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.Continue reading “Galaxy M81 with iTelescope T5”
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.Continue reading “M101 and Surroundings with ASTRA by Susy Ghia”
Photo taken with iTelescope.net T5 in New Mexico, a reflector 0.25m f/3.4 and camera CCD SBIG ST-10XME. It’s the composition of 3 images with exposition of 120 seconds per light frame.
As usual I processed the images with IRIS and Lightroom CC to make it prettier.
To analyze the photo I used Astrometrica for data calibration, than APT to extract an object list and with Aladin, TOPCATA and CDS Portal website I tried to find some interesting objects around the galaxy.
NGC6543 or Cat’s Eye Nebula, it’s the composition of 3 x 60 seconds Luminance + 60 seconds exposition in H-alpha taken with iTelescope.net T24 – 0.61m f/6.5 reflector and CCD SBIG ST-10XME.Continue reading “The Eye of the Cat’s Eye Nebula with a Big Telescope”
I took this photo with a 250mm f/3.4 reflector and CCD SBIG ST-10XME using the remote telescope iTelescope.NET.
Is the composition of 4 images at 120 seconds of exposition and 10 images at 60 seconds of exposition all with clear filter, it has been processed with IRIS, Lightroom CC, than I made data reduction with Astrometrica and APT and than analyzed with Aladin and TOPCAT.Continue reading “Sunflower Galaxy – M63 and Surroundings”
Photo by Susy Ghia with ASTRA Remote Telescope #4 with SBIG ST-8300 CCD.
The photo has been processed with IRIS for registration and stacking than edited with Lightroom CC to make it a little prettier.Continue reading “NGC4631 and Surroundings with ASTRA Telescope by Susy Ghia”
The images have been shot by Susy Ghia using ASTRA Remote Telescope #4, a refractor 90mm f/4.5 with SBIG ST-8300M.
This is the result of four images for a total exposure of 35 minutes, I used IRIS for registering and stacking the images, also I applied the Asinh filter to stretch the image to increase the details, than with Lightroom CC I increased the sharpness and reduced the noise a little bit to make it pretty.Continue reading “M100 with ASTRA Remote Telescope by Susy Ghia”
M82 shot by Susy Ghia with ASTRA remote telescope on March 18, 2020.
The telescope used is a Newton 800mm f/5.
The final photo is the combination of three images in Luminance for a total exposure of 180 seconds, combined with RGB channels. Three images have been used per channel for a total exposure of 180 seconds.Continue reading “M82 and sorrounding by Susy Ghia with ASTRA remote telescope”
Five images shot by Susy Ghia using ASTRA remote telescope #2 on March 17, 2020. The telescope is a Newton 800mm f/5, and the images have been registered and stacked with Astrometrica with final edit in Lightroom CC.
Another series of images of Susy Ghia framing M106 and many others interesting objects around it, using ASTRA remote telescope #4 on March 11, 2020.
The final image is the processing of four light frames for a total of 15 minutes of exposure, I used IRIS for stacking, normalization and partly clean the gradient, than I created a flat frame from the light frame with paint.net and removed the dust and the ramaining gradient. With Astrometrica I did the data calibration than with Aperture Photometry Tool I extracted the list of stars and other sources.Continue reading “M106 and surroundings by Susy Ghia with ASTRA Telescope”
