A Horse Head nebula - 5x1800 sec  Ha. Acquisition from november 2014, with MN190 on EQ6 belt drive/EQMOD, Atik314 L+ mono camera. The FWHM had a medium value of 3.6, wich is very much for my set-up (I had often 1.9). But the result is quite good. Hope you like it as well.

A picture I think I didn't post here (really?...) but I like it very much!

Here it is my Dumbbel nebula from this year. A narrowband composition Ha-OIII-OIII, 8x1200 sec Ha and 9x1200 sec OIII.
Aquisition with MN190/EQ6-belt drive/EQMOD, Atik314L+mono, guided by OAG/QHY5IIL mono. Processed in MaximDL (calibration and stacking), PI (registering, color calibration), StarTools (fine tunning).

This is my 2014 try to Bubble nebula, for the moment only Ha.
The OIII and SII shots will follow.

This is the intermediate result using 7 hours 55 minutes of exposure in H alpha and 4 hours in OIII, combining these as colors - R=Ha, G=OIII, B=OIII, color balance 1/4/4. I used MaximDL  for acquisition, calibrating, combining and stretching exposures, Photoshop for levels and curves and StarTools for fine tuning.
I will add SII exposures I already have to see what it will look like in the end. 
The stars halos are from OIII filter, this is a malfunction of the filter.

I insisted a bit on Heat Nebula, trying to obtain as much signal and resolution as I can, so last night I added 24 exposures, 900 sec each, again in H-alpha. Than I selected 21x900 sec and 8x1200 sec from previous session and the result seems to me to be much better. In the next nights, i will add some extra exposures in Ha and exposures in SII and OIII to obtain another picture in Hubble palette (narrow-band).

Another shot, this time 7 hours integration of 1200 sec exposures in H-alpha. The sky region is called Heart Nebula. This is just a detail of it because my set-up have a small field of view.
