Can we spot nebulae in another galaxy? Yes, with the use of Ha filters we can detect those star forming regions in our neighbour galaxies.The Triangulum galaxy, M33, is located in the northern constellation Triangulum. As seen from Earth it has a really wide angular size thanks to its proximity to our Milky Way. M33 is over 50,000 light-years in diameter, and it's located some 3 million light-years away from the Solar System, third largest in our Local Group of galaxies after M31 and the Milky Way.If we inspect the image closely we can see tens of small blue clusters of stars. The pinkish regions are shown thanks to the use of a Ha filter that captures the emission data from these HII active star forming regions. The most apparent of those regions is NGC 604, the brightest in this galaxy (bottom left of the image).To capture this colorful image I used my dual Takahashi setup. I gathered data from both FSQ's (FSQ85 and FSQ106). The Luminance data was captured with both telescopes while the Ha and RGB data was captured with the FSQ85.Thanks for your time on this website.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
