  1. Selling my LRGB filters 36mm unmounted , because I decided to use only my Narrowband and to invest in something else that I want. The filters are placed inside my Atik EFW2 at the moment but I can send photos if someone is really interested , so I don't loose my cc'd setup position. Are in excellent condition ,sold in their original boxes. The filters are well known so not much words need to say. Some info you can find here at Astrodons site: https://astrodon.com/products/astrodon-lrgb-gen2-e-series-tru-balance-filters/ The retail price is about £800 if I am not mistaken I will sell it for £500..............£375 Other offers can be accepted within reasonable price Payment via PAYPAL is accepted, buyer pays the fees. I post them from Athens Greece in A class shipment secured. I will pay the postage expenses. Thank you, Nikolas.
  2. THIS ITEM HAS NOW BEEN SOLD. This listing is for my personal narrowband filters (Kayron from Light Vortex Astronomy).

  4. Hello, I have a question about filterwheels; SBIG filter wheels specifically. As far as I know they are the only ones that really use the 8 position filter wheels. So I have it loaded with L, R, G, B, Ha, OIII, and SII. So that is seven filters, what goes in the 8th slot??? Thank you for your insight, Christopher
  5. Hello my first question (takes deep breath) I’m looking at buying a moon filter I have a nexstar 6se, now it’s possible I’ve had an information overload but I’m sure I read or watched a video that said SCT type scopes dim the light of the image because of the design with that said the standard density of a moon filter I’m looking at (Baader Neutral Density Moon filters) is 0.9. Because of image being dim (if that’s correct)would I be better off getting a filter with 0.6 density to avoid the image being too dim. i know the filter is there to help your eyesight etc ive had the scope for a couple of days and haven’t actually used it during the night yet so I have no idea how bright the moon would be. Any advice would be much appreciated even to tell me I’m barking up the wrong tree Andy
  6. Probably a stupid question... Heyyy soo i am a begginer and about to buy my first telescope.A Skywatcher 200 p. I ve just though of something , Since i know filters can be stacked i ve been wondering if i could take visual RGB filters and stack them.Specifically blue green and red in order to create a visual full colour image ,like photography. I know its probably a stupid question because people all over the world would have done this by now .But i m just curious. -Kronos
  7. I can't find any clip in Light pollution filters for Nikon cameras, specifically my trusty D90. Does anyone know where I can get my hands on one? it's been suggested that I just get a cannon already and I might in a few years but not now! I have found this Optolong UHC Ultra High Contrast Filter - Nikon D5000, D5100 Clip filter, but I don't know if it will work with a Nikon d90? any advice would be appreciated! cheers
  8. Looking at getting a light pollution filter, for my camera as I'm in a bortle 5 area and not currently using any filters. I've been looking around and the clip in filters are way out of budget, for now, so I've been looking at the Hoya filters and the red intensity filters. Then I saw these from Globe (Link Below), and thought maybe it's too good to be true? All those filters for the price of one Hoya? Has anyone used these before what do you think? https://mygobe.com/uk/52mm-collection-filter-kit-1peak.html?fbclid=IwAR3Uqu_TDPx-uxun3SGnDl8CqFQ-8kGgooW62Ux3gSNJ9PitQJj1RQn3_NY
  9. Hi everyone ? I'm looking to take my first steps in buying more equipment than what came with my Skywatcher 200P, which was 25mm and 10mm lenses. I enjoy looking at planets, nebulae and managed to get my first look at Andromeda the other night which was amazing. Are there any filters or lenses (or anything else) less than £100 that I should consider buying to improve my viewing? Looking at the range of things available is a bit overwhelming. Thanks!
  10. Just wanted a bit of advice regarding mono imaging. I have a few filters that came with my second hand scope. They are all revelation filters I know these are not top quality but has anyone used these for imaging? I was looking at a light pollution filter found this on eBay https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F370861000046 im sure it’s not perfect but has anyone tried them or similar? at some point in the future I do plan to buy good filters and make a filter wheel but before spending more I want to make the most of what I have unless it’s entirely futile to try
  11. Hi, when I get my 130p I would like to do some solar viewing after seeing many posts on the forum looks quite interesting. I would like to know what’s the best type of filter there is to use. Also do I need any filters for the eyepiece it self? And do I need to buy anything to keep my scope and myself safe? For example a cover to put on over the scope to keep it from heating ? I was looking at this https://www.firstlightoptics.com/solar-filters/astrozap-baader-solar-filter.html sky and telescope done a article and mentioned the Baader to be the best one is this the one they are talking about? ( apologies if this has already been mentioned and if it has please link the thread) Sorry if these seem obvious answers but want to make sure and be as safe as possible
  12. I'm selling my 1.25" baader H-alpha 7nm filter. I purchased it on amazon several months ago, but have never actually used it, as my CCD didn't work. (Its just been put in a filter wheel but never used!) As such it is in perfect condition. Price £75 including delivery to a UK address. Payment via Paypal (buyer pays fees), Paypal friends, or bank transfer Any questions, please ask.
  13. Hi I'm selling my Baader 1.25" CCD RGB filters. They are used, but in excellent condition with no scratches or anything of the sort. Price £115 including delivery to a UK address. Payment via Paypal (buyer pays fees), Paypal friends, or bank transfer Any questions, please ask.
  14. Reading the forums, it seems certain filter types are best suited to certain DSOs, in particular different nebulae. If OIII filters are good for most nebulae, which nebulae benefit more from other types? If UHC filters help with contrast for galaxies & fainter DSOs, are there certain suffixed types better than others. Hydrogen Alpha, Beta & various other filters, get mentioned. What are those for?
  15. Please could you tell me were to get the pass bands for all UHC and oxy 3 filters, or please give options on the best. thank you.
  16. If you had a $100, or maybe $200 burning a hole in your astronomy funds pocket, what filter would you purchase FIRST, if you had none? Consider whether it could be used both for visual and AP. Also consider that all owned EP's (so far) are 1.25", but they are used in a 2" diagonal, that will also accept filters. What's the best bang for the buck? (I assume 1.25"), and if there's no significant difference between 1.25 and 2" filters, will $200 buy more than one 1.25", if so, what are the TWO filters you'd buy first? While typing all this, I considered that one of my T-adapters for my DSLR has a 1.25" end, the other is whatever size screws directly to the rear cell (for prime focus).
  17. Hi All, About to buy my first real scope and mount. I'm wondering if I can put upon you good folks to ask for your recommendations for the items in the title that will match up with and compliment the equipment I'm about to buy. Top of my list at this moment is the SW EQ6 Pro with either the Explorer 250PDS or 200PDS (depending on the all the other items that need to get to at least make it usable fairly usable to start with and how that affect the overall budget). If I have to (for cost at this time), I will drop to a SW HEQ5 Pro with the 200PDS. Fortunately, my girlfriend/partner loves the night sky but I know she will want to see 'results' in the EP straight away and will want to mainly look at our Solar system and the Moon (not that I don't) but she hates the cold and has limited patience for waiting to see anything deeper than those for now. Myself, apart from the above of course, would like to go deeper but also include astrophotography once I have got myself up to a decent level of familiarity with the kit. I have a humble Pentax K20D DSLR and my very old Pentax Spotmatic F (Wet film) camera (It's been with me for a long time and still gets used once in a while). I would very much appreciate your collective wisdom regarding the title items and fitting my DSLR (primarily) to either of the two OTA's above. What is the minimum I need to get, make/models that will get me going and that will complement each other and the system without having to take out a second mortgage just yet ;-) and get me off to a fairly good start. I'm sure you have all had these questions before and I apologise if your first thought is "not again" :-) ... It's just that I have been lurking in the background of the site for a few weeks now reading up as much as I can and trying to pull a list together but my brain seems to have turned to fog now and after reading something earlier to day of EP's and Barlow's and that the optics in them (for want of a better word) should be in 'harmony with each other and the system, I've completely lost where I thought I was going and then also the subjects and threads that I had been using to 'guide' me elsewhere on SGL. Many thanks in anticipation. Kind regards, Chris.
