Robert Watson Posted February 14, 2010 Share Posted February 14, 2010 Hi out there, I've been trying for a few nights now to see the horse head neb i know where it is but i just can't see it. M43 no prob's.I've got a 10" skywatcher skyliner 250px auto dob 6-9-12-25mm +barlow len's i've mixed and matched but on luck.Is my scope just not big enough. I live in N Ire we've had some great sky's this week , can anyone help please. Mant thank's robert:icon_scratch: Link to comment Share on other sites More sharing options...
John Posted February 14, 2010 Share Posted February 14, 2010 It's an incredibly difficult object to see I believe (I've not managed to se it either as yet). It needs very dark, transparent skies, good aperture (I think 10" might be on the small side) and a Hydrogen Beta filter I believe. I know folks with 16" scopes that have also not been able to see this object.So you are not alone ! Link to comment Share on other sites More sharing options...
Robert Watson Posted February 15, 2010 Author Share Posted February 15, 2010 Thanks John tried again tonight buit with no joy. Got some other good images though. Gonna have another go with a TD-35 electronic eye-piece. But it's nice to know that I'm not the only one who is having trouble! Thanks,Robert Link to comment Share on other sites More sharing options...
John Posted February 15, 2010 Share Posted February 15, 2010 Is the TD-35 image intensified Robert ? - if it is that might help move the odds of seeing the horsehead visually a bit in the observers favour ! Link to comment Share on other sites More sharing options...
Robert Watson Posted February 15, 2010 Author Share Posted February 15, 2010 Hi John ,Yes it is intensified ,my only prob its linked upto my etx 70 beside the computer in a bedroom so untill i can pinch my son's laptop and get it outside to the dob i'll just have to look for other neb's.mybe you can help me with this one , I was looking at Pleiades tonight in the middle their are 4 star's 3 in a triangle and one large and much brighter ,it had like a gas cloud around it but it looked more like a Galaxy, Have you ever seen this.Thanks robert Link to comment Share on other sites More sharing options...
Doc Posted February 15, 2010 Share Posted February 15, 2010 What scope was you looking at M45 with.In a large dob you might see some nebulosity surrounding the stars. There is no galaxy within M45 I'm afraid.You can also mistake dewed or steamed up optics for nebulosity. Link to comment Share on other sites More sharing options...
John Posted February 15, 2010 Share Posted February 15, 2010 I've seen traces of nebulosity surrounding some of the Pleiades stars when using a UHC filter and an 8" scope. Link to comment Share on other sites More sharing options...
Robert Watson Posted February 15, 2010 Author Share Posted February 15, 2010 Hi mick, I was using a 10"Skywatcher it has a fan at the mirror so it won't mist up plus i was out with the scope for around an hour very clear sky's tonight temp droping a little, but a very good viewing nightThank,s robert Link to comment Share on other sites More sharing options...

TopHouse Posted February 15, 2010 Share Posted February 15, 2010 http://en.wikipedia.org/wiki/Pleiades_(star_cluster) more on the pleides nebulosity here, pleides is one of my faves. Link to comment Share on other sites More sharing options...
David Pavlich Posted February 16, 2010 Share Posted February 16, 2010 It's all but impossible unless you've got big aperture, very dark skies and the proper filter. And even then, all you'd see is a kind of notch in the nebulosity behing it. However, I saw it with a simple orange tubed Celestron C8...equipped with a Mallincam. And that was during a first quarter Moon and a plaza parking lot about 1000 yards away.David Link to comment Share on other sites More sharing options...

I have mistaken nebulosity as this a few times they look very similar. Link to comment Share on other sites More sharing options...
david's dob Posted February 16, 2010 Share Posted February 16, 2010 yeah iv'e tried to look for the horse head nebula, and that was without a filter, i definately think that you would need a really dark sky, a UHC filter, and a bigger adparture size.

Robert Watson Posted February 17, 2010 Author Share Posted February 17, 2010 hI all, That was another great night's viewing ,the star's are jumping out of the sky and the quarter moon was somthing else, we've got a bit of a frost coming down in N IrelandMick you might have been right about the eyepiece, i give it a clean before using it i still could see nebulosity around the brighter star's in Pleiades but not the same as lastnight.Jumping with joy seen my first cluster M35 Link to comment Share on other sites More sharing options...
