  1. Yes, like I stated way earlier, conditions, aperture and exit pupil all contribute to whether a particular filter works or not. I find broadband filters can often be more effective on smaller apertures. I can effectively use narrowband filters on an f/6, 150mm Newtonian, yet this isn't always the case on an f/6.9, 130mm Newtonian. I've had similar results to you with an 80mm f'5 refractor. Conditions dictate filter usefulness in my experience.
  2. I'm not the one arguing with an opinion. As I stated: YMMV. I don't care if someone disagrees with my opinion. That's what forums are for. I think you have to look who's causing the enmity here. There is trolling on this forum. But it isn't by me. I don't reply to (or feed) trolls.
  3. I have an original Lumicon UHC, I'm not really sure what's happened with Lumicon now. I've heard they aren't what they were. Not long ago I directly compared a Lumicon UHC, an Orion UltraBlock, an Astronomik UHC-E, an Orion SkyGlow and a Baader UHC-S on The Orion Nebula. The telescope was a 102mm SkyMax (Maksutov) and I used a variety of magnifications and eyepieces and mainly kept the exit pupil above 3mm. Eyepieces included a 40mm Plossl and 23mm and 25mm eyepieces equipped with 0.5x reducers effectively doubling their focal lengths. The results were that the Orion SkyGl
  4. My sky is like yours (I live in a village on the edge of the greenbelt) and the 30mm Vixen gives me a dark enough background, as does a 25mm NPL and a 19mm TeleVue Panoptic.
  5. You're welcome. If your scope has a 650mm focal length it will be f/5. The 30mm Vixen is a superb Plossl.
  6. The Sky-Watcher 32mm Plossl is pretty good, it's the same as the Celestron and Orion among others and actually manufactured by Barsta. I wouldn't recommend it for scopes faster than f/6 though as you may get astigmatism (flock of seagulls effect lol). The GSO/Revelation performs better in faster scopes. https://www.365astronomy.com/32mm-GSO-Plossl-Eyepiece.html https://www.telescopehouse.com/eyepieces/revelation-eyepieces/revelation-32-0mm-plossl-eyepiece-1-25.html The 30mm Vixen NPL is superb as well and is one of my main low power EP's when using f/5 short tube refractors
  7. I'm fairly sure Lumicon developed the first UHC (Ultra High Contrast) 'narrowband' filters. Narrowband filters normally transmit between 484 and 506 nanometres. In my experience narrowband filters can be of limited use on many emission nebulae, where a broadband filter can reveal more detail. This is also related to aperture and exit pupil. I found that a Lumicon UHC was of limited use on a reflecting telescope under 15 centimetres when used to view emission nebulae like M42 (Orion Nebula), M8 (Lagoon Nebula) and M20 (Trifid Nebula), the latter technically being a combination of emission and r
  8. Anything was better than the dead ducks that were the SWAN's lol.
  9. The Sky-Watcher MA eyepieces are basically inexpensive reversed Kellners with plastic housings. The Barsta (BST) eyepieces are a totally different kettle of fish. I only have the 3.2mm & 25mm but they are very sharp, bright and contrasted on f/5 refractors and an f/6 Newtonian. The 25mm Barsta and 3.2mm has five lenses in three groups including ED glass. I have a feeling the configuration is similar to many TMB types. These EP's are marketed under a variety of names. Maybe it's the ED glass (Extra Low Dispersion) or the design, but these eyepieces hold their own against much mor
  10. I like KStars, it can be quirky, but free astronomy stuff can't be bad lol. I had my 102mm Mak/AZ5 out this evening as the sun was out and I tried to catch a setting Venus and Mercury. I had all my filters and everything ready. At about 18:20 GMT I glanced Venus first with the naked eye, then in the RACI. By the time my eye got to the actual eyepiece clouds obscured everything. I didn't see it again!
  11. What gets me is the 'TS Optics' 2.5x GSO Barlow is sold by Telescope House as a 'Revelation Astro' for half the price of the TS Optics, and then some. I wish I'd have known!
  12. I don't know if the two companies are connected. They're both German. AFAIK 'Omegon' is the house name for Astroshop.eu. Astroshop/Omegon often sell TS products. TS Optics themselves market a lot of Barsta (BST) and GSO products under their own name. Above is the modified case of a 'Celestron' AstroMaster Accessory Kit I bought a few years ago. Astroshop sell the same kit as the Omegon AstroMaster. The 'Omegon' Barlow you can see on the left in the case is actually Barsta and FLO now sell it for quite a bit less than I paid for the Omegon version as a BST Barlow. The larger Barlow
  13. I wonder if these Omegon AC 80/400 OTA's are Synta. Does anyone have any info on these? They can be bought off Amazon as well as directly from Astroshop. https://www.astroshop.eu/telescopes/omegon-telescope-ac-80-400-ota/p,47423 They look more or less identical to the ST80 variants distributed by Sky-Watcher and Orion.
  14. @N3ptune Hey Neb, I forgot to ask, do you use KStars on Mint? It’s in the Ubuntu repo. There’s even a stripped down Android version. I believe it can be compiled for Windows. It seems mainly used on Linux. The ‘droid version is glitchy but it’s OK for freeware. The repo version seems fine although it might not be the latest release. It’s developed by KDE and I’m pretty sure runs on anything Debian/Ubuntu based. It's good for planning sessions but can also control a GOTO apparently. https://edu.kde.org/kstars/ Blurb ~ KStars is free, open source,
