NGC6888 - Crescent in HA mono

Recommended Posts

Captured the data for this image on Saturday evening with an ~85% moon floating around, but pleased with the level of data I managed to get here. 

Taken using ST2000XM, Astrodon 5nm HA filter, through FLT110 at f5.6. This was first run after summer with a new adaptor between the drawtube of the FLT and the FLAT4 reducer - works brilliantly as it eliminates play found in the 2" nose/adaptor as before, and also reduces the vignetting as well. Exposures were 11 x 1200sec with APT; off-axis guiding with an ASI120MM and PHD2; reduction/processing in PI with final levels tweak in PS. 

So much background stuff here, I didn't bother with any DBE as couldn't really place the markers! Think the flats have worked nicely here though (tends to be less of an issue with backgrounds through HA anyhow). 

Thanks for looking!

Nice image, you don't see many people using the KAI2020 sensor cameras these days what with the KAF8300 and the ASI1600 being so dominant. Do you find that it still holds up ok / works with windows 10?

Thanks both :)

Yes, the 2020 is getting on a bit now (this camera is 12yo now!), but it performs well still. No issues with the drivers under win 7 (and I presume 10) - SBIG (well, Diffraction Ltd now) still support it and are still using the drivers. 

I would like to get another newer camera at some point - either a 8300 (though wary of RBI) or a ICX694 based camera (QE and noise great, but not much improvement in FOV...). Still not decided!

Well done, a nice mono image. Lots of fans of the 8300 chip here on SGL, but I'm a 694'er myself! Both great chips, you can't go wrong :)

Thanks John, 

The 694 is edging it or me at the moment for weight, sensitivity and cheaper filters, but the pixel size of the 8300 is better suited - it'll eventually be mostly used on a 14" newt when I get the tubes/dovetail milled by a mate. Here I won't get a multi-degree field like on a short 'frac and I'll often be chasing galaxies and smaller faint stuff (though the FLT is still an option). And I can use camera lenses still especially if mobile, where it will outperform my 350d.

But the FoV is still an attraction...!! Aargh!

Great looking Crescent :)

Regarding a camera...... Welcome to the hot debate of KAF8300 v's Sony chips!! I am a great fan of the KAF8300, it gives a bit of real estate for a reasonable price and if you get the right ones you can still use 1.25" filters.

But there is a place for the Sony chips for sure!! I have an ICX814 in my case as we speak as a new camera for the TMB 152/1200. Its a difficult decision to make!!

Thanks Sara - yeah, tricky one! Don't think I would find either bad at all, just which is best!!

      1. Alcyone (Eta Tauri, η Tau, 25 Tau) in the Pleiades open cluster, spectral type B7IIIe+A0V+A0V+F2V.
      This star is a multiple system, but my goal of observation was the H-alpha profile of the main component:

      Horizontal axis scaled to radial velocity:

       
      2. Pleione (28 Tau, BU Tau) also in M45, spectral type B8Vne, variable star, the brightness changes in range: 4.83 - 5.38 V. 
      This is the faintest star, which I observed with using APO 107/700 & Low Spec spectrograph 1800 l/mm. 
      It was difficult, but obervation was positive (high gain, exposure time 4 min):

       
      3. Tianguan (Zeta Tauri, ζ Tau), spectral type B1IVe+G8III: (mark ":" according to the VSX database means uncertainty).
      This is an eclipsing binary with variability type E/GS+GCAS, period is 133 d. The brightness changes in range: 2.80 - 3.17 V.

       
      4. Cih, Tsih (γ Cas), spectral type B0.5IVpe, variable star with a magnitude range of 1.6 to 3 V:

       
      5. Alnitak (Zeta Orionis, ζ Ori), spectral type O9.5Ibe+B0III. Variable star with a magnitude range of 1.74 to 1.77 V.
      Spectral lines have characteristic P Cygni profile, below H-alpha:

      I've just bought a Daystar Solar Scout 60mm DS for H-alpha imaging of the Sun. I am now looking for a suitable camera to use with it. I know I could use my DSLR, but for H-alpha that is not going to give best results, so am looking for a dedicated monochrome imaging camera. I have identified the ZWO ASI178MM as a possibility that fits my budget and has a large enough (I think) sensor to image the entire Solar disc if I use a 0.5 focal reducer which will give me a total focal length of 465 mm.
      Does anyone have any experience of this camera in this application, or know if it will be suitable? I know it does not have an IR blocking filter, which I understand is an advantage for H-alpha. The spec is available here:

      Thanks

      Hi all.
      I am looking for a zoom eyepiece to 60mm lunt. My first choices are Lunt zoom and Pantax smc xf zoom. Which will work better? Can you have any other offer? You could say something more about these eyepieces while observing h-alpha?

      I bought this filter about one year ago with the aim to protect both my Tak-100 DF and a Quark eyepiece which eventually I never bought. Therefore, I am selling it, hoping that it will go to a good home and be used as it deserves. 
      It is a top quality Baader ERF for solar viewing with Quarks. It is in excellent condition and comes complete with housing measuring 146mm. The previous owner used to fit it on an Altair 115mm F7 refractor. With some minor modification (essentially adding some padding to the internal side of the housing) it can be fitted on many other telescopes.
      It cost £550 but selling for £320 including postage. I will accept PayPal (pay as a friend) or direct bank transfer.
      Also advertised on ABS.
      Thank you for looking,
      Piero

      Dear all,
      as suggested by Hughsie, here's my pastel sketch my contribution to the solar imaging challenge. 

      Telescope: Lunt LS50THaB600PT
      Eyepiece: Celestron X-Cel 10mm
      Date & Time: May 29th, 2019 / 1630-1700 CEST
      Location: home terrace, Dusseldorf region, Germany
      Technique: reddish Koh-i-Noor Toison d'Or pastels and pastel pens on greyish Canson Mi-Teintes pastel paper
      Like all of my astronomical sketches , I did this one directly at the eyepiece. The picture of the sketch is taken with my smartphone and just cropped.
      Clear (and sunny) skies!
      Achim
