Barred spiral galaxy located in the constellation Andromeda, distant about 40 million light years from Earth.
NGC 7640 in Andromeda
Messier 5 with ASTRA Telescope
Messier 5 is a globular cluster in the constellation Serpens distant from Earth 25000 light years.
This is the processed image from the sequence of images shot by Susy Ghia using the 150mm f/5.35 refractor, part of the network of ASTRA remote telescope in Castiglione del Lago, Italy.

After the NGC 4945 I came back to M63 the Sunflower Galaxy, is a spiral galaxy in the northern constellation of Canes Venatici. I made the RGB version using the beautiful photo from Dean Jacobsen’s Astrophotography website.

The image is the composition of 4 x 120 seconds exposure in Clear filter from the iTelescope.net T17 at Siding Spring Observatory in Australia, 432mm f/6.7 reflector and CCD FLI ProLine PL4710. I used also two images from ESO website in order to add colors to the image.

The galaxy NGC 4565 in Coma Berenices, is the composition of 6 x 120 seconds in R channel + 6 x 120 seconds in B channel, the G channel has been synthesized with IRIS.
The images have been processed with IRIS and Lightroom CC, then I used Astrometrica for data reduction and APT to extract a source list. The result has been analyzed with Topcat, Aladin and CDS Portal website.

Not at the center as I hoped but still made my day, I took this photo with iTelescope T17, a really big reflector, 432mm f/6.7 and a CCD with high QE.
Continue reading “NGC 4945 Almost Perfect Shot…”Galaxy M81 with iTelescope T5
Composition of 6 images at 120 seconds of exposition per image in R channel, I used the iTelescope T5 in Mexico, a 0.25m f/3.4 reflector with SBIG ST-10XME CCD.
I used IRIS for registration and stacking, and a little bit of Lightroom CC to make the final photo a little more pleasant, the raw images have been calibrated using MaximDl by iTelescope.

The raw images have been shot by Susy Ghia with ASTRA remote telescope, a 90cm f/4.5 reflector with camera SBIG ST-8300M.
The processed image is the composition of 2 frames with exposition of 900 seconds per frame. I used IRIS for registration and stacking, then I used Lightroom CC to stretch the levels and make it more pleasant to look at. I did data reduction using Astrometrica and APT to extract a source list, then I analyzed the luminance frame using TOPCAT and Aladin.
