The North America Nebula (left) and Pelican Nebula (right) are one(!) large emission nebula in the constellation Cygnus.

The nebula appears four times the size of the full moon. It's real size is 50 light years in diameter - it's at a distance of 1800 light years from earth. It was "probably" discovered by William Herschel on October 24, 1786 - or by his son before 1933 (William Herschels notes weren't clear if he meant this particular nebula).

This is my first image with my new Officina Stellare Veloce RH200 scope and the 10Micron mount.

This image consists of almost 25 hours of data (3 hours Ha, 9 hours SII and almost 13 hours of OIII).

See https://mstriebeck-astrophotography.blogspot.com/2018/07/north-america-nebula.html for more details.

The Heart Nebula is at a distance of 7,500 light years from earth in the Perseus arm of our galaxy. It spans 200 lightyears! The nebula is ionized by the relatively young stars at the center of the nebula (their open star cluster is known as Melotte 15). The nebula is 150 arcminutes in size (the moon is 30 arcminutes!) in the constellation Casiopeia.
It was discovered by William Herschel on November 3rd 1787 (he first discovered the brightest part in the lower left - NGC 896).

See https://mstriebeck-astrophotography.blogspot.com/2018/05/heart-nebula-ic-1805.html for more details on taking the images and processing them.

The Heart Nebula - my first "real" mosaic (4 panels). 40 hours of integration time and a lot of work to equalizing the 4 panels. But it finally turned out well.

How do you tune your Lunt with a double stack?

I bought an LS80THa/DSII for my Lunt scope in the hope to get even more detail. How do you tune the two etalons? I know where my first tuner knob needs to be and adjust the second one until I have maximum contrast. But then I can even adjust the first one again ...

And finally: I have a PC-USB Pressure Tuner Controller for my Lunt Scope. Would I need to get a second one for the second tuner??!!

Thanks!

The North America Nebula is four times the size of the full moon (which demonstrates the HUGE field of view of the 55mm lens!!!) The nebula and the Pelican Nebula (the lower, smaller nebula) are part of the same interstellar cloud of ionized hydrogen - which is forming stars. Between the nebulae and us are dust lanes that create the shape. We don't know for sure how far the nebula is away from us and what its dimensions are. Some speculate that Deneb (the very bright star in the lower part of the image and one of the brightest stars in our skies) ionizes this nebula. which would put it at a distance of 1800 light years and a diameter of 100 light years!

This was the first image with my 55mm Pentax lens (https://mstriebeck-astrophotography.blogspot.com/2017/10/a-pentax-lens-based-imaging-rig.html)
