Last Friday,18th September 2009, I got a chance to use the Equinox 120ED and Imaging Source DBK21 and DMK41 in the field. The sky condition was exceptionally good. I went to Pak Tam Chung at about 10:00pm after monitoring my daughter’s homework. Since I got lot of outstanding tasks, time was limited for me. I planned to image the Jupiter and one to two deep sky objects, but I end up with the Jupiter only. The main reason was that I was inexperience in handling the Imaging Source camera. I’ve learnt the basic of how to image Jupiter from David, but lack practice. This was the first time I use the DBK to image Jupiter. I knew some crucial parameter in imaging the Jupiter. However mirror setting could ruin the photo! It takes time to learn and art cannot be rushed!
When I arrived PTC, I started the setting at once. I was kind of slow and inexperience in setting up the equipments. Since this telescope was a rare species in PTC, It attracted some stargazers. Finally when the setting was done, we viewed Jupiter. Everyone was amazed by the 120ED. Mirror God used his, prestigious telescope tester, Takahashi 3.6mm eyepiece, to test the Equinox 120ED. Here was his exact wording:
This was not the end of the story. When I finished the setup of DBK 21, the movie shocked everyone. It was because I was green in setting the DBK, everyone knew it when they saw my clumsy acts, but the movie was quite sharp already before stacking. It was good because the seeing & transparency were good. These unleashed the power of Equinox' optics and the power of DBK's electronics. My comment is that Equinox 120ED delivers high contrast, high color saturation and high resolution images in its own class. The color was a bit warm and yellowish in viewing Jupiter. The price is good. No complain for such performance price ratio, $13800 for a 120ED! If one wants to take serious photos, a Feather Touch focuser is needed, perhaps a high quality reducer. I am still very busy on school’s work and no time to learn how to stack the photos. The photo below is just a default click-click-click output of Registax 5.0. I will process it seriously later.
