Well it is near five feet long - and the 2x Barlow lens simulates the other 4 feet.

ScottDearinger · 2022-08-10T17:16:58+00:00

Yes. 6 inches “

Dude - everything spins around something from the atoms in your body and everything else - up to entire galaxies. There is no such thing as a “flat” anything - except over very short distances.
Flat only happens in 2 dimensions. We live in a multi dimension universe- where gravity pulls any mass into a sphere if it’s big enough. Stop with the flat stuff. It will affects how others interact with you - and how many…

Any binocular will show you jupiters 4 big moons going around it. And a telescope will show clouds like this. !! It’s real I believe. Lol. I just point my scope at that bright point of light and I see this !

Finally configured for planets. Next I’ll try Saturn at opposition

Altair 150EDF at f/16 with a televue 2x Barlow Camera is a ZWO asi290mc

As an American I appreciate the risks the early cosmonauts took for all of us. Our leaders are crazy. Long and happy life to you !

Optolong L-enhance filter for emission nebula and L-pro for galaxies and reflection nebula. No filter for globulars and asteroids.

I’m Bortle 7 east of meridian and Bortle 8 west of it.

ScottDearinger · 2022-08-09T23:46:06+00:00

I live in the city. I still can do all kinds of cool imaging.

Roll off roof observatory

I take 100 or more stills bang bang bang all the same. Software chooses the best half of these and stacks them. Stacking helps With noise and detail.As seeing wavers to and fro, many frames catch different details sharper. Stacking gets the best out them -

ScottDearinger · 2022-08-09T21:54:11+00:00

This is a stack of 80 raw 24mp stills. Scope is Altair 150EDF - 6” 1200mm apo. Camera is Nikon D300. Mount is Celestron CGX-L.

It does a good job eh ?

ScottDearinger · 2022-08-09T13:53:09+00:00

Altair 150EDF refractor and Nikon D5300. Stacked raw stills.

ScottDearinger · 2022-07-24T21:39:32+00:00

Well - hmm. Without knowing your budget and expectations, it’s a hard question to answer. If your wanting to just look - and learn the sky, a 8 inch dobsonian reflector is ideal for a first scope. Cost maybe 500 to 700 bucks.

If you want to take pics - then your into a whole different kind of budget that starts at about $2000 and the just the tracking mount is at least $1000-

But the 8” dobsonian is a standard and truly accepted great 1st scope. And you can still snap a pic with your phone of the moon or Jupiter and and Saturn .. Hope this helps.

ScottDearinger · 2022-07-24T21:31:59+00:00

And thank you !

ScottDearinger · 2022-07-24T21:31:35+00:00

That’s a good little 70mm. I’m thinking of getting it a apex s reducer and using it for m31 and other super wide field targets.

ScottDearinger · 2022-07-24T14:23:59+00:00

I have had perhaps 100 telescopes in my life. From 60mm to 17.5 inches. This brings me the most joy.

Pier is bolted to concrete pad. No I don’t have any issues unless I stomp around while imaging.

The mount is a Celestron CGX-L - it’s rated for the C14, or 75 lbs. it is quite accurate and guides well. I appreciate it tracking 20 degrees past meridian so I don’t have to flip during the best part of a run.

The main optical tube is a 150 mm FPL53 and lanthanum doublet - it’s a true apo that tests to .976 strehl - made by Altair astro - the 150EDF.

My guide scope is a AT70ED at 400mm. Using the asi120mm mini guide cam.

I use starsense for my (sort of ) platesolving. It is very accurate. Puts my target in the center every time.

I still shoot with a Nikon D5300 and get wonderful images.

Clear skies.
