Building the observatory...

     After 2 years of break I managed at the beginning of December 2014 to finish my observatory.
     At the first moment I wanted that someone else should build it but after seeing the estimated prices I know it that I will have to do it by myself. Estimated price for building and pier was set at 7.200 euros that about 8.100 dollars, for pier only they wanted 800 euros (about 900 dollars).
     Honestly, looking at the estimated prices, I wasn't sure what do do, should I cry or should I laugh?
So long story in a shorter form, the local garden stuff store has also some smaller build it by yourself - garden houses and the had on stock one with the dimensions of 2,7 x 2,0 m. I wanted it a little bit bigger, about 3,5 x 3,0 m but, because the delivery time was stated to be about 4 weeks and october was at the end I had to act so I did buyed it.
     Fortunately they could store it until I was ready with the pier and the other parts so I wasn't forced to store it somewhere in garden or who knows where.
     After that, in the next day I started to dig the hole for the pier, At the end I sitting there having in front of  me a hole with a deep of 1 m and about 80 x 80 cm wide at bottom and 50 x 50 cm at surface.
     Because the construction is a light one I had to build a support frame. The entire construction is sitting on 6 cement cylinders 100 cm deep and with a diameter of 20 cm, I use this approach because, in case, the entire system can be relatively easy removed comparing with a full cement base.
     Total cost including motor, motor controller, tools, spare parts, small parts, lost parts ;-) is about 2.300 -2.500 euros (2.600 - 2.800 dollars),
     If someone is interested to build it, drop me a line, take care when you are mounting the roof, you have to reinforce it because it is this way separated from the main construction and it will lose stability.
     For remote control I use an IP Power switch with 4 outlets and the computer is set up to power on after power loss so till I get there most of the time the PC is already waiting for the user password
     The roof rolls on 6 stainless steel rolls, each capable to carry up to 200 kg,
     I will keep this topic updated with further information.

Take care

I tried to finish this object since some time but only managed to get the exposure time in the burst style. That means that per night I got 2-4 images till the clouds marched in and ruined my sessions.
So here it is, at least finished after over 3 months.

So, I have to do a bulk upload.. I have "ignored" my blog for some time, just had a lot of work to do with my house and job and and and.
The images are done from march to September this year and the stacks are from 20 to 45 single images each 900 seconds long.
Stacking have been done in DeepSkyStacker (the last beta version) with some aggressive values set for sigma-kappa clipping and it seams that I am close to the optimal setting for stacking narrow-band images.
Post-processing done in Photoshop.

Enjoy the images and apologies for not tagging (yet) my images ;-)

I just got an email from
The Horsehead and The Flame image will be tomorrow between 11 and 12 AM set as front (main) image when you will navigate to that page.
Oh boy, Im so glad...

Take care friends

EDIT 15 of April.
It is there... about 900 views in 15 minutes

M81, M82 and IFN (Integrated Flux Nebula)

M81, M82 and IFN

Until now this one is the hardest  project done in team with Emil Pera.
In January he asked me - being done with the Rosetta Nebula - if I have some target insight, after my negative answer I got a "what about the IFN? what do you think about it?".
It was more than OK for me and because I'm that kind of person that believes only what I see, I ignored the notices found over Internet like "For IFN you need a good sky" and so on.
And here we are, after weeks of work, nights lost because I have used the wrong star to center and frame the objects (about 2 nights in fact) and some sweet words addressed to Lady Moon  (exposed 60x1200 sec exposures to realized that, in fact, for IFN you really need moonless nights) we managed to use 47,5 hours of data.

Emil Pera
4 minutes exposures summing 12 Hours
8" Newton F/3.3 with ASA reducer/corrector, EQ-6 mount, Canon 1000Da camera and TS OAG

On my side (LOL you can use the "And now, in the red corner, with a weight of....")
30 minutes exposure for H-alfa (6 nm Astrodon) total time 22,5 hours
20 minutes exposure for luminance (Astronomik CCD CLS filter) total time 13 hours
3,5" ED-APO F/5.5, EQ-6 mount, QHY9M camera at -30°C, guiding done with Celestron 102SLT and Atik 16ic

It seams that we have reached almost the magnitude 23 and that means that this image is the deepest till now. Also Unimap identified and located 163 galaxies.

NGC 2244 Rosetta Nebula in narrow-band  (Hubble palette)

Nope is not my birthday LOL but it seems to me that Emil Pera starts to enjoy the work on narrow-band images so a few days ago he send me the stack of my NB images used in our project. So (drumming sound) here it is m baby :-) looks good to me!
The processing is done in the Hubble palette, I'm at hospital now so in a few days I hope to do a version using the CFHT (Canadian-France-Hawaii Telescope) palette, in that case the Nebula will be mostly read.

 It seems to me that in the middle of this nebula there is a second one, it looks like a planetary nebula to me but I'm not the expert in this area.  It is also visible on the image from the Nasa Sky Survey so is not sensor artifact or optical error
