TIS DMK23U274 via 2x Barlow lens on Coronado PST on Celestron CG-4 with motor.
Mosaic of seven plates, each 25% of 600 frames taken at 1/200 per frame, Gain 1,79 dB.
Capturing software: TIS IC Capture.
Datasets were stacked in Autostakkert!2 with dark and bag-flat, white reference point added in PS*, images were deconvolved in AstraImage 3.0 (Richardson-Lucy algorithm, 0,3 pixels, 9 iterations) and piece-meal stitched in MS ICE**. Complete image was wavelet-sharpened in AstraImage 3.0 (1-10-15-5-1) and touched-up in PS again.
*One of them is still here, near the bottom left corner.
**MS ICE can stitch the whole set at once, but it does it rough and dirty. Stitching panel-by-panel - say 1+2, when summ+3, when 4+5+6+7, when summ+summ -creates far more better final product.

Exposures: about 65/100
Processing: movie was processed in Autostakkert!2. Resulting image was subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Cauchy type PSF, size 1 units, 8 iterations). Deconvolved images were stitched in Microsoft ICE.
High-pass filtering was made in Photoshop. Image was scaled down to 75% of original size to "tighten" the features and get the target value of 2,5 pixels per 3,5".
Note: I continue to think about why color cameras show better performance in solar imaging in H-alpha giving the possibility to capture prominences and the "surface" details in one exposure? My idea is that it's a result of in-camera de-Bayering process gone wrong. Green channel normally defines the overall luminostiy, but in monochromatic image, such is that is produced by H-alpha telescope there is no green and the luminocity (or should that be "luminance") is restored incorrectly to the benefit of the photographer, nonetheless :)
High resolution, 4 panel mosaic of the full moon taken with a Canon 7D through my Celestron C8. Each panel is a stack of 50 of the best images from 95 original photos of each of the 4 hemispheres of the moon. Pre-processed in PIPP for basic alignment and quality analysis, then ran a Photoshop batch action to crop, stacked in AutoStakkert! 2, Lucy-Richardson deconvolution and wavelet sharpening in AstraImage 3 SI then stitched together and post processed in Photoshop CC.
Lunar Mosaic from Florida on 01-08-2017. 9 individual panels stitched together with MS ICE. Each panel is a capture of 1,000 frames and the best 20% stacked in Autostakkert!2. Wavelets processed in Registax6. Finalized in CS5. Captured with a Celestron C6 (1500mm F10) and ZWO ASI178MC CMOS camera (6.4MP).
To the lower centre is the crater Plato (109km) with its smooth floored interior, Rimae Plato can be seen winding its way off from its North Western edge.
Below are the Montes Tenerife and Montes Recti mountain ranges as well as a number of large peaks Mons Pito and Mons Piton.
The Vallis Alpes cuts an impressive valley off to the west itself has a rille running along its length, it’s just about visible.
Was the valley caused by an asteroid impact, volcanic activity or by some other means?

TIS DMK23U274 on Coronado PST on Celestron CG-4 with motor.
Clumsy blend of two datasets of 25% of 600 frames taken with 1/500 and 1/293 seconds per frame. Stacked in Autostakkert!2, deconvolved and wavelet-sharpened in AstraImage 3.0, aligned and blended in PS.
Note: need extra technical details? Feel free to ask ;)
Tech note: I have found out that in deconvolution (at least that of Richardson-Lucy type) AstraImage tends to saturate image to untolerable extent. Since I keep my historgram near 90-95% saturation, it is a big problem. It can be solved by adding say 9 pixels of pure 65536 in the corner of the image to trick the programm. Works fine!
Janssen is an interesting system of craters in the southeastern quadrant of the Moon. As the Sun sets on this dramatic scene, many interesting features can be seen in the contrasting shadows and sunlit portions of the terrain.
The largest crater, encompassing many other features, is Janssen. It is a well-worn, shallow and ancient crater. The second largest crater in the scene, Fabricius, is located almost entirely within Janssen's outer wall. In addition to several other craters, Rimae Janssen is visible on Janssen's floor.

My 2nd hand skyprodigy was £150 supplied with the wrong handset.Ipurchased a starsence hand set for £25 from ebay(I was lucky with that one.).The handset socket on my telescope proved to be faulty but plugging the hand set into the aux port works fine.The mount does not track very accurately and I always get out of shape stars when I try long exposure.The canon 70D was a gift to replace a 550d I had bought 2nd hand for £200 including a 70-300 lens.
Gibbous Moon - 100% crop from 16 stacked subexposures (best 16 out of 360)
Image Scale = 0.44 arc-second/pixel
Date: 2011/11/21 - 19:04 to 19:57 EST
Exposure: mixture of 1/250 sec at ISO 200 and 1/125 at ISO 100
Telescope: Celestron EdgeHd 800 -- approx 2000mm at f/10
Camera : unmodified Canon T2i = 550D
Mount: Astro-Physics AP900 -- rough polar alignment (no drift alignment)
Processing:
1) Focusing via EOS utility live view, exposures made from live view mode (EFSC active, so no mirror slap or first shutter curtain shake?). Three individually focused sequences were done. Two were at ISO 200 and one at ISO 100. The Feathertouch motorized focuser was moved 20 or 25 steps between groups of about 25 shots at each focuser position. The total range in each sequence was about 75-80 steps between closest focus and farthest. The hope was that some of the shots in each sequence were near optimal focus, and these would be selected later by stacking software.
2) 16 best of 360 individual shots selected, centered and cropped to 4400 x 3000 using Planetary Imaging PreProcessor (PIPP).
3) These 16 shots were split 9 ways in a 3x3 grid (with overlap), into 1800 by 1200 pixel panes using Photoshop CS5, since neither Registax nor AutoStakkert 2 would handle the large 4400 x 3000 frames. (Zerene stacker PMAX mode could handle them, but the output was not good.)
4) The 16 sub-shots in each of the 9 panes was passed to Registax for stacking, using 50% drizzle, yielding one 3600 x 2400 output stack for each of the 9 panes. "Wavelets" processing was done on each pane, using the same settings. These setings were far from optimal, since the whole wavelets thing is a mystery to me.
5) The 9 panes were then combined into a mosaic using Auto Pano Pro 2.
6) Photoshop was used to expand the canvas size to 9600 x 7200, convert to gray scale, adjust the levels, do 90 degree rotation, and then reduce the image size to 4800 x 3600 (100% crop of the original shots from the T2i). JPEG conversion was done with quality = 10.

The Sun was very interesting this morning. My personal fave is a long thin filament encircling the sunspot AR 2106. But I also like the obvious spiralling patterns around 2109, 2108 and 2111.
So it just happenend very good for firstlighting my new QHY5L-IIm camera :D

Exposures: about 60-100 out of 120-200 from three movies (I let the Sun drift across the field of view at different "latitudes")
Processing: three resulting movies were processed in Autostakkert!2. Resulting image was subjected to Richardson-Lucy deconvolution in AstraImage 3.0 (Cauchy type PSF, size 2 units, 6 iterations). Deconvolved images were stitched in Microsoft ICE.
High-pass filtering was made in Photoshop.
Note 1: A bit of simple math now.
The solar disk is 1800 arcseconds wide and fits in 977 pixels on this image.
Optical resolution of PST is
Rd = 140/40 = 3,5"
This means that the Sun contains 1800/3,5 = 514 resolvable units. Reileigh resolution in this combo is achieved then the solar disk's size becomes larger than 1028 pix. Very good value is 1466 which is 1,5x extra magnification or 600 mm effective focal length. Using 2x Barlow lens will go up to 1954 pix which is a bit too much, but since I have such a lens it can be tried instantly :)
Mars 20th Dec 2024(23:00 UT) , fairly good seeing conditions, although the Jetstream was over the UK. This image consists of 4 images de rotated in Winjupos, each image used the best 1,000 frames from each 11,000 frame AVI. Captured using Firecapture V2.7, Processed using Autostakkert V4, Registax V6 and Winjupos. Equipment used, Celestron C14 Edge HD, CGEPRO Mount, ZWO ASI224MC camera, Carl Zeiss 2X Barlow , No ADC.
This is a six image panorama using a 36 year old, multiple owner, 8-inch SCT. I flocked the interior of the scope and cleaned the optics the best I could. In the process, I discovered that the secondary mirror needs re-silvering. The primary mirror looks in good shape. The collector looks OK too, though given multiple owners who probably removed it like I did, who knows how it is aligned. Despite all that, not a bad image given the seeing was poor, the moon was only about 30-degrees above the horizon, and my collimation skills need practice.
