#Venus R-NUV false color

Nice
God I wish I could do Venus, house blocks my scopes view of the western sky.
colours are good for 8 inch sct.. good job

I am waiting on the Celestron x-cel 3x barlow to come in the mail. Super excited to get in closer on the planets!
maybe if youve got a nice celestron with a juicy focal length. I dont
I am gonna check right now
resolution with a 3x barlow with my current scope is 0.25"/pixel
literally haha, still cant wait to get in closer. I have a 3x barlow already but its poor quality and creates hideous chromatic abberation.
A filter that only lets UV light in? no not yet but I do have an IR filter I think its like 7nm or something.
Yeah I am aware of that with venus at least. Its also good for Jupiter as well
Would I just substitude my UV/IR cut filter for this filter and shoot normally or would I have to do something similar to mono deep sky where I have to combine different colour channels manually in post?
Yeah, I dont have that either, so would a filter for a OSC camera have any beneficial effect or no?
it would be weird
Yeah but I am happy with that because its how it would look to us right? Its cool to have the detail but I connect better to astrophotography in pure broadband visual because its how we see the universe.
As long as I can resolve the planet I am happy. ALSO
I have an ADC and I couldnt get it to work properly with my scope. I would correct the colour fringing, but the image would be blurry and I couldnt figure out why
I now suspect that the ADC requires at focal ratio of at least f/10 so all light rays hitting it are parallel. My system only gets to f/8 with my 2x barlow.
thats interesting because it conflicts with things Ive read. Here what do you think about this? https://skyinspector.co.uk/atm-dispersion-corrector-adc/
it states they work best with higher f/ratio systems.
okay, so what could be my issue then, is there back focus?
yeah I definitely dont use it at f/4, only with a barlow
What I have observed at least with a test with jupiter is when the adc is in place and oriented to line up with the horizon I can see colour fringing. I adjust the glass sliders equally until the fringing disappears. The focused planet is still significantly blurry. I take the adc out and focus and its noticeably clearer and more resolved then with it.
brand new
Ive used it 3 times
You dont use an adc for venus? its so low on the horizon
so you shot this during the day while venus was overhead?
interesting... I dont have buildings like that to block the sun, but I do have an observatory roof I can move around.
How can you find it in the day light sky? your go to is that accurate?
Crazy Ive tried to slew to venus during the day, but I can never find it
ohh is that the UV blocking one?
I am going to probably buy this then
neat. Ill have to experiment more with why my ADC is not working. The next thing I am going to try is back focus distance.
I am polar aligned, my system is on a pier
it is but I cant seem to differentiate between the planet and the sky.
what camera settings did you use and how did you process everything? @cedar karma
im a bit late
i want to try again with venus
I see, thanks a lot
I’m planning to shoot Venus in a few days again
My collimation is good now
Do you think I should go without a barlow? I heard you need higher f ratios for nuv
