Deep sky imaging  - 
 
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.

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.

Thanks +Cristian Danescu.  I'm using a DSLR but hope to transition to mono CCD one day.

The final bubble from 2013, a total exposure of 8.5 hours in Ha, SII and OIII, Hubble palette. I hope it will be better next year.

I made some OIII exposures to my previous pictures (H-alpha) and I combined them like this - R=Ha, G=Ha, B=OIII.
The result is nice and the picture gain volume now.
Enjoy!

Is Bubble Nebula, between Cassiopeia and Cepheus constellations. Take a sky map and you'll find out where is it, more precise.

Hi,
This is my first-light with the new Maksutov-Newtonian telescope, MN190. Is again Horse Head nebula, to see the differences between the set-ups.
This is a stack of 11 shoots x 600 sec, H-alpha filter 7nm, MN190 on EQ6 mount with EQMOD remote controlled, calibrate and stack in MaximDL, developed, deconvolved, sharpening, life, noise reduction and other with StarTools (amazing software). ATIK 314L+ camera, ORION SSAG guiding camera.
The color version will follow next days (I hope).

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).

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.

After a long time, I show you some shots made few night ago, on Bubble nebula (again) but with my new set-up, a Maksutov-Newtonian MN190. Everything from inside my new roll-of-roof observatory.
The 2 pictures are different processing on same exposures - 14 exp. x 900sec, dark, bias, no flats, Ha filter 7 nm.
One of the pictures show the filament structure of the hydrogen clouds and the second one, the density of same clouds.
Acquisition, calibration and stack with MaximDL, processing with StarTools (amazing software !!).

Unbelievable!! If ya look at the bubble, it looks like a head coming out of the dust, you can see the eyes & nose, wow!! then it looks like a person standing next to the head or it could be another head with a little head on top!! I think I better quit this aroma therapy!!  :-))

On 02.01.2013 I posted an image here took in Ha. This is the color version, I added SII and OIII signals. The set-up was the same, Equinox 80 and Atik314 L+. The color processing was mad by a friend of mine, my version was to reddish.
