Hi, I just published a video of how I am cleaning my filters - I thought I might do this while my telescope is back at service due to some kind of astigmatism. How do you guys clean your filters? it seems that every dust particle finds it way to the filters just as you are done cleaning them, and to sit in a damp bathroom seems kind of a mess... Anyway, here is the video / Daniel

As I have replaced them with new-style versions, I have two old-style ZWO 36mm unmounted narrowband filters for sale: - H-alpha - S-II They are pre-2018, so with both sides silver instead of yellow&purple, and come in the original, but opened, packaging. Condition like new. Attached images have been made with them. Any decent price will do. Nicolàs -
Hello I am wondering if anyone has a suggestion that might help me My imaging set up is an RC reflector with an FLI proline 16803 camera and 50mm Astrodon filters (LRGB + 5nm narrow band) I have had a string of issues...everything from my mount had mechanical problems to my telescope had issues with the mirror cell to some family distractions...but at long last I seem to have everything working with the exception of the Astrodon Ha filter. Attached are representative 30minute subframes of the horse head and Pacman nebulae in Ha, SII, and OIII. I get similar results with di -
Hi all, my second attempt at imaging over multiple nights, captured 60 mins Ha and a couple of 5 mins on Oiii and Sii on Christmas evening, then added more Oii and Sii on the 30th Total of 60 mins Ha 25 mins Sii and 30 mins Oiii Hubble mapped - SII,Ha,OIII = R,G,B. The Oiii data was very noisy but I'm fairly happy overall, also the ZWO Oiii filter caused a massive ring around Alnitak when stretched ! Comments welcome, I know it needs more data and I will need to learn to be more patient but the year is running out Thanks for looking and have a good 2020.

I went to my family house in the countryside and was able to take some pictures during xmas eve. Total exposure: 6h H_Alpha: ~3h (730x15s) --> R, G Oxigen III: ~3h (710x15s) --> B, G I didn't have a view on Polaris and could not spend too much time drift aligning (it was xmas eve after all :D) hence the short exposures. Moreover I dont have the proper connection rings to put my flattener on my mono camera so all stars off center are a mess :_(.

THIS ITEM HAS NOW BEEN SOLD. This listing is for my personal narrowband filters (Kayron from Light Vortex Astronomy). They are the Astrodon Hydrogen-Alpha (HA), Oxygen-III (OIII) and Sulphur-II (SII) 3nm 1.25" narrowband set. These are considered the highest-end narrowband filters money can buy, able to produce images of exceptional quality and incredible sharpness, cutting through a vast amount of light pollution. The 3nm variants featured here are fantastic for pulling out fine nebulous structures clearly above background. For more information, please see Astrodon's website: https: -
The bubble nebula. Not much to add about the target itself as it is already popular enough. A combination of HOO shot with the ASI1600MMC + Astronomik narrowband filters through the 200mm newtonian tube removed from the dobson base and put on the EQ6-R. About 6h of exposure through the Oxygen filter and about 9h through the Hydrogen filter. Clicking on the pictures will redirect to the astrobin images where you can watch them in full resolution. Crop close-up And widefield Thanks for watching and clear skies to you too! Alex

Hi everyone, The North America and Pelican nebulae are situated in the Cygnus constellation and are thought to be 1800 light years away. My favourite part of the image is "The Wall", which is the "Mexico" part of the North America nebula and is a source of intense star formation. The data for this image was collected all on one night and therefore could do with more integration, but I like the result. I've used my go-to "natural blend" narrowband (as originally suggested by Jon Rista on Cloudy Nights): R = 76%*Ha + 24%*SII G = OIII B = 85%*OIII + 15%*Ha I personally pre

Finally completed my SHO version. There is some purple in the image I cannot figure out how to get rid of and I'm sick of playing with it. Hints and tips on how to get rid of it welcome, I'm using PixInsight. https://pbase.com/grahammeyer/image/169136922 Scroll to the bottom for size options and details. Thanks for looking!

Hello Astro Peeps, I hope everyone is all good! Isn't there some amazing images on this site and others. Amateur imaging has never been so good! I myself have finally managed to get some data for an image, of which I am very happy. It has been so hot here it has been impossible to get any good data. One day a couple of months ago, I hung the thermometer from the grape vine under the back verandah and it was 47.5°C. Sounds far fetched, although true. I live in Adelaide, South Australia and we are 11km from the CBD and usually 1.5 degrees hotter than there! Anyway, I thought I'd try my

Hi everyone! The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago. A number of firsts with this image: 1. My first mosaic - keeping it simple with two panes! 2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night 3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well! APP was used for pre-processing -
Here's my effort from 2 nights ago under an increasingly rare clear and moonless night 1hr each of HA:OIII;SII using a Skywatcher esprit ED80 and ATIK 460 camera.

Hello from Florida, ? I wasn't able to image the 4th and final day as AR2729 rounded the limb due to work, but I was able to latch on for three days while it had lovely visible umbra. This is spanning December 5th, 6th and 7th. Imaged in 6562.8A wavelength. B&W: Colored: Captured with: Celestron 150mm F8 Refractor (CR150HD) Daystar 150mm ERF Daystar Quark Chromosphere ASI174MM Camera with 2" GSO 0.5x Focal Reducer Very best,

EQ6-R Pro, ASI1600MM, ED120 + 0.85x reducer, Astronomik 6nm Ha filter. 2 hours integration (30x240s) 50 darks, flats and dark-flats. Windy night, near full moon Captured via SGP, Guiding PHD2, Processed in photoshop. This is why I wanted to get into narrowband imaging, Taken on Sunday night from south Edinburgh (Bortle class 6) with a nearly full moon in the sky (95%) and I can still make the most of the limited opportunities we get here. OIII filter is next on the list.

I am going through the motions of properly processing my first narrowband image. Perhaps there is no difference here to LRGB, but I am curious as to which method people favour for their work-flow and why: A: Combine the channels (using SHO palette in my sitution) and then apply DBE; or B: Apply DBE to each channel and then combine? Mainly interested in nebulae. Thanks in advance for any thoughts on this. -
Hi all! I'm about to embark on my first narrowband imaging session tonight. If you're happy to share, I'd be interested to know the one thing you wish you had been told before you started with narrowband, what challenge it caused you and how you overcame that challenge? For some context, I've been imaging LRGB to now so have some general experience. Tonight, I'll be using an ed80 pro refractor with 0.85 reducer, moonlite focuser and motor, OAG, asi185mc guidecam, efw, asi1600mm-c on an azeq6gt. Filters are baader ha 7nm, OIII 8.5nm and Si 8nm, all 1.25". I'll be usi

Having acquired an ASI 1600MM Pro earlier in the year, this is my first attempt at a wide field Ha/OIII bicolour, using a Borg 55FL scope. 15 x 240s Ha and 15 x 240s OIII, integrated and combined in APP and edited in Star Tools. I assigned Ha to the Red Channel and OIII to Blue and Green, but would be grateful for any tips on combining channels for bi-colour images. I also tried combining with the LRGB Tool in Star Tools, assigning Ha to Red and OIII to Green, allowing STar Tools to synthesise the missing data. The result was interesting, but did not produce the 'traditional' Red/Cya

Hey-ho So then, just as i thought the DSO season was well and truly over for me until late August/early September, as it turned out last Saturday night (May 5th) was mostly clear, so i set about trying to finish the NAN image i had captured in Ha a while back (see thread below): So all i needed was some OIII. It's obviously not the ideal time of year to capture this i know, as it's so low on the horizon, but beggar's can't be choosers so i tried my best to make the most of the small amount of astro dark time available and just make the best of it. In the end i managed 9 subs, t
