What target we're you imaging with the 135mm?  Nice wide field of view with that lens

 

I was more less just testing guiding, though got a few of M31

This my latest version of the Soul Nebula in Cassiopiea. This is an Ha oiii with rgb stars added composite image. 

Skywatcher 130pds 

Cg4/eq 3-2 mount with eqstar pro beltmod. Skywatcher coma corrector. Canon 450d modified camera. Svbony 7nm Ha filter, astronomik 12nm oiii filter. 50/183 guidescope with t7c cam. Bortle 5 zone

Belt mod, must be a different CG-4 drive, I have the motors that connect directly to the worm gear shaft, no spur gears.

Yes big difference using MS guiding.

How consistent is your guiding over the period of a night, that's very impressive. I to have a cg4 mount. On a good night I get between .58 and .8 RMS. Did you find that multistar made much of a difference  I must get that up and running.

On this night first time with MS guiding it was consistent at around .50     I was using my ST80 as guide scope and piggybacked my DSLR with 135mm lens.

Got  31x180s at ISO800 last week from a B 4 sky. stacked it with some data from my B 8 home sky, 26x360s ISO200. 

My CG-4 with MS guiding.

Got a start on this target, 34x180s  ISO800 K50, CGEM DX. gonna try and get more hours next new Moon.

Thanks Brown dwarf and Neutron star,  I have been messing around with the hobby for a few years, mostly from my home Bortle 7-8 sky. Now that I have imaged from a 4 sky I don't want to bother from home anymore. I don't have any real processing skills , this was done in DSS then LR. I only used an old master Bias for calibration. Think I will make some flats today and maybe try some dark flats also. I see no real improvement using darks with the Pentax K50.

My best so far, 30x180s, ED80, K50, CGEM DX

85x180s ED80 K50 ISO 800 CGEM DX 

25x180s, Pentax K50 stock, CGEM DX, SW ED80. 

50x73s  at F2.8, Pentax K50 ,ISO800, CG-4 guided.

Thanks all, this was at my friends in NC . My main target for the night was M31, I checked focus then got 3 hours on it and was vary excited to see what I got. What I got was 62x180s with the mask still on the scope  lol... 

24x180s ED80 stock K50 ISO 800 CGEM DX from Bortle 4 sky 

First light with new Rokinon 135mm F2.  28x30s ISO 800 stock K50

My PHD2 graph with CG-4 

Thanks guys, this was with my K50. I believe it has that good Sony sensor.

37 x180s ISO 800 

I added a guide port to my CG-4  175 lights  30% were 240s with Orion sky glow filter, the rest were 120s no filter. total 7 hours
