Canon 60D lenses. Found some and I'm looking for advice.
toxic replied to BogdanMD's topic in Getting Started With Imaging
i have used the stock 50mm f1.8 at f7.1 and the 70-300mm f4-5.6L at f5.6 and f7.1 for astro and they are great lenses - the Cassiopeia image was taken with the 50mm at f7.1 on the EOS 200D and orion with the 70-300 at F7.1 on the EOS 90D the reason for that f stop is for the stars to be round in the corners and that is all.and both used on the old star adventurer. -
Deep Sky Stacker stacking problem
toxic replied to Oisinmcc16's topic in Getting Started With Imaging
that is way to high you need to have it around 10% the lower the more stars it detects -
21st to 22nd from the back garden canon eos 90D with 70-300 f4/5.6L at 300mm on the star adventurer. Orion is 145 times 30 seconds exposures at iso 6400 and the horsehead is 57 times 30 second exposures at iso 6400.

How do I start imaging after i bought equipment
toxic replied to betelgeuseisreal's topic in Getting Started With Imaging
just put a lens on the camera and put it on a tripod focus on a bright object (the moon) and take some short exposures of around 3 to 5 seconds (not of the moon them exposures would be too long and iso too high) with a 50mm lens at iso 1600 to 3200 and take lots of them in raw file format then stack them with deep sky stacker ,for the moon you would need iso 100 and exposure time around 250th to 500th of a second as a test hope this helps. -
yes the aperture is the size of the mirror or front element of the telescope and can not be altered by the camera only by physically putting something in front of the lens/mirror so it collects less light by say putting a scope cover on with a hole in it.
-
you will not be able to change the aperture on the camera as your scope has no iris/aperture blades the only things you can control on the camera are - ISO - CAPTURE TIME .

hi i use the Microsoft lifecam 300 hd with a home made adapter to the 9x50 finder (remove webcam lens attach 35mm film canister to front of webcam housing dont forget to cut the bottom of the canister off lol and unscrew back from finder and added a home made tube to it with a 1.25 inch hole to fit the film canister or eye piece) and its still going strong even on the 250 quattro S and thats since 2011 no need to change what works.

yes but if you think about it it isnt actually a longer interval time it is also counting down the exposure time as well
