Μιας και αυτές τις μέρες επιστρέφω στο Λονδίνο, σκέφτηκα να σας αφήσω με ένα αποχαιρετιστήριο δωράκι! Οι φετινές αστροβραδιές ήταν σίγουρα στα highlights του καλοκαιριού μου και θα μου λείψουν πολύ! Άντε και του χρόνου παιδιά Keep shooting!! SH2-155 Cave Nebula Wide Field Object:SH2-155 The Cave Nebula in Cepheus Type: Emission/Reflection/Dark nebula Constellation:Cepheus Distance: ~2400 Light Years Tech Specs: Location: Mount Parnonas - Greece Date: 6-7 August 2013 Scope: Officina Stellare Hyper APO 80 @ f4.8 FF/FR: Televue 0.8x Photo Reducer/Flattener Camera: QHY9 KAF8300 Mono Chip Temperature: -20 C Filters: Astronomik L-R-G-B Mount: Skywatcher NEQ6 PRO + EQMOD Guiding: QHY5 + Baader UV/IR Cut + PHD Capture: Nebulocity 3 Processing: Deep Sky Stacker, PixInsight, Photoshop Light Frames: L: 22x600sec Bin1x1 RGB: 6x600sec Bin1x1 Total: 6.5 hours Calibration Frames: 20x[Darks,Flats,Dark Flats,Bias] per channel Description: The Cave Nebula, Sh2-155 (or Caldwell 9), is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.

Εν όψει της επερχόμενης εξόρμησης στον Πάρνωνα, έφτιαξα άλλη μια από τον Αύγουστο... η περιοχή έχει πολύ ενδιαφέρον, έχει απ' 'ολα γενικά - φωτεινά, σκοτεινά, αμυδρά και αυτό το ασύλληπτο αστρικό πεδίο. Σκέτη απόλαυση στην επεξεργασία! Ελπίζω να σας αρέσει Objects: IC 5146 and Barnard 168 - The cocoon Emission/Reflection nebula and Barnard 168 Dark Nebula in Cygnus Type: Reflection/Emission/Dark Nebula Constellation : Cygnus Distance: ~4000 Light years Tech Specs: Location: Mount Parnonas - Greece Date: 3-4 August 2013 Scope: Officina Stellare Hyper APO 80 @ f4.8 FF/FR: Televue 0.8x Photo Reducer/Flattener Camera: QHY9 KAF8300 Mono Chip Temperature: -20 C Filters: Astronomik L-R-G-B Mount: Skywatcher NEQ6 PRO + EQMOD Guiding: QHY5 + Baader UV/IR Cut + PHD Capture: Nebulocity 3 Light Frames: L: 24x600sec Bin1x1 RGB: 12x300sec Bin2x2 Total: 7h Calibration Frames: 20x[Darks,Flats,Dark Flats,Bias] per channel Description: IC 5146 (also Caldwell 19, Sh 2-125, and the Cocoon Nebula) is a reflection/emission nebula and Caldwell object in the constellation Cygnus. IC 5146 refers specifically to the nebula and Collinder 470 to the star cluster. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39. The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years. When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.
