M27, the dumbbell nebula, thank you dtto. ron brecher
m27 is a classic example of a “planetary nebula,” so named because they looked similar to planets to early observers. m27 is known as the dumbbell nebula because of its visual appearance through a telescope.
tekkies:
sky-watcher esprit 150 f/7 refractor,
qhyccd16200-a camera,
optolong ha, o3, l, r, g and b filters,
paramount mx. acquisition with theskyx unguided.
focused with theskyx @focus3.
automation with ccdcommander.
all pre-processing and processing in pixinsight.
acquired from my skyshed in guelph.
no moon, average to excellent transparency and fair to above average seeing.
data acquired july 17-august 6, 2018.
18x10m l, 12x10m r, g and b, 31x20m ha and 17x20m o3 (total = 25hr).

Great l-pro, you should be able to withstand tests of hundreds way!
acts speak louder than words,optolong l-pro filter without any color deviation.
wei-guo shoot the galactic center by 2” optolong l-pro filter. great work!!!

M16 eagle nebula
l-pro not only improve contrast, but help revealing more details in darker blue areas.

M20 trifid nebula, is a typical emission nebula. the red ionized hydrogen is relatively easy to shoot, but neighbor- dark nebula with blue need longer exposure time.
if use cls or uhc, the blue ice giants will be cut. however, l-pro not only improve contrast, but help revealing more details in darker blue areas.

L-pro filter--love you stand the test
optolong l-pro is an abbreviation of l-professional, light pollution restraint and high transmittance of nebulae emission lines are two points of this type.
for the target object, the design of multi-bandpass with visible range 400-700nm, not rigidly natural flavor reinstated on subjective performance to express the feelings of colors, and reveal image details, which can be matched by no other experience. because other light pollution filter type cut most of the details.
in the light pollution environment, it is not only suitable for emission nebulae, reflection nebulae, but also for the objects with continuous spectrum so that make nebulae easier to see.
visually, l-pro guarantee large amount of nebula emission through, and block certain types of artificial lights, which improving contrast efficiency of the object, not brightness..
with ccd and dslr are better choice for deep sky photography and wide-field astrophotography.
l-pro spectral line of emission
high transmittance at oiii(496nm&500nm), hβ(486nm)、nii(654nm&658nm)、ha(656nm)and sii(672nm).
it would be effective in blocking city na(589nm/616nm), hg(435nm/578nm), and other artificial lights.
