This was shortly after (I think) some work to improve the collimation on the Ritchey-Chretien. I don’t know why I didn’t concentrate on a single target, but I jumped around from several last March, so once again I have mediocre data on all. Object M65, M66, NGC 3628 Camera ASI1600MM-Pro, Luminance Only Lens/Scope AstroTech RC6 …

And if that title wasn’t enough to pull you in… The seeing in Brooklyn is always bad. I’m on a flight path to LaGuardian. So 3-arcsec is typical. And did I mention I’m in Brooklyn, NY? So the light pollution is always bad. Which make star clusters reasonable targets. Object M36, Open Cluster Camera ASI1600MM-Pro, …

I subscribed to Adam Block’s online tutorials and have been working my way through them. It’s a long, slow process. He’s incredibly thorough, sometimes painfully so, though I supposed that’s better than the opposite (skimming over things so fast you can’t follow along). So while I’m nowhere near finished with the tutorials, naturally I had …

This was a “filler” project; I was setting up to image further east, an object that was still below the horizon, but had time to kill and realized that M33 and the core of the rather small Triangulum constellation would fill the frame of my Canon T6i with the 85mm Rokinon lens. So, why not? …

It was the end of the night really, and as the Earth rotated, my real target had moved behind the neighboring apartment, but the night was still dark (well, as dark as it gets is Brooklyn, which is not very), so I pointed to the Rosette as a good target for imaging with the narrowband …

So…a while back I dropped my AstroTech RC6.  That was a very sad day. It landed partially on the USB plug for the filter wheel which destroyed the jack. I had to desolder the jack and solder in a new one (which now works again, yay!). But the scope itself took a hit and was …

It wasn’t a very clear night, and this was a back-up target for the not-so-transparent skies. I had planned to take a set of images testing the procedure for doing a mosaic. Around 9pm, the sky looked decent with hints of the Milky Way overhead. Unfortunately, that didn’t last. So instead of a mosaic, I …

This year our troop went to Ten Mile River (Camp Aquehonga) twice. It’s a long tale and I’ll spare you. I normally help out and co-teach the Astronomy merit badge class but during our second week (actual week 4 of the camp), attendance was very light and no one had signed up for the classes. …

This was really an equipment test after replacing the Dec motor on my CEM25. But before I called it quits, I decided to do a single 120 second cropped exposure using my ASI2600MC on the RedCat 51. No calibration frames, just some denoising in PixInsight to get a pretty picture.
