A twin quasar!?? gravitationally lensed ?!! Well… it seems to be a good excuse for imaging the field…
20mnn exposure (L:4x300s)
Acquired on the 17th of March 2020 with 8″ ONTC
Setup: TS ONTC 200/800, 2″ Feathertouch, AZ-EQ6, QHY163m gain=100, OAG-M, QHYCFW2-M, AstroLink 4 mini. Software: APT, Stellarium, PHD2
This image is a quick capture part of a field already imaged in 2019 with Samyang 135mm lens. At this time, I was very surprised of detecting a quasar with a redshift of 3! Let’s see now what will be detected at 800mm of focal…
5h exposure (Ha:30x600s)
Acquired from the 30th to the 31st of December 2019 with Samyang 135mm
From 09:56 pm to 04:22 am GMT+1
Setup: Samyang 135mm F/2, AZ-EQ6, QHY163m gain=100, QHYCFW2-M, AstroLink 4 mini, QHY5L2M. Software: APT, Stellarium scope, EQ MOD, PHD2
This image has mainly been acquired for future HOO/SHO mix. But the region is also located on the ecliptic plan giving some interest for looking at possible solar system objects. Let’s see if the Ha filter may have some influence on the detectivity of possible asteroids…
11h50 exposure (Ha/OIII/SII:4h50/3h30/3h30 sub:300s)
Acquired on 3 nights of 2019 (08/25, 09/04 and 09/12)

This is an another famous target, very bright and very high in the summer sky: the North America nebula also named NGC7000. And this nebula is not alone on this image…
2h30 exposure (Ha/OIII/SII):3x10x300s)
Acquired on 3 nights of 2019 (08/25, 09/04 and 09/12)

Summer gives the opportunity to capture wide nebula in narrowband. The result is generally colorful but can also led to excess. Let me know what you prefer with these M8 (Lagoon) and M20 (Trifid) nebulas! HOO or SHO?

After a 1st attempt on TrES2-b, here is TrES1-b transit with the aim to capture all the transit and obtain more accurate data!
