Re: DSO 遺照集 -- M106 wide field

文章 LT » 週四 02 7月, 2020 20:00

82. M106 wide field

Taken with Vixen VSD100F3.8 + Atik 383L mono cooled CCD @PTC in 2015 @380mm F3.8
LRGB = 20x240 s: R=G=B=5x120s @binning 2x2, autoguided with Vixen SX2 mount
Stacked in DSS with darks and bias calibrated

Very unfortunately, when combining LRGB in PI, one bright star failed to the job.

Re: DSO 遺照集 -- M45 taken with cooled CCD

83. M45 taken with cooled CCD

Vixen VSD100F3.8 + LPS + Atik 383L mono cooled CCD @PTC in 2015 @380mm F3.8
LRGB = 6x360s : 2x360s : 2x360s : 6x480s, autoguided with Vixen SX2 mount
Stacked in DSS with darks and bias calibrated
Processed in PI and PS

R channel is a bit out of focus, and so it results stars look like there are red halo aroound them. If still having the passion on astrophotography, maybe I can obtain a better result with my 6" F4 Newtonian + 1600MM by the end of this year.

Re: DSO 遺照集 -- M42 taken with cooled CCD

文章 LT » 週一 06 7月, 2020 23:34

84. M42 taken with cooled CCD

Vixen R200SS + MPCCIII + LPS + Atik 383L mono cooled CCD @PTC in 2015 @800mm F4
R=G=B=3x240s @binning 2x2, autoguided with Vixen SX2 mount
Stacked in DSS with bias calibrated only
Processed in PI and PS

Now, have known more tricks on imaging with CCD in Hong Kong, and so by the end of this year I think I can achieve a much better RGB image with my 6" F4 newtonian.

Re: DSO 遺照集 -- Leo Triplet taken with cooled CCD

85. Leo Triplet taken with cooled CCD

Taken with Vixen R200SS + MPCCIII + Atik 383L mono cooled CCD @PTC in 2017 @800mm F4
R=G=B=4x240s @binning 2x2, autoguided with Vixen SX2 mount
Stacked in DSS with bias calibrated only
Processed in PI and PS

Why no dark was calibrated? It is because the sensor temperature has no record.
