I got a new telescope a few weeks ago, a Skywatcher 150P-DS, and I've just had it out yesterday, as the danish summer has been absolutely horrendous.. But it's only just now, that the astro-dark nights are returning again anyway. And what better easy target to test it out on, than the Andromeda Galaxy? :D But there were only like a total of 2-3 cloudless hours yesterday, so I only managed to get 26.5 minutes of 30 second subs, as I was also observing and getting used to the new scope.
The focus is a slight bit off, as I've still to make a bahtinov mask that fits this one, and I can see that I really do need to get my hands on a coma-corrector. I am currently looking at the Explore Scientific HR Coma Corrector. People have recommended the Baader Mark-III MPCC, but some have also complained about it introducing spherical aberration?

Other than those issues, I am very pleased with the quality of this scope and how easy it was to produce these images. Just the fact that the DSLR can actually reach prime-focus, without the use of a barlow-lens or something similar, is just a big plus compared to what I've had to deal with!  I'll give it some longer tests when the next dark, cloudless nights hits, which might be a while! :p
The field of view of the 150P-DS is a bit too small for something like M32, so I might make a 2-pane mosaic sometime.

Nice first catch!

I use the baader cc with my 150pds, and it works fine. I also found that it takes the focus a bit further out.

A Bahtinov mask is a good investment. If you make your own, try to make the edges as clean as possible; it will improve the diffraction spikes.

A motorised focuser is also a good investment. I found that focus can shift slightly when I tighten the focus lock.

Have fun with your new scope!

      This a rework of data I captured last november.
      Previously the intent was to reveal the faint dust lanes within this galaxy. Now I aimed for the very faint tidal stream that connects this galaxy to its neighbour M31.
      The stream is the result of gravitational interactions between M110 and M31.

      (click on the image for a larger version)
      To show the tidal structure and weak halo surrounding M110, here's an inverted and superstretched version.

      2.2 hours of integration time is really not enough to do this target justice, so I will add to it later this year.
      Image details:
      L: 14 x 3 minutes, gain 0, -30 C RGB 6 x 5 minutes (each), gain 0, -30 C total integration time: 2.2 hours Processed in PixInsight
      (Gear as per my signature.)

      You could call this my first proper attempt at andromeda, thought I've imaged it quite a few times now. But this is the first time I've managed to get most of it in one picture, which required me to do a two-pane mosaic.
      The left side of the mosaic is stitched 27 subs of 2 minutes ISO 3200, while the right side is 28 subs, + 1 sub of 8 minutes ISO 800 (just to test what difference exposure contra ISO does to details).

      I am very pleased with the result of it, but I also discovered some of the pains of doing mosaics, as getting an even background was very hard. Gradient X-terminator would do a decent job, but couldn't quite nail it, so I used it in conjunction with a few other techniques. The stitching was easy and painless, as I just used Microsoft ICE.

      Some feedback on the processing would be lovely, as I am not sure if this is my final version. I've starred myself blind processing it..
