Removal of the focal reducer, addition of the Revelation x2 Barlow , et voila, F20 SCT!
Tryin gto get to grips with focussing, plus not really sure how much 'seeing' changes. Targets so far are Saturn, Jupiter and Sunspots.
Imaging using Sharpcap, around 1000 frames/2 minutes of avi, then using Autostakkart /Registax.
Jupiter, with Io just coming into view at the top, with the shadow of Io right on the top edge.
30 odd mins of L and around 10 each of RGB
Ten thousand years ago, before the dawn of recorded human history, a new light must suddenly have appeared in the night sky and faded after a few weeks. Today we know this light was an exploding star and record the colorful expanding cloud as the Veil Nebula. Pictured above is the west end of the Veil Nebula known technically as NGC 6960, but less formally as the Witch's Broom Nebula. The rampaging gas gains its colors by impacting and exciting existing nearby gas.
I left the telescope collecting images of M15 to try and improve on the earlier picture. When I went to turn it off just around midnight, I saw that Jupiter was no visible. So, 2000 frames in L, 1000 in each of R,G and B. Processed in Registax and combined in Photoshop.
It looks like the Great Red Spot is just visible on the lower edge.
The Eagle Nebula, now with 23 mins in R,G and B and 60 in L.
What with the loss of night and then murky weather, this is the first image I have collected in months. Based on 11 mins L (!) and single frames of R and G and two frames of B.
The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula and The Spire) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of the Milky Way.
