I like the BRT, when there’s no trailing the images are deep and I can measure down to the 16th magnitude or so. The major drawback is, I would say, that the telescope is severely oversubscribed. I’ve been off BRT for quite some time, instead using iTelescopes 4 and 5, but now I’ve resubscribed. My old account was of a type that don’t exist anymore, and instead I opted for the 3 pounds per month type of account, which lets you have ten images in the queue.
Three pounds per month leads to a quite cheap price per image compared to iTelescope and SierraStars, provided those images gets taken. Wonder how long it takes before those ten images gets through …
