M27 first use of H-Alfa

I could image this object for a few clear nights. After all summer travelling and garden work, I could finally do some imaging again. This was not only the first use of an H-Alfa filter narrowband, but also new equipment: I switched laptops, so needed to re-install all software and needed to get all hardware working on it. That took me two hours. Also an Starlight Express automated filter wheel, and a Pegasusastro Focuscube were used for the first time.

M27 63x120s Ha only

I have some issues getting all the Ha detail (the internal structure and the outer halo) also visible in the color RGB combination.

Moon and also M27 on September 1th

The sky was not very transparent, and also during the weeknd the public lighting remains on all night. So conditions could be better.

I pictured M27, the famous Dumbell nebula, first with the Esprit120/Nikon D750. 19 shots of 300 seconds on ISO400.  Second target later during the night was Luna. I made a mozaic of 8 seperate pictures, composed from 60 seconds of AVI. Also here the Esprit was used ( I forgot to take the C11 out for cooling)  with the ASI 174MM in infrared and a 2x Barlow.
