Hi everyone, First time poster here. I plan on moving back to Singapore after spending decades overseas. I have pretty good astro equipment (Tak and Astro-Physics stuff) and would sell them if astro-photography is not possible in Bortle 8 to 9 skies. I'm sure I have to modify what I do when I'm in ...

Thanks, good to know that. On ZWO website, it says that "For ASI183/ASI1600/ASI294/ASI533 cameras, the heat emitting from the TEC will be conducted to the camera case and avoid any dew problems when TEC cooling system is working." so it seems to be working. I only know Player-One cameras a...

Hi all,

I just like to ask around owners of cooled ZWO cameras. Which cooled ZWO camera absolutely does not dew up in Singapore? I am just thinking if the ZWO camera window dew heater feature really works or not for us.

Hi guys, Just a quick bump by including this link to a CCD filter calculator: https://astronomy.tools/calculators/ccd_filter_size In this way, you can calculate if 1.25" filters work for your system. For example, a Redcat 51 with 183 camera and a filter-sensor distance of 28mm, is roughly the l...

Hi guys, I found another thing to let go and this is the hardly used 3x Televue barlow. Nowadays, the planetary cameras have small pixels so I don't need the 3x barlow to reach the optimal sampling. At the very edges of the field lens of the barlow, there are some smudges which I also don't know why...

No worries! Thanks for looking around here.

Hello... EQ3 mount modified to AZ. Would it fit the Vixen SXG-S71 tripod? I have MIA so long already - lost touch with all the info. If it can fit - can have a photo ? Thanks Hi, Since the Vixen SXG-S71 tripod fits GP2 mount then it should fit EQ3. The "modification" of EQ3 that I did is ...
