Leo Triplet (M66 Group). This LRGB image (L=11 images 600s 1×1 binning; only 1 image each of RGB 300s 2×2 binning all @-36C using AG12 and QSI683. Calibrated with darks and flats in Maxim DL. Combined in Maxim, stretched in … Continue reading →

I concentrated on getting lots of H-Alpha data and limited OIII and SII frames. The following images are taken from 300s subs at 2×2 binning (low gain) with a QSI683 at -36C. 21 x H-alpha frames and 5 frames each for … Continue reading →

I tried a number of combinations with a Televue x2.5 and x5 barlow lens with and without an Atronomik IR pass filter (742 nm filter that passes light longer than this wavelength). The visible part of the spectrum is more … Continue reading →

21-02-2015 H-Alpha, O-III, S-II Astronomik filters. AG12 and QSI683, 12 x 300 sec images at 2×2 binning (low gain). Guided with Lodestar And with slightly more emphasis on the red channel…    

The bright star at the top of the picture is Alnitak – the left hand star of the 3 stars in Orion’s belt. LRGB image created using the AG12 and QSI 683 taken on 22-01-2015 x9 Luminance @1×1 bin 600s … Continue reading →

LRGB image. AG12, QSI 683. Sub-frames: 6xRed; 7xGreen; 7xBlue; 13xLuminance all 2×2 binned. Luminance 10 minutes, colours 5 minutes. Calibrated and stacked in MaximDL, levels and curves and high pass filter applied in Photoshop.  

M33. All images 2×2 binning. 19 x luminance 600s and 7 each of RGB images at 300s. Aligned and calibrated in Maxim DL and digital development applied to each LRGB image. The images were then batch converted in Maxim to … Continue reading →

DMK with Astronomik RGB filters. Green filter yielded the brightest image by far. From 1500 frames only the best 30 or so were kept from each colour channel for stacking in Registax 6. Linked wavelets used to process each image which … Continue reading →

NGC 281 is an H II region in the constellation of Cassiopeia and part of the Perseus Spiral Arm. 21x240s subs at 1×1 binning in hydrogen alpha (luminance and red channel), 16x90s subs at 2×2 binning in OIII and SII. The … Continue reading →
