A Sultry Evening...
One my favorite things to do... Watch a ominous lighting intense storm come over the horizon. With continuous cloud to cloud lightning & a few cloud to ground strikes. This was one of those perfect photogenic Nebraska storms.
Severe warned right after sunset. Found an open spot to shoot just some incredible June storm photography for 2022!

A regular Canon T3 and Sigma 28-70 Zoom F2.8/4 set at 70mm, F/4 was used to take 20 x 30 second images at ISO 3200 of the comet or about 10 minutes of exposure.
They were tracked with the camera mounted on the scope/mount I was using to take close-ups. I stacked them in IRIS and did some post processing in PS and here's a reduced display image that resulted.
Still pretty noisy with twilight, skyglow and LP, plus my darks were probably off. It's a project to redo over a weekend the way it looks now.

First crack at California Nebula with only 1hr of exposure, Canon T4i Modified Camera and Baader Moon & Skyglow filter.
Another first. Night doesn't really start here now until at least 10:30 (usually its midnight before I'll go to bed after telescoping) and frankly I was rather tired. Clear nights are not to be missed, so I went for it and ran the session completely unattended.
I automated things last summer, but never have set it up to start completely on its own. Something made me a bit nervous about it, like a completely self driving car. I got up the next morning , though, and it all went without a hitch. Gotta give credit to NINA's advanced sequencer.
Given the option I would prefer to just be outside, but on those nights where for some reason I can't be its a nice option to have.
(With the shortness of the night I decided to run lum only and use the color from last year)

Due notti in montagna PER sciare ma io pensavo innanzitutto a provare il setup light e grazie all'amico Alessandro che si è immolato per la causa, siamo stati un paio d'ore a -12°c venerdi notte, e ora orgoglione posso dire che il setup funziona bene :) ci vorrà piu integrazione, per questo scatto, rimedierò, mentre io ora sono a casa costipato che starnutisco :\ spero almeno di non avere sulla coscenza anche Alessandro influenzato..

Another surprisingly, to me anyway, small target. Even at 1214mm its rather small in the frame.
Luminance mostly from the Starfinder, color from the Edge.
On a different note... I noticed on the bottom of my Starfinder 8 mirror a handwritten indication of focal length (in inches- slightly "faster" than spec). It must have been made in the US near the end of US made Meade products, but beyond that there is something to an era where each mirror is inspected, measured, and marked individually. The Starfinder GEM series is much maligned, even by Ed Ting, and in all fairness much was pretty poor (like the mounting system, focuser, finder...), but I have yet to fully match the caliber of the optics. Even the nearly 30 year old mirror coatings are still in great shape.
I have one other similarly marked scope, a Star Instruments Rich Field 6", also US made (in the late 1970s )and also a superb performer. I don't think its the US made per se, but a different focus. There are many beautiful telescopes made today, but in general the philosophy has shifted to higher outputs. I can't imagine most scopes being inspected and measured by hand these days.

Barnard 142 and 143 with Aquila and other star clouds nearby.
120 minute exposure on TMax 400 4x5 sheet.
Taken at the Golden State Star Party 2023.
My notes say that I ran the shot at F6, but the coma in the corners suggest it may have been run wide open at F5.6. Picture taken last year on E100 shows better stars in the corners at F5.6 so I'm not sure what's going on here.
Streaks are likely from satellites, but at the late hour when it was taken they must be very high altitude to still catch the light.
There are some fibers on the film and a few scratches, too. Nothing too bad.
Developed in the Ecopro Xtol equivalent 1+1 dilution for 10:30. Negative looks good, skyglow is evident without being too much from the film fog.
I might try putting this on a contact frame and seeing what kind of a print I can make with it.
Scanned in Silverfast 9 at 6400 dpi, made a file too big for lightroom. Used an adjustment layer in Photoshop to improve the contrast a bit to darken the black clouds and bring up the star clouds. At this scan level, each pixel is 4.2 microns.
However, Lightroom can't import that size of a file, so it had to be downsampled to 25% to bring it over. Of course, to export it to Flickr is a further downsample to the long edge of 4000 pixels. At full size viewable on Flickr, the resolution is 31 microns per pixel.

