Nice! My AstroTrac tracking mount is essentially a fancy barndoor device but it does a good job.

Thanks.
If you saw the rig that I put together you might question my sanity
The oscillations are really nasty, I can`t even look at it without it going nuts. And counting "one Mississippi, two Mississippi" is starting to get to me. Might be time to bite the bullet and invest in real GEQ mount.

In this picture,I'm not sure the line is a Meteor or a Satellite.

105mm 90sec exposure ISO1250 F2.8
PENTAX K-5 ,SIGMA 105mm/2.8 EX Macro ,SkyTracker

Given the exposure length and the sudden beginning/end of the line in the middle, it looks to me like a satellite trail. An Iridium-type satellite brightens and fades in a characteristic way over 10 to 15 seconds, similar to the left hand part of the trail.

Moonlight Versus Light Pollution

Captured via piggyback mounted on my Nexstar 8se while trying to spot some meteors.

Moon was bright and high in the sky and the artificial light glow from the city around me was competing for sky dominance.

I want to shoot Lovejoy now that ISON is considered dead, but the whole of december has been 80-100% cloudiness during night and the reports says that it will continue.

Lovejoy is at perihelion Dec 23rd and is not a sungrazer as was ISON so it will survive its close encounter. Thursday morning will be my next best opportunity to snag it since we by some miracle will have about 18 hours of clear skies starting Wednesday afternoon. Some beautiful images showing up now on Spaceweather.com.

M42 Orion Nebula

First attempt at M42 The Great Orion Nebula. It was very windy that night so I had to limit my exposures to 2 minutes. Any longer and the wind gusts were destroying the exposures.

Celestron Nexstar 8se, homemade wedge, meade off axis guider, ZWO ASI120MM guide camera, and of course the trusty Pentax k5.

I'd be happy with that.

I cant get more than 10 second exposures out of my barn-door and EON 120ED 900mm f/l f7.5 refractor.
Here is one from last night, nowhere near as nice as the one from seti_v2.

Congratulations. I assume you're using the f6.3 reducer. It looks like you solved your earlier internal reflection problem.

A ZWO camera is on my shopping list. Still undecided between color or B&W. B&W is a bit better for autoguiding and offers the potential of higher resolution for planetary imaging, but color is so much easier for planetary imaging.

Yes, I'm using the f6.3 reducer.

I got the B&W ASI camera. Meade is running a deal for the tricolor LRGB interference filters for only $19.99. I jumped on that as well for doing tricolor planetary imaging. Meade Deep Sky Imager RGB Color Filter Set for use with DSI PRO

They are standard 1.25" filters and interference ones to boot!

This is starting to feel like work, too much post processing involved.
The K5 does do well for astro however.

Cheers.

i like the color balance on the reprocessed on ExFinn! M42 is such a bear to process, too much dynamic range in it.

M42 Reprocess

Spent a long time reprocessing to bring out as much detail as I could.
