Galaxy M100 !
Distance: 60 million light years
This was the last of three targets I had on my last night out. I have already posted the other two results. So, here is this one.
From my backyard here in Las Cruces - portable setup. For the curious, I have also recently updated my "Equipment" page on my website talking about the new hardware, here: http://jeffjastro.com/equip/

AP1100 GTO
ATS Portable Pier
QSI 690wsg
14x5mins Lum, 3x5min ea RGB

Updated --- my Astronomy page
Hi all: I have updated my astronomy page's "equipment" area to include a couple of pics of my new telescope and new mount.
I think it is accurate to say: This new equipment has been my dream - dream to go after very deep sky and difficult targets. In particular, my personal favorite of galaxies. The new scope and mount did not disappoint, and you can see the results of course further down in my blog with this new setup.
Here is a direct link to my equipment page on my astronomy site (check it out!): https://jeffjastro.com/equip
Here I am including a screenshot preview of the page:

NGC 3389 --- 72 million light years away!
Hi all,
Here is the second target of three targets I had on 21 May 2025 from my backyard here in Las Cruces.
Main target here for me was NGC 3389 (the spiral galaxy with "structure")... also seen here is NGC 3384 and just out of the frame is M105 (you can see part of it at the bottom of the frame).
NGC 3389 is about 72 million light years away --- and FURTHER way than the other two by roughly 20-30 million light years!
There are about a dozen or more total galaxies that were picked up in this shot...and you can see the many different structures of those very distant galaxies.

Cygnus area - widefield!
Not published here before - captured this last Summer.
Cygnus area (wide view) --- Deneb, Vega, and Altair are in the view, as is the North American Nebula (and others).
Look at all those stars...
Canon T3i DSLR, Samyang 14mm lens, iso800, 18x5min exposures --- 5min exposures (yes!) thanks to the SkyWatcher SA 2i w/EQ base.
