NGC 6164

NGC 6164 – is a bi-polar emission nebulae in the constellation Norma. It is about 4200 light years away and its about 4 light years across. It has some fairly enthusiastic stellar winds – around 8 million km per hour.

NGC 6164 - 2

This image is taken in narrowband – 3nm HA, OIII. Ha is mapped to Red, OIII is mapped to Green and Blue. This is 70 subframes, 1200 s each @ -20C, 2×2 Bin.

M16 – The Eagle Nebulae

Final M16 - 2

Final M16 - 2 -  Zoom

This is the Eagle Nebulae – M16. Ive taken a few liberties with the colours, its taken with narrowband (Ha, SII, OIII) filters anyway. The first photo is of the entire area – so you can attempt to imagine the eagle – and the second is more focused on the area called the “pillars or creation” https://en.wikipedia.org/wiki/Pillars_of_Creation from the famous Hubble shot. You can see how the pillars actually look “deeper, 3D(?)” that the rest of the surrounding material.

It is 13 subs of HA, SII, OIII – 1200 sec each @ -20 2×2 Bin

The Gear is found here.

Equipment

Got sick of typing this for every image so here is the gear I’m using to take these photos:

1. Planewave CDK 20″, with Silica primary mirror.
2. Astrodon Filters, LRGB, IR, and for narrowbands 3nm HA, SII, OIII
3. Ultrastar for guiding
4. FLI Proline 16803
5. Maxim DL for photos and guiding.
6. FocusMax 4 for focusing.
7. Planewave Ascension HR 200 Mount
8. Astrodon MMOAG
9. Planewave Rotator, Focuser – IRF 90
10. Hendrick heated USB Hub

Field of view is 0.61 x 0.61 degrees, 1.08 arcsec/pixel.

All of course hosted at iTelescope.net

NGC 3579

NGC 3579 (and friends) in narrowband – hubble pallette. Gear is found here, 900 Sec subs (8 each filter) 2×2 bin @ -20C.

NGC3579

Processed in PixInsight – still have my “L” plates on.

The Moon

So while the moon is near full and destroying all my photos I thought Id take a pic of it.

This one is with the usual Planewave, FLI, 1×1 bin, -20 C, but the subs are each 0.5 seconds with Ha, SII and OIII 3nm filters combined (only 1 per filter) to give RGB, weird I know but I was playing. Note that some of the subs are still so bright the max’ed out the sensor, check out the very bright white spots for this effect.
