20. M13 from TMS with ED115S apo refractor
(Last image of Leo Triplet is a repeated image posted in this Album, and so it is not counted.)
Taken with Vixen ED115S apo + 300Da from TMS in 2009 @885mm F7.7
22x120s @iso400, autoguided with SXD
Half moon high in the sky
Though very barely, the IC is still there. Wish one day I could use a 13cm or even 15cm apo to take DSOs in HK.

22. Double Clusters
Taken with Vixen ED70SS + flattener + 300Da from TMS in 2011 @400mm F5.6

Stars elongated a little bit, and so RAW data will be deleted after posting.

23. Rosette
Taken with Vixen ED80Sf + LPS + 40Da from PTC in 2014 @600mm F7.5
21x240s @iso1600, autoguided with Vixen GP2 photoguider in RA direction only.
RAW data seems not too bad in considering they were taken in HK, and so decision is not made yet to be gone or kept.
