The Leo Triplet consists of the galaxies M66, M65, and NGC 3268 and this may be the best I can do given my equipment and the amount of light pollution that I have at my observing site (my front driveway). NGC 3628 (furthest to the left) is showing a hint of dust lanes (it's seen nearly on edge) while M66 (lower of the three) is showing some asymmetry in its nearly face-on spiral structure. You can also refer to the image notes to identify each of the galaxies.

The galaxies in the Leo Triplet may be about 35 million light years away which means that they are about fourteen times as distant as the Andromeda Galaxy ((M31).

Leo Triplet, View On Black

Photographed on January 19, 2012 between the hours of 1:22AM and 2:15AM PST from a significantly light-polluted, near-center-city location using an unmodified Nikon D5100 DSLR (ISO 1600, 10 seconds x 124 or twenty minutes and forty seconds total exposure integration time) and an unfiltered 105mm AI-S 1:2.5 Nikkor telephoto lens set to aperture f/2.8. Image stack created with DeepSkyStacker (124 "light" frames and 124 "dark" frames) with final adjustments done in Photoshop CS3.

Camera guiding was done using a hand-driven, barn-door type tracking mount (two boards, a hinge, and a screw you turn by hand).

I had another Comet Catalina search this morning. This comet is only just visible on this DeepSkyStacker image made from 39 stacked 1 sec, exposure maximum ISO; f4.5 using a Canon EOS 60D with no tracking. I have also included magnitude values of some of the Virgo objects that are in the frame (values courtesy of Stellarium). I was hoping this comet would show a bit brighter based on the expected magnitude.

Notes: Spike on Upperleft cornet due to OAG prism

I reworked the source files from this image and did a 2x drizzle with a crop in DSS. You can see more about this object at Wikipedia.

Note how the upper right area has some problems with alignment. This was because I wasn't aware of how important doing the drift alignment with all the equipment attached can be. Over the course of the series of exposures, there was field rotation and this appears as blurred stars. Remember, this is a half-size crop of the APS-C sensor. Imagine what it would be like with a Full Frame sensor! Also, the drizzle option seems to have added some strange "rings" around some of the brighter stars.

This is about 1 hour of lights with a ton of darks that have been accumulated over time.

I did a gradient subtraction, histogram stretching, and curves. I didn't see the need to do noise reduction as the image looks pretty good to me at the moment. PP with PixInsight LE.

Essa é a região do Cruzeiro do Sul e nebulosa Eta Carinae. É possível ver na imagem além desses, a nebulosa do saco de carvão, próxima ao cruzeiro do sul (tem esse nome devido sua densidade de poeira não permitir a passagem de luz das estrelas que estão atrás), nebulosa da galinha correndo (bem ao centro) e outras, além de vários aglomerados estelares. Tratei esta foto pelo menos 3 vezes antes de chegar em um resultado que gostasse. É uma região difícil por ser muito estrelada, sendo difícil destacar detalhes. Espero que gostem do resultado. Foto tirada no @bregildo_camping , bortle 3.

This is the Crux and Eta Carinae nebula region. In the picture, we can also see the Coalsack Nebula (it has this name because of its gas and dust density, that keeps us from seeing the stars behind it), running chiken nebula (right in the center) and others, and also many star clusters. I processed this image at least three times before get in something that I like. It's a chalenging region because it has many bright stars, so it's difficult to highlight the details. I hope you liked. Picture taken in @bregildo_camping , bortle 3.

26x 30 second exposures (I shot 42 exposures but the rest were too poor to use due to vibrations in the telescope mount), shot between 10:26pm and 11:36pm, stacked so that the comet, which moves noticeably by the minute is held still in the final image.

- Using the Kappa-Sigma method which removed the stars except for some faint star trail remnants.

7.5inch Maksutov Newtonian telescope F5.3, 1000mm. ISO6400 .. so there's lots of noise in the exposures. I currently have to use a 1.6x barlow lens in the telescope in order to use the camera, until I get the right adapter for this scope. With the barlow, and the camera's crop factor, I was really shooting at F13.5 / 2560mm, so the view is more narrow and dark that it should be. 13 minutes total exposure time.

This image really only shows the core of the comet, the glowing ball of gas and dust around the comet extends out past all the edges of this image.

Comet 103P Hartley is a periodic comet that returns every 6.5 years. It might become visible by eye in October. On this night it had a magnitude of 7.6 and was in the constellation of Casseopia

Almost 4 hours of inegration, It barely fits on the frame because I didn't check properly the correct rotation at the time of shooting. Very happy with the result anyway, 100% I will shoot agiain next year.

Here's what can be done in the suburbs of Houston next to Ellington AFB on a overcast night with a Canon 50d and a Canon 70-200 IS f2.8 @ 15 exposures and a tripod.

I was going to try to capture Jupiter, but it was overcast in Jupiter's direction... So I pointed at the only object that I could see in the East Sky with the naked eye. I took 15 x 2 second exposures at ISO 12800 f2.8 and processed them in DeepSkyStacker and Lightroom2.

WOW! The Canon 50D rocks even in the hands of a first time astrophotographer! I never new a dSLR could see soo many stars on a hazy night in the city!

Bonus! I appear to have got lucky and picked up a satellite!

After looking closer, make that 8-10 satellites! Lots of space junk up there these days!

Bumped up the star detection threshold to 50%, and it looks more believable.
