命運難逃 --- Rosette in BW
命運難逃 --- Rosette in BW
塵歸塵,土歸土,折射鏡派終歸走回折射鏡懷抱。
個人偏見,除細CO牛鏡外,目視月球,味道 + 立體感,無鏡能及折射鏡。
個人偏好,折射鏡拍深空的味道確不同。
個人偏激,香港這樣地獄的夜空,用折射鏡拍最合適。
於是,重回 SXD2 + SD115S 的下隊伍中。
若然有錢,TOA130 更好,可惜 Vixen 沒有SD130S。
若然有臂力, TOA150 更優。

Re: 命運難逃_1st light
Last night was clear though transparency was not very high in YL. So gave my new set up a test after gathering with my friend. Light pollution is really very heavy at my mother's living place, and so no other good choice except M42 again.
Taken with Vixen SD115S + HD reducer + LPS + 100Da in YL @700mm F6.1
27x90s @iso1600, autoguided with Vixen SXD2 mount
Stacked and processed in PI with 9 darks and 9 flats calibrated
Final touch in PS
SN ratio is very low and have done my best effort already.

Re: 命運難逃_New moon
Tried to shoot the new moon and Venus together on a single frame with SD115S + reducer but failed. The focal length of 700mm is still too long to capture them on a frame together and seems 500mm is the best. So, changed to shoot the new moon at native focal length of 885mm. Unfortunately, the air was very unsteady.
Taken with SD115S + M6 in YL yesterday evening @885mm F7.7
Final touch in PS after wavelet in Registax 5.0

Re: 命運難逃 --- M15
This GC was going down to west horizon when back my observation site after dinner. The most unfortunately, clouds then kept coming from SE when I started the imaging. So had to stop imaging after taking 22 frames.
Taken with SD115S + 462C in YL last night @885mm F7.7
22x25s, autoguided with SXD2 mount
Stacked in DSS without any calibration
Processed in PI
Final touch in PS
Seeing was very bad last night.

Re: 命運難逃 --- Eye of the God
Just tried to see how deep it could go in Ha if that Helix was exposed for 10 min @F6.1 with this apo SD115S at my observation site in YL. But seemed I had missed the best month to shoot this Eye of the God. The pic below shows how low the scope was pointing to when the last light frame was captured. Moreover, more and more LED lights were around my site.
Taken with Vixen SD115S + HD reducer kit + 1600MM in YL in HK last week @ ~700mm F6.1
9x600s in HA @7nm, autoguided with SXD2
Stacked and processed in PI with 3 darks calibrated only

Re: 命運難逃 --- M3
So as to have a best processing result on M3 and the tiny galaxy nearby, just do stacking of stars in PI with ignoring the stack on the comet. Seems the result not too bad, considering the total exposure is just 25 min in total merely. If weather and time allow, I will image M3 again with 1600MM cooled camera.
Taken with Vixen SD115S + HD reducer kit + LPS + 100Da in Sai Kung at the dawn of Dec 3rd @700mm F6.1
25 x 60s @iso1600, autoguided with Vixen SXD2 goto mount
Stacked and processed in PI with darks and flats calibrated
