I've ignored our sister planet for far too long. When I was 9, after careful observation through my Sears catalog-sourced Tasco 11TR, I determined that Venus was "boring." While my intellectual interest in Venus has always been intact, it is not something I've bothered with visually since Milli Vanilli, Debbie Gibson, and Mötley Crüe were pumping out hits.
Now in 2018, I figure three decades is enough time to revisit my initial assessment. Maybe it had been a rash decision, made when the planet was too low as seen my from my grandmother's front sidewalk, or from our own front yard. Maybe I had reached that assessment because I did not have monochrome and color cameras and a laptop that could potentially tease out details in UV and IR. Actually, come to think of it, that is probably the reason for my initial assessment.
So, my cameras are a ASI224MC and a QHY5L-II-M. Word on the interwebs is I can manage with these two cameras, particularly the QHY5L-II-M in UV and the ASI224MC in IR. I know I'm missing some hardware. Namely I'll need a UV-pass filter. I have my eye on the Astrodon UVenus filter for that. For IR, I have the 850nm IR-pass filter by ZWO. The only filters I've ever used for planetary are UV/IR cut filters, so I'll assume the frame rates I'm used to will not apply. I have an ADC which my colorblind eyes are not really good at adjusting.
Will these two suffice? Are there other filters you would suggest?
Another question I have is in the barlow arena. Right now I have an old, trusty Celestron Ultima shorty, and Celestron X-Cel 2x and 3x barlows. I've read that the barlows will actually block UV, so mine might not work. Am I mistaken here? If not, are there barlows that will not block UV? Do I even need a barlow for Venus even though I might be undersampling without one? I'll be using F/10 SCTs.
Does anybody have any tips and pointers, hardware-related or otherwise? Are there best practices you've developed over time that you can share?
When it comes to imaging Venus, in terms of experience, I'm still that 9-year-old with a Tasco 11TR, so any advice you have will be most welcome. I'm all ears.
