This is the Centaurus-A
The subs are 5 min a piece in LRGB. 10 subs each 2×2 bin @ -20C.
Equipment is here.
Its about 10 million light years away, strange shape from the side on – see the details here
NGC 4038 The Antennae Galaxy.
Subs – 8 each of LRGB, -20C, 2×2 Bin, 1200 secs each.
Gear is found here
180 Second LRGB Subs, 10 each. -20C, 2×2 Bin

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 (and friends) in narrowband – hubble pallette. Gear is found here, 900 Sec subs (8 each filter) 2×2 bin @ -20C.
Processed in PixInsight – still have my “L” plates on.
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.
This was taken from Govetts Leap, Prince George Lookout, it was so windy the tripod kept wanting to blow over. It is a 20 second, ISO 6400 shot, taken with a Sony a7s 24mm F4 lens, using an iOptron SkyTracker. That’s the LMC down the bottom in the trees.

Every Astronomer needs at least one star trails photo. This one from the back yard. Taken on a Sony a7S, 24mm lens, F4, exposure 15 sec @ ISO 400. 2 1/2 hours of elapsed time, no moon. Processing with StarTrails.
