appagante.

___________________
It's incredible but true. I purchased the Celestron C8 Schmidt-Cassegrain (203mm f/10) in 2000 and had never tried it for deep-sky photography. Not even after purchasing its 0.63x reducer-corrector, because not only is its corrected field smaller than that of an APS-C format, but I was also convinced that my HEQ5-pro wouldn't be able to adequately handle its weight and guiding. The ASI533MC-P, with its 1" sensor (11.31x11.31mm), encouraged me to try.
I started with a bright target, and what better opportunity than to refocus on the M16 nebula?
Control with the HEQ5 is at its limits, and sometimes the oscillations caused by gusts of wind create problems. The autoguider does what it can, and the turbulence often didn't help. Perhaps adaptive optics could work miracles, but I was still pleasantly surprised by this first result. However, it must be said that it was a great advantage for me to have "the observatory" on the roof of my house, which greatly simplified the acquisition process, which consisted of 4 photographic sessions.
The Pillars of Creation, the Stellar Spire, the dark nebulae that stand out in the vast carpet of Ha emission and the outlines of hydrogen clouds: this spectacle seen with a focal length of 1260mm was truly rewarding.

Re edit one of my old post using what I learn last year, also taking advantage of Flickr new black background. Took this one with an inexpensive telescope and camera adapter. (Spanish: Una nueva edición de una de mis anteriores de la Luna, aplicando todo lo que aprendí el año pasado. Utilice solo un telescopio de principiantes y un adaptador de camara. El nuevo fondo negro de Flickr ayuda.)

Description
First light of my new mount Mesu 200 mk2 !!
Really happy when I compare with the same picture last year, under different skies and diferent mount....
NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820.
Open star cluster NGC 6823 is about 50 light years across and lies about 6000 light years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association. (Description credits: Wikipedia)

This is my first try at processing colour saturation of the moon.
Colours are amplified during processing. The colours represent various mineral and iron deposits found on the moon. Blue hues reveal titanium rich areas, orange and purple colours show regions relatively poor in titanium and iron.

Here is a wide-field view of the Trifid Nebula, Messier 20 (M20) and the open cluster Messier 21 (M21) in the upper left. The word trifid comes from the Latin word trifidus which means “divided or split into three parts or lobes”. From Wikipedia - The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance.

This was my second attempt last night on Venus before the clouds rolled in. This time I used a Powermate 2.5 with the QHY5III-290M.
I tried something different in processing and subtracted the UV from the LRGB. The original LRGB was nearly featureless. Still not the best result, but it's beats staring at these clouds. :)