  18. I have an Orion UBlock, a Lumicron Olll, and a Baader Neodymium filter, all 1.25.” The Baader screws on nicely to all my Televue Plossyl and Delite EPs. However, while, both the Orion and the Lumicron fit well to my 32 and 15mm Plossyl, neither screws on tightly to my 25mm Plossyl or my 18.2 or 7mm Delite). All fit nicely to my 2X TeleVu Barlow. From several discussions on Cloudy Nights, it is apparent that that the issue of filter-fit mismatch is common. My main telescope is a Sky Watcher Pro ED100 AP refractor which accommodates my 1.25” EPS via a 1.25 / 2” adapter. My goal, then, is to make all my EP’s compatible with these filter types as well as to make the changing of filters more efficient. I could sell off my Olll and UBlock filters and buy the comparable Baader filters and assuming they fit all my EP, live with the inefficiency of changing filters in the dark. Or, I could acquire a 2” barrel extension to my 1.25/2” adapter and purchase 2” filters that would screw into the bottom of the extension barrel. I could then easily switch back and forth between my 1.25” EPs. In fact, extension barrels are cheap, so that I could even buy three of them, one each 2” filter. Does this solution make sense? Are there more reasonable solutions?
  19. Before I continue, I do know ND is neutral density. But my question.... It seems to be common knowledge that a filter of level ND 5 is needed when viewing the sun. My ND filters for my camera are ND 2,ND 4, ND 6, and so on. So can I use one of these to view/photograph the sun? If not, what is the difference between my ND camera filters and the other ND filter/film sheets everyone bought for the eclipse? I'm sorry but I am new to any photography with telescopes. It's almost embarrassing to say it's been in storage. So, Thank you to anyone and everyone that can help!
  20. Hi I will buying a Celestron 11" HD cassegrain and to save I need to buy most of the needed equipments since they are 2x -2.5x price in Asia and i would not want to end up with things I dont need. For eyepieces will a combination of Ethos 13, 17, 21, Nagler 31, Panoptic 41 or William swan 40 and a TPO 50mm. Any suggestions please? Im not really well versed yet with filters for planets and deep sky and other than sky viewing I will be using a Nikon D5500 for astrophotography and maybe buy a simple webcam. Any suggestions? Im also considering getting a JMI dual speed motored focuser....Any suggestions? I hope with your suggestions I can gather most of what I need since I will be bringing them home to Manila Philippines where there no astronomy stores. Thanks in advance.
  21. I'm thinking about buying a filter to improve the contrast on DSO's in my new 12". The question is, is there really a big difference between the UHC filters (baader, SW, etc) and the OIII filters? Will the OIII limit me to a certain amount of objects such as M27 and the veil? Thanks!
  22. Are the Baader LRGB filters parfocal with their narrowband filters, the Ha, O3 and S2 ones? I have Astronomik LRGB and Baader narrowband in my filterwheel. The narrowband filters need refocusing after LRGB which means I can't include then in an imaging sequence. I haven't managed to get autofocusing working in Maxim dl yet. I bought the LRGB first for a previous camera and then couldn't afford the 3nm Astronomik narrowband when I upgraded.
  23. I currently have an ultra high contrast filter - Zhumell High Performance UHC - and have had some luck seeing additional features in larger objects while using it. I was thinking about purchasing an Oxygen-III filter also, but wonder just how different is the O-III compared to the UHC? Is it worth the money to have both in my filter collection? My scope is only a 130mm, and I would love to see additional details while finding and viewing DSOs such as Dumbbell and Ring nebulae, see more details in Eagle, Trifid, etc. It would be awesome to find something that would also enhance galaxies too (M31, M33 etc.). Does anyone know if an O-III filter will perform better than my current UHC filter?
  24. Good morning, I'm close to purchase the ASI1600 with the filter wheel and OAG. I have a couple of questions about the filters: Is it worth to go for the Baader LRGB? Or can I go for the ZWO ones (maybe are Optlong?). Some bad reports on the L filter on the later. For narrow band I was thinking on the Astrodons: 5nm Halpha, 3nm OIII and SII. I don't want to go for the 3nm Halpha and the same NII... not high polluted area, less filters. Am I right? Always looking for a balance price-caracteristics. About the size, 31mm unmounted. Thanks so much for your help, Aleix
