I need to drive to a dark spot, which is not such a problem, since I own a VW Caddy Furgon. It's something I dream of, but unfortunately I live in a light polluted area. Also, are you fond of some other accessories, like filters, binoviewers, etc? And when I do have some spare time, like this weekend, it's raining out of buckets! Just frustrating! I'm an owner of a start-up company and working practically 24/7. The much bigger problem is lack of free time. It's therefore easy for me to move a 12" dobsonian. It's such a great overview! Once I get a bigger scope it will be my starting point in choosing new stars for my observation program.įurthermore, your garden-shed-observatory is just great! It's something I dream of, but unfortunately I live in a light polluted area. It was a great pleasure to read through your website, especially the descriptions of different VS categories and your favorite stars from each category. 28,637 submitted visual estimations, the first one made in 1971! I wasn't even born back then! I'm just happy to have this opportunity to learn something from you. I'm real excited about your input, since it came from such an experienced visual VS observer. I'd say that, unless you are doing CCD stuff, anything near 8" aperture is out. Add to that the possibility of background illumination (faint, but 'there' nonetheless) from the highly-plentiful external galaxies in these areas For example, the fields around EM Cyg and TZ Per look much darker (and thus better contrast) than, say, R Leo which is a long way from the galactic plane where the dark nebulae are. But getting to know the sky is a profound pleasure, not a job, so good luck with that!Īlso, certain parts of the sky seem to give better results, probably due to the background. You do need to know the sky very well for this, since you will be finding everything 'manually'. I also used to have a 6" refractor and got to about 13.5 with that, so in terms of faintness, go for the dob, despite the ancillary problems like realuminising every 5 years or so. I am in a small village with no light pollution, and my faintest mag so far is 16.5, but usually I get to about 14.5-15. I use a 14" dob, and the limiting mag relies heavily on sky conditions. Limiting mag depends on so many variables (sorry!). I would be grateful for any kind of advice or shared experience. Or maybe an 8" SCT? Is someone using a similar scope? What are advantages and disadvantages of the different scopes regarding VS observing? Is coma a problem with the bigger reflectors? Or CA with the fast F5 6" refractors? Of course, a 6" refractor is also an alluring option, since I know how good my own refractor is performing. How deep can I go with the 12" reflector? 14-15 mag? I would like to add some CV to my observing list. I would very much like to hear the opinion of experienced visual observers regarding their favorite aperture and setup. So far I am thinking of getting the GSO/Revelation 12" F5 dobsonian. However, I am looking for an additional bigger scope, also suitable for visual VS estimation. It's a great low budget scope and I love estimating variable stars from the binocular list. I am a proud owner of a small Skywatcher 80mm F5 refractor and have been using it for almost a year now.
