A quick summary of the Palomar Observatory. Many thanks to CaptainCaustic and Palomarskyguy for helping set this up. It was greatly appreciated. www.youtube.com www.youtube.com The scope itself is intimidating impressive. You stand it Its Presence. Seeing the collage of technology was fascinating (from the smell of Victorian steam engines to the 8W laser used for the adaptive optics (along with actuators that twitch about 2000 times per second)). The dome itself also has a feel of Roman Empire Grandure. The building is beautiful and white. Thursday 23nd july Well, didnt really get up the dawn chorus broke out, and the light grew more full, and then I could see the high cloud that had ruined the seeing for the latter half of the night. No matter, both transits could clearly be seen, and Im pretty sure to meteor impact site too! (southern hemisphere) Packed up the scope and drove up to observatory. There by 7ish. Slept in car till they opened gates at 9ish. Had the observatory much to myself. And amazing place, got a vaguely greek feel to it. Very white, large buildings, tied up with the discovery of the unknown. Had a nose around myself, before trying to call the outreach guy. My phone struggled for signal, so I asked for help from one of the helps in the visitors center. The guys name was Scott. We got on well. Very much kindred spirits with an appreciation for what these great machines symbolize. The Palomar observatory is over 50 years old, but its mass has the feeling

Question by Scissorhead: How Do I get good insect macro’s with my sigma zoom lens?
Do I need a macro lens to get good macro shots? Iv got the sigma 70-300mm lens on my canon 1000D. Can I zoom in too get close up pictures of insects etc.. ?

Best answer:

Answer by casperskitty
You can shoot insects with a zoom lens. Just keep in mind that they aren’t going to have the look of a macro shot. In a macro shot you can often see tiny details in insects, like the proboscis of a butterfly, but you don’t get that kind of magnification with a zoom lens. Still, I have seem some amazing shots done with zoom lenses so just get out there and try. Just remember to use a fast enough shutter speed when using a long telephoto so that you don’t get camera shake.
