Thank you for your kind words. Hope your interest in seeing the planets gets re-kindled and you fulfill that goal

Thank you for the kind words. Yes. We can see the moons of Jupiter and Saturn. In the planet pictures post, I have marked these moons in the Jupiter-Saturn conjunction.

Thank you for the kind words.
1. A refractor per se is not an absolute necessity, but preferred. Reflectors due to their construction - primary mirror reflecting into secondary mirror can suffer from coma distortions which will need collimation. Refractors are usually quite robust.
Before choosing a telescope, the better approach is to understand what is the goal. Do you want to do visual astronomy or photography. Are you interested in deep space objects or planets? The telescope will have to be chosen based on this goal.
2. For Milky Way, you mainly need a wide lenses like a 14mm or 18mm and a camera that has good noise performance. Just shoot single exposures of 15 to 30 seconds at a high ISO (this is where noise performance is important), and you should get the Milky Way. But I have also seen people shooting multiple frames with a 50mm lens and then stitching them using software.

Thank you for the kind words.
1. For light pollution, there are light pollution filters that block light rays emitted by city lights and pass light spectrum emitted by celestial objects. I use a filter called L-Pro made by a company Optolong. There are many other brands as well like Baader, Astronomik etc. that make very good filters. As I personally don't have the problem of city air pollution, I don't have enough knowledge on how people deal with this issue.
2. With a focal length of 480mm, I am sure the telescope can be used for day light photography as well. But it is too heavy and not sure if it will be agile enough to move the setup to track a bird that may be very active. I haven't tried this.

You must be burning a lot of midnight oil, hope your family approves. I basically hate spooky places and going far from the madding crowd and light pollution means also security risk of getting mugged by lumpen elements unless you travel in a group of fellow enthusiasts. |
Thank you for the kind words. This hobby does need burning some midnight oil. In visual astronomy, this cannot be avoided. But photography has its advantage here. I am working on automating the setup in such a way that once I set it up in the evening, I can enter a sequence of targets and the times to shoot these targets and the setup should automatically execute this. That way, I will have all the exposures ready in the morning. I have been successful in getting this for a single target. I started the sequence at 9PM and went to sleep. I had 90 exposures in the morning. Am working on getting this done for multiple targets.
Regarding dark sites, the camps usually are done in some place with security. The first event I attended in Bangalore was in a farm stay in Chiguru. The recent Coorg meet up was in a small home stay near Talacauvery. I think people do travel alone to lonely places. But I have not ventured into this yet.