A long, long time ago, a star exploded in a supernova, and what we see is all that's left of it: gas clouds drifting apart until one day, a long long time from now, they will have dissipated
back into the void.
This is the Cygnus Loop, including the Veil Nebula.
Imaged over four separate nights, totaling five hours and 47 minutes of data, from my balcony in "basically downtown" Montreal.

The Crab Nebula and Zeta Tauri in a 2.5 degree wide field image. Taken under a bright urban, Bortle 6-7, sky in Austin, Texas on 2021-03-04 04:35 UT. WO RedCat 51 250mm f/4.9 telescope, Baader skyglow filter, cooled ZWO ASI 533MC Pro one shot color camera.
Total exposure of 69 minutes with 3 minute subs. Processed in PixInsight, Topaz DeNoise, and Photoshop.
This used much of last year's data, but everything else started over again so is posted as "new".
I ran 3 (albiet shorter) nights of Ha this round and I can't really tell much improvement past maybe 10 hours. Smooth? Yes. Noiseless? Yeah, not much noise when you intergrate 700 subs from a cooled camera. Detail and depth? Not really. Maybe if I ran different data- Oiii, or Sii, but a point would come where the effectiveness of more subs becomes questionable.
Is it possible to get more from more data? Perhaps, but iMHO a person's seeing, light pollution, and gear is only going to give so much detail and depth.
I was just too lazy to put in accurate dates for all the data, so listed in as either Ha or OSC.

Other features in frame are NGC4217, NGC4226, NGC4231, NGC4232, NGC4248. It is located in the constellation Canes Venatici, about 25 million light-years away from Earth.

Processing:
• Register the NB and BB masters
• Split channels of NB - keep only the red - relabel ha
• Split channels of BB - keep all three - relabel red, green, blue
• Remove Stars from ha image, no need to create star image
• Open ha starless, Open Pixel Math to create new image-
• ((ha*85)-(red*5))/(85-5)
• Where 5 is the bandwidth of filter
• Rename new_ha
• Make a clone of new_ha
• Open STF clip the shadows to really isolate the ha nebula
• Open HT move STF to HT and apply to new_ha_clone
• Use Range Selection to create a mask in order to protect the red
• Open red channel and apply the mask
• Open Pixel Math to add ha to red
• $T+(new_ha-Med(new_ha))*8
• Replace target image
• Put together channel into RGB
• SPCC
• BTX and NTX and STX un-screen
• Stretch starless, curves on saturation and small rgb/k s-curve, unsharp mask
• Stretch stars, curves on saturation
• Take starless to Photoshop ACR contrast, highlights, black level, watermark

Not sure if the green in the image is noise or skyglow. I like to think it is skyglow

On the road close to Peggy's Cove, Nova Scotia. I would have liked more frames, and a better foreground image, but after about 5 frames the lens and all my gear was covered in dew. The mosquitos didn't help either. This location is not all that dark but it is possible to capture the Milky Way in some detail. There is a bit of red and green skyglow as well. Five frames, median stacked, iOptron SkyGuider Pro.
Col du Bavella (1200m s.l.m.), Corse du Sud
Se fosse stato per il popolo Corso, a cui ho chiesto più volte un posto buio per potermi attrezzare e fare fotografie, questa foto NON sarebbe mai stata scattata :) mi spiace dirlo ma è un vero dispiacere vedere una cosi' bella isola popolata da gente così poco sensibile. Venite a trovarmi in Italia e vi concio per le feste ;)

I can't thank the people of Corse, I asked several times and gently a dark place to and to be able to take astrophotos, this picture doesn't would never have been taken! I'm sorry to say but it is a real disappointment to see such a 'beautiful island" populated by people so insensitive. Come and see me in Italy and we settle for the holidays ;)
