Horsehead Nebula and Deep Space Objects in Orion

Several deep space objects on Orion constellation is amazing for me or for many people, why its amazing?
because you cant see several nebula on Orion without additional filter Telescope.
for example: “horsehead nebula”  (also known as Barnard 33 in bright nebula IC 434) its difficult to see without add special filter in telescope.
larger aperture of telescope is also need to see “horsehead nebula”.
there is a special filter that one could use to see objects such as the Horsehead nebula, It’s called a hydrogen-beta filter.
if you don’t want to spend lot money (because the price of hydrogen-beta filter is expensive) on a filter, that will only be useful on a handful of objects, the filter more cheap is Lumicon UHC filter, which is a narrow band filter.
This is a good, general purpose filter and may help you in your search.
It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse’s head when viewed from Earth.
minimum size that recommend from many people is an 8″ of aperture telescope.
Of course, the larger the telescope the better. Don’t be disappointed by negative sightings with bigger instruments.
Seeing conditions and experience have a lot to do with viewing the Horsehead nebula.

the famous nebula in Orion is a bright nebula called “Orion nebula” or M42.
you can visit my post about “Orion nebula” in this LINK.
Hanging from Orion’s belt is his sword, consisting of the multiple stars called Trapezium and the Orion Nebula (M42).
This is a spectacular object which can be clearly identified with the naked eye as something other than a star; using binoculars, its swirling clouds of nascent stars, luminous gas, and dust can be observed.

Besides these nebulae, surveying Orion with a small telescope will reveal a wealth of interesting deep sky objects, including M43, M78, as well as multiple stars including Iota Orionis and Sigma Orionis.
A larger telescope may reveal objects such as Barnard’s Loop, the Flame Nebula (NGC 2024), as well as fainter and tighter multiple stars and nebulae.
All of these nebulae are part of the larger Orion Molecular Cloud Complex which is located approximately 1,500 light-years away and is hundreds of light-years across.
It is one of the most intense regions of stellar formation visible in our galaxy.
