DSO 遺照集 -- NGC7000
Re: DSO 遺照集 -- Horse head from PTC with ED80Sf
49. Horse head
Taken with Vixen ED80Sf + reducer + LPS + 40Da @PTC in 2014 @510mm F6.4
24x240s @iso1600, autoguided with Vixen GP2 photoguider in RA direction only

Re: DSO 遺照集 -- Orion taken in Lantau
50. Orion
Taken with Vixen VSD100 + LPS + 5Da at Pak Kung Au in 2015 @380mm F3.8
23x180s @iso800, autoguided with Vixen GP2 photoguider in RA direction only
Calibrated with darks only in DSS
If calibration with a good flat, the result could be improved quite much I think. However, no chance to take flats with this setup anymore.

Re: DSO 遺照集 -- M42 taken with 30cm Newtonian
51. M42 taken with 30cm newtonian
30cm F4 Newtonian + TV paracorr + LPS + 100Da @PTC in 2015 @ 1380mm F4.6
10x240s @iso800, autoguided with Vixen AXD mount
Calibrated with darks only in DSS
Wish having a chance to shoot it again with a FF cooled cmos camera but the chance is very slim due to the price of a FF cooled cmos camera is too expensive to me.

Re: DSO 遺照集 -- Horse head taken with 8cm triplet
52. Horse head with 8cm refractor
5x210s @iso800, autoguided
Taiwan brand 8cm F6 triplet + flattener + 350Da @visitor centre in TMS in 2009 @480mm F6
No darks, bias and flats calibrated in DSS
A suprise to that result due to total exposure is just 12.5 min and it was taken at TMS where the light pollution is very severe.

Re: DSO 遺照集 -- Best M27 taken ever with DSLR
53. M27 with 30cm Newtonian
60x30s @iso800, unguided with Vixen AXD mount
Taken with 33cm F4.5 Newtonian + TV paracorr + LPS + 100Da @YL in 2015 @1720mm F5.2
Calibrated with darks only in DSS
This one should be the best image taken with DSLRs ever up to now.

Re: DSO 遺照集 -- M42 HDR
54. M42 HDR
Another try on practising HDR in PS. Most of the photographic data had been forgotten.
Taken with Vixen AX103S astrograph + LPS + 300Da in 2009 @824mm F8
2x300s + 7x30s @iso800, autoguided
Just doing HDR with 30s subs, the result seemed a bit weired.
