Which nebulas?

I use dimming either through a larger f ratio (reduced exit pupil at a mag seeing will support) or better yet my f7.5 frac with a binoviewer. Low power, small aperture and or a small exit pupil. Works for me.

I modify the amount o polarisation of the filter. Allows details to pop out, rather than hidden under glare.

A binoviewer is on my list, not cheap going on these forums...

I bought the Binotron 27s for a few reasons including a discussion with Russ. I told him my set up and wanted the binos to work with any of my scopes. He immediately knew what to do- he made an extension for the system to focus in my newts, no charge. This system works in my fracs and newts extremely well.

If I was over there I would look at the new Baaders, research them - but they look good to me. Good EP holders are a must.

I have the Astro Essentials Variable Polarising Moon Filter and it does a pretty good job on the moon. I like the fact i can change the amount of light passing.

I have those too, in fact compared with other filters relatively inexpensive. Not had any others to compare with.

@jetstreamI have not heard back from Astronomik but i had a very frustrating night last night on nebulas, so i want to buy a filter soon.

 

Would you go for the:

https://www.firstlightoptics.com/televue-filters/tele-vue-bandmate-oiii-filter.html

or

https://www.firstlightoptics.com/uhc-oiii-visual-filters/astronomik-oiii-filter.html

(unless there is another OIII from these companies i missed)

The price difference is marginal so happy for either you think it is better; you seemed very happy with your earlier post on TV but @Johnwas happy with his Astronomik.

@John has an older wider Astronomik, vg btw, I have one too.

Either OIII will be excellent I think, for me now the nod would go to the new TV OIII. I just can't believe it out contrasts my Lumicon-I thought it wouldn't be possible.

Please note that filters are not magic... you need dark transparent skies for these objects. I sold my house in town and moved up in the bush for dark skies...

I fully understand but if it can help with a few targets then i am ok with that. Last night i managed to see the NGC1514 but the nebula looked more like a diffuse haze so if it can pull some more detail that will be great. My skies are bortle 4 so not too bad (I can see part of milky way ok). I also managed to see part of the cone nebula.

I would go for the Tele Vue. The Astronomik is very good but for that small price difference I would go the Tele Vue. Apart from Gerry, I have read great reports on the Mk II Tele Vue Bandmate filters from a number of other sources as well.

The Mk I Bandmates were very mediocre though - I'm not surprised that they moved to a different manufacturer.

Ever tried to see a report on these:

https://www.astronomik.com/en/infrarot-passfilter-infrared-pass-filters/proplanet-807-filter.html

meant to help out with planets when poor seeing, however that could start another thread. 😃

How dark is it where you live, I have just Bortle 4 skies.

Yes the 807 is excellent!

thats the good news!

the bad news is that I cant see this range!!:bino2:

Im looking at the IR filters for lunar imaging btw.

Are you sure?

i saw some tiny patch of nebulosity in that area. unless it is called something else? I think it was part of the Christmas Tree nebula/area? could it have been something else?

Very good!

The Cone nebula is one of the hardest objects there is to see, much harder than the HH by many times.

Can you define Bortle 4 in your own words from your own observations?

The Bortle scale is a little losely defined, so I can see why you don't find it precise. A large range of SQM is covered each scale in the Bortle system.

Hence the interest in NV, I'd like to see Nebulae better, only possible using filters. 

Also I find SQM directional, towards London I don't really look as the sky as effected by light pollution. 


Below is close, but also quite a wide description.

  • the zodiacal light is still visible, but does not extend halfway to the zenith at dusk or dawn
  • light pollution domes visible in several directions
  • clouds are illuminated in the directions of the light sources, dark overhead
  • surroundings are clearly visible, even at a distance
  • the Milky Way well above the horizon is still impressive, but lacks detail
  • M33 is a difficult averted vision object, only visible when high in the sky
  • limiting magnitude with 12.5" reflector is 15.5

M33 needs a scope where I live.....

last night without the moon the sky was bright from the stars and can make out where the milky way is. i can usually see some of the open clusters as a smudge of bright patch without a telescope. the nebulas and galaxies  i have seen so far are bright withe sky being quite dark around them. i leave in the middle of nowhere with the closest town being over 10 miles away and smaller villages 5miles or so..

 

(sorry i though the question was towards me, but it will be good to see @Deadlakedefinition for comparison)

I get surprised thats classified as Bortle 4. family live near Brecon Beacons and thats Bortle 3, say > 21.5 SQM.

no definition by no means; just a smudge the size of a pea.

Nebula associated around S (15) Mon within the Christmas Tree cluster is detectable with moderate sized aperture within dark transparent sky. The larger portion of nebula associated around HD 47887 is a more difficult observation and profiles the Cone. Some more details here. https://observing.skyhound.com/archives/jan/NGC_2264.html
