Uranus - who is who ?

I had no success to identify the moons. Erros of 1 minute cause much changing of position of moons. The time and hours seems to be precises: 25 Dez 2014 - 20:09:06

first photo: GSO 305 mm - Canon T3 - 1 x 120 sec - ISO 800 - Skyglow filter

second photo: 1 x 120 sec - ISO 800 (moons) - 1 sec - ISO 100 (planet) - 200 %

Good job Jorge; I've never tried imaging Uranus or Neptune, maybe I'll get to it one day.

wow, Andrew. I think you got identify them. I tried in CDC but I could not see that distribution. Perhaps because I was trying with the bodies more near to the planet. The image in CDC showed only up to Ariel. Titania, Umbriel and Oberon was out of the field.

Thank you for help !

What catalog are you using to identify the star UCAC4-472-001127 ? For me the Tycho2 doesn't show any star in that position.

Thank you, for coments.
Raymo, I always did planet with movie and ASI120MC or DSI or SPC. But I know that the resolution of my T3 and ASI is very similar, not equal. So, I was waiting for another target get good position to be shot, than I tried Uranus. And it is similar in view did by DSI-1 and barlow 2x. http://astronomia-e-astrofotos.10697...012-td472.html
Therefore I think that it is possible some planetary good photos with Canon 1100D.

A pleasure Jorge. That FOV covers about 2'15".

The star name tells you - UCAC4. Which version of CdC do you have and which catalogs have you loaded? Among others I have UCAC2, UCAC3, UCAC4 and NOMAD but normally only use UCAC4 for a small FOV and NOMAD for the smallest FOV, but today I had NOMAD turned off.

Jorge, there is a link to the pre-formatted UCAC4 catalogs on the CdC Downloads page. They are hosted at Sourceforge. There are various other catalogs there too.

If you want to use NOMAD you have to build the catalog. Instructions are here but it is a huge download using Bittorrent and then a lot of CPU. It's also probable the torrents aren't all online very often so it might take a while to get them all. My copy is about 30GB ready to use.

Apart from those I usually build my own, including a rebuild of the WDS every time they release a new version.

Urano 2015

Another try with Canon 350D. Now with barlow GSO EDO in 1.5x mode.
Terrible experience ! This barlow has much spherical distortion. It is very difficult to find a good focus. However, it was done !

GSO 305 mm - Canon 350D - Skyglow filter - Coma Corrector - Barlow 1.5x GSO EDO

first photo: 3 x 10 sec - ISO 1600

second photo: who is who

third photo and fourth photo: 1 sec - ISO 800

And last photo: How I find the resolution of my set.
