Observing Report with TERRIBLE viewing conditions!

#1

Post by jrkirkham »


We had visiting guests last week. They were friends from Arizona who had never been in the Midwest. We gave them several "firsts". We set out trail cams. We went off-roading with a 4x4 and side by side. We visited museums and a cave. We took the boat out and flew in a small plane. We even went mushrooming. We did just about everything a person could do in May in downstate Illinois EXCEPT take a peep through the telescope. :Astronomer1:

They really had their hearts set on looking through the telescope. But Illinois in the spring being Illinois in the spring, there were no stars to be seen. For most of the week we couldn't even see the sun. I don't know what transparency you call it when you can't identify the sun. On the morning of their last day the sun came out. That was nature's cruel mockery. :twisted:

But the sky was clear and we decided it worth a try so at 2:00 p.m. we decided to try for something, anything. :observatory: We opened the dome, fired up the C11 and told it to aim at the moon. We found it, but the sky was too bright to get many details. After fumbling around with several filters we settled on the red filter at 40x magnification. They were amazed! It was their first view. They saw craters and learned to use the controls. Then, just to see what we could see we swung the telescope around to Venus. I was nothing but a dot in the sky, but again they were amazed at what could be seen on a sunny day in the middle of the afternoon.

They had to leave to catch their flight at 4:00 so we didn't have much time. As we closed everything up and headed out one of them told me how glad he was that we got to look through the telescope. He had wanted to all week, but thought he would not get to see through it. It turned out to be a great observing session in the middle of the afternoon on a sunny day in May. :dance:

Hi Rob. A great report on daytime astronomy viewing and it looks like you did a great outreach as well as having an overall fun time with your guests. I find that for daytime lunar viewing the Wratten #15 deep yellow filter with 67% transmission factor (also called minus blue) is best to darken the sky and increase lunar surface feature contrast for best observing results. Thanks for your report along with the great included photograph Rob and congratulations on receiving the TSS VROD Award today.

Suboptimal? :joking:
