HI,
Thanx for your info.My present OS is Ubuntu 20.04 LTS. I tried Siril, but could not figure out how to get my RAW Sony .arw format files into it. I am using DigiKam and the learning curve is fairly steep, but I am making some headway. I downloaded WINE so I could run Windows version of PIPP for sorting the numerous exposures astro uses to get a final image. I have only used it once. DigiKam has a blend tool which looks like it stacks fotos or I can use RegisStax. I would prefer to use Siril or a Linux program instead of WINE. Do you know how to get Siril to deal with Sony RAW .arw files? I think Siril wanted SER format and I also downloaded FFMEG but gave up after a day of failures. I have used GIMP for basic cropping, scaling and exposure corrections. Also ran Mint18.1 Serena Cinnamon version on an old HP desktop some years back, but took the easy way and updated Ubu18.04 LTS to 20.04 on my laptop.
I woul like to get a workflow that consistently runs moon & planet RAW frames from start to finish. So far I have not been able to accomplish all that and any help much appreciated.

Thought this might interest you? Added 10kmAh battery to bottom via ¼-20 screw thru aluminum plate & into tripod mount hole + laser pointer in flash shoe via cushion cable clamp & a hot shoe mount.
Sadly cloudy skies since full moon so no fotos, yet.

Now that Jupiter/Saturn set w/ the sun I have turnd the Sony A6300 + 200-600 telly to the moon, sorta "point & shoot"!
Hopefully I can attach foto to this reply? This is the jpg, save by DigiKam as .png file, @600mm (900mm focal length w/1.5 crop factor) f 6.3, 1/500 ",ISO 100. It was handheld auto focus w/ lens & camera stabilizers On.

Is this topic open so fotos can be posted?

Thank you for the pronpt reply & answers to my questions. Looks like what I want. Went ahead & ordered. Thanx again.

I am looking for advice about laser pointers for astronomy.
1. Which is better red or green beam?
2. Range of beam from ground up into the nite? No chance of interfering w/ planes?
3. Power ? What size batteries?
4. Desireable specs?
5. Links, brands, venders?
TIA
My experience w/ Sony 200-600 telefoto lens, both fun & frustrating. Yes definitely the moon is a friend from zeroing in on infinity focus to easy to foto. The conjunction was more a challenge. At best was one frame of Saturn, fuzzy, w/its rings. I had lots of problems w/ camera tripod and definitely will invest in equitorial mount eventually.

I commute semi-annually twixt Colorado/Florida, having spent years in snow research I need not learn anything more bout snowflakes, one year USPS applied 8 of those yellow labels to a letter shortstopping it in Gainesville FL about 50 miles from my home & Commerce City about 60 miles from home in CO. When I peeled off the labels the postal clerk asked why I had not called my carrier, when I told him I didn't have his number as I had never thought to date him, he did not laugh.
I knew it pkg just arrived when I was on the head. Just dropped at door, even tho "signature required" AND guess what, it is Sony Video projector! Now Go figure that one..

Wow, ask questions & and you all supply informative answers & more. Thanx much bwana for the FOV Starry Night map, etc. I will ✓out that app.
Sadly the lens arrived in Florida at 3:45am plenty of time to drop it at my door, buTT instead it is going ro South Carolina, go figure! Tracking promises delivery by 9pm tomorrow.

Thank you all for your replys. I have little else to do these days other than bake bread & Bundt cakes modifying my Mom's recipes and dropping them off on neighbor's screen porches.
Yes I will start tonite weather permitting. My tripod is one I used to mount an 8x10 view camera on, fairly sturdy. Jupiter & Saturn as well as Mars were discs in my 8x42 Nikon binocs last night so I will see what the Sony lens produces .
Thanx again for the advice.

PS Any Linux OS folk out there, I use Ubuntu 18.04 and GIMP, that could save me time searching for stacking &/or other astro-processing software + tutorials on U-Tube and Google? I could not get RegiStax to download, but I need update Ubuntu to 20.04 and recheck download folder. TIA

My Sony 200-600mm f/5.6-6.3 Telefoto lens for full frame cameras arrives tomorrow and while I bought it mainly for pictures of birds I would like to use it to catch the close encounter of Jupiter/Saturn 21Dec20. On my Sony A6300 with a 1.5 crop factor it becomes a 35mm 300-900mm telefoto. Therein lies my first question-
1.Does the crop factor apply to the f-stop as far as light reaching the APS-C sensor? I think it would still be f5.6@ 300mm & f6.3@900mm but I am confused by what I have read online.
2.How do I calculate the angle of view for this internal zoom lens?
3. While I realize I will not get the same image size as I would using my C5Celestron (it is Colorado and I am cocooning in Florida) how can I approximate the size of each planet in the image?
4. I am new to astrofotos and with no experience in stacking and just basic skills using GIMP (crop, adjust exposure...) the Linux app, not PhotoShop. My OS is Ubuntu LTS 18.04. Any recommendations for compatible Stacking apps appreciated. I have searched U-Tube and found some videos that will help, but first 21Dec20 then processing tho I will set up tripod in back yard the first clear nite to take some shots, maybe a 4k movie, as I am sure the learning curve is steep.
TIA for any info, tips, help. Nice to have a new project at 86years old.

Once viewing some Weston beach nudes I moved closer & closer. Up close I discovered the model had goose bumps. The Pacific waters must have been quite chilly.

Years ago visiting Fallbrook CA in a house with a cupola a hummer guarded a feeder near the Northside breakfast nook driving off all comers. We solved that by hanging another feeder outside the Southside dining room window & poor hummer was exhausted clearing away intruders. Finally he compromised and we were kept busy making sugar solution.
