Tonight I'm heading to Pensacola Beach for a club outreach event.  I hope to grab M83, Omega Centauri and Centauri A.  Also check in on SN2022HRS.

Here's some of this month's objects from last night (first session in 3 months according to the synscan hand controller...).

 

These are with my 8" f/4 Newt + ASI 290mm + filters, live combined LRGB. Most details on the captures apart from binning (all 2 x 2) and gain (200). Moderate seeing, partial moon.

Hi,
A simple little M82. I had fun taking it using the Optolong night sky filter which is passing from 650nm and in the near infrared ( 650nm - 1000nm). More near IR than visible in this image.
Software: sharpcap pro
130/650 PDS Skywatcher + EQM35
QHY 290M cooled and gain 198
Exposure : 57 frames x 20s -> 1140s
Sky : Bortle 8

finally got a chance to do some EAA last night and worked on the list a bit.  Tried to get M83 but it was behind the trees.  still having a problem getting this setup to focus properly so things still are soft.

 

info for the images:

c9.25 at f10 on cgx
zwo uv/ir cut filter
gain of 400
asi294mcpro
darks applied
SC 4, CPWI, NINA

spectacular globular.  i looked at this one in my c11 last weekend visually for the first time too and it is dazziling! slight crop

Hygiea

 

I had about an hour spare last night and thought, as a final challenge, I would try for Hygiea.

 

Hygiea was relatively easy to locate.  It was positioned amongst a scattering of readily identified stars, making it easy to find.

 

I started out thinking I would simply leave SharpCap live stacking the star field for the hour and see if Hygiea's motion was evident. Frames were 2 seconds each and a gain of 400, dark subtracted. Scope was Vixen ED103S and camera an ASI385.

 

For some reason that escapes me now given I am nice and warm again, I started regularly pausing the stack for short periods after the first 50 frames were stacked. That is, stack 50 frames, pause and let 50 frames drop and then repeat. Slight elongation became apparent after about 20 minutes of exposure.

 

The final stack attached is 827 X 2 second frames with the last frame stacked 56 minutes after the first frame.

 

The motion is ready apparent over the 56 minutes. If clear tonight, I'll try for a single image to confirm Hygiea's motion over the 24 hours.

Southern Pinwheel. About 4 mins exposure. Had a nice long stack going and then the live stacking crashed so missed out on posting a longer EAA exposure. Having some mount challenges as have had to move my scope placement due to renovations and haven't quite got it set up properly.

 

C6 at 1000mm, asi462 bin2, gain 90, 10s subs

 

Light Stack 26frames  ASILive 10sec Bin2 20.1C gain90 2022 05 08 201648   M83   Southern Pinwheel
 
Hygiea was a lot easier than I expected, with the help of my eVscope. The movement is clearly visible.
 
eVscope 20220510 085744   Hygiea
 
I've been observing asteroids on multiple nights this week for the Unistellar Citizen Science programs and they move a heck of a lot faster than Hygiea - they move visibly with each 4s sub.

Picked these up in the middle of other things.

 

C8, GEM28, 0.63, ZWO 294MC, image scale 0.70"/px f/6.3 at 1280mm.  Clear, 68F, 10mph gust, swirl.  Use the 80cm dew strip for the first time.  The combination of swirling gusts, dew shield and big OTA caused issues at times.

 

Gain 350, mostly 15 or 45 x 20 secs.  Dark (75F) Flat.

NGC 7023 EAA taken a couple of nights ago with 6se, f/3.3, 385mc (3s exps using dark correction, 60min total exp, 400gain), cropped to remove majority of the vignetting and field rotation...

NGC 7023 (Snow Globe cluster) from a week and a half ago.  6se, f/6.3, 294mc with CLS filter (5s exp w/dark correction, 6 min total, 425 gain).  First time out with the 294mc and wasn't really looking too long at anything that night.  Has more vignetting than I was actually hoping for but also a whopping increase in fov over my 385mc.  (I really need to start using flats but they seem to be considerably more of a PITA to obtain over the simple darks)...

Hygiea 24 hours apart

 

There was lot of high level haze last night but I still managed a capture of Hygiea to show it's movement over 24 hours.

 

My 56 minute time lapse the night before - see my earlier post #39:
