Unistellar eVscope 30 minutes of the Eastern Veil Nebula, in Bortle 9, central city, with the Baader UHC with IR block 1.25" filter installed, from July 9/10 - 2021.

 

Here is the target straight out of the eyepiece:

A few more recents above from July EAA mostly in Bortle 9, with the Unistellar eVscope, from my backyard.

It's a fun scope to take out for a whirl, set up and cover a lot of ground from the city.

 

An underrated favorite of mine with the eVscope, STE1:

Got a Skywatcher AZ GTe for my little Equinox 80 doublet.  Also grabbed an L-Pro and an L-Enhance filter.  Some samples from first light with this setup.  These are 40 second snaps with my Mallincam DS10c.

My perennial take on M16, while it's still visible from my balcony.

 

I'm testing things these days, and especially NIR (near infrared) imaging from the city, inspired by Satoru Takagi's incredible images. I acquired an Astronomik ProPlanet 642 filter, that blocks everything but deep red (H alpha) and infrared up to 850-ish nm. There's little signal left to play with, but it's valuable signal, with far less light pollution. The technique doesn't apply to all objects, but it may also work on (some) galaxies...

 

This is a 24-minute livestack, using 60s exposures, guided (EvoGuide50ED, 183MC). My C6 was sitting on its Evolution mount and wedge. The optical train comprised the Starizona SCT Reducer IV (so I'm running around f/8), the aforementioned filter, and my ASI294MM Pro in 11Mpix mode. Pretty pleased with the detail I get at such a wavelength. Interestingly, the famous "Pillars" are much more transparent in infrared than in the usual observations made in visible light. Those Pillars harbor newly created stars that essentially glow in deep red and IR. I was also pleased to see detail in the so-called "Black pillar" on the right, a large spiraling piece of gas

M51 ALL Stack 356frames 2848s annotated

 

Looking out for details! - IC 4263, NGC 5169, NGC 5173, NGC 5198
targetting M51 and put all concentration to get a good image of the big whirlpool galaxy, first I didn't realize that I shot some interesting companions within the same photo. More and detailed annotated image can been seen with astrometry.net My personal favourites are:

IC4263 - Is an Edge-On galaxy, Distance 38,3 Mpc | 125 mio. Lightyears
NGC5169 - Is a spiral galaxy with bar, Distance 34,3 Mpc | 112 mio. Lightyears
NGC 5173 - Is an eliptical galaxy, typ E1, Distance 34,1 Mpc | 111 mio. Lightyears
NGC 5198 -Is an eliptical galaxy, typ E1, Distance 35,7 Mpc | 116 mio. Lightyears

 

This four objects looks interesting to me to might have a closer look for them. Of course to do this a telescope with a much higher focal length will be needed. I have to think about, what future will make it possibly.

Great “cluster of galaxies” capture.  I might try some of these with my Evo 8 at F/7, or even F/10.

This budget setup is perfect for summer nebulae. As alphatripleplus posted earlier, despite being an achromat the ST80 produces surprisingly nice EAA views when used with an H-Alpha filter. The filter reduces halos around stars and enhances details on emission nebulae. Even with the filter the integration times are fairly short, usually 250 sec.

Date/Time: July 30th  10PM-1AM

Location:  Bortle ~5 Driveway MA,
Scope: Bresser 208mm F3.9 with SW Quattro coma Corrector, UVIR filter
Camera: ASI294MC-Pro, 370Gain, 0°C, FOV 1.35°x0.92° @ 1.18"/px
Software: SharpCap for Darks, Flats, Livestacking and Stretching, RAWTherapee for cropping and resizing
System: Beelink X55 J5005 8GB mini PC with remote desktop over dedicated WiFi

 

I took a break from astronomy for a while, of course when I try to get back into it, it's nothing but rain and smoke for a month. Last night was clear so I set up and live stacked for a couple hours. I spent most of the time looking at the July EAA challenge objects, but I did check out some other stuff. 

 

M14 4.0s X 59 = 236s

gallery_280529_12251_173817.jpg

I was looking at other globulars like M92, M15, M13 prior to checking out M14. I was immediately taken by it's deep orange color. Most of the other globs I was looking at had a lot of blue stars in the mix (blue stragglers) but M14 was purely orange.

 

NGC5907 4.0s X 123 = 492s

gallery_280529_12251_91213.jpg

I usually check the picture preview in Cart du Ceil when I'm surfing around for a new target. For whatever reason NGC5907 did not have a preview. I was VERY pleasantly surprised to find such a spectacular and large edge-on spiral galaxy with loads of granular detail. I'm glad I didn't skip over this one.

 

NGC6633 4.0s X 45 = 180s

gallery_280529_12251_79861.jpg

This was a nice loose and scrappy open cluster, I really like how the UV-IR filter presents the subtle star colors

 

NGC6709 4.0s X 41 = 164s

gallery_280529_12251_5360.jpg

This cluster was a little more populated, and appeared fuller for it. I like the pair of yellow stars, for whatever reason I see them as wide-set eyes on a squat creature.  The surrounding star field was incredibly rich. 

 

 

Last night I noticed a lot of satellites on my digital finder scope, so I recorded the frames and strung them together into a short clip this morning.

(Rising Cam IMX290 Mono + 5mm F1.4 IR Corrected CS lens)

 

You can see how useful the digital finder scope is for navigating around all my trees with the remote EAA system. It's also great for cloud dodging and sucker hole chasing.

Like the poster above, I have had nothing but smoke filled skies and constant rain for the last few months. I think the last time I was out was in Late march.

 

I also have added a digital E-Finder (ASI290MM Mini) to my rig. It allows me to star hop to objects because the goto function of my new scope is not as precise as I am used to. It also keeps me informed about local sky conditions, like clouds, satellites and of course, clouds.

 

I received my new telescope, an Orion XX14g telescope on Wednesday last week and have been dying to get out and use it. Friday night and last night were nearly ideal for some EAA astronomy. I also received my new ZWO ASI533MC Pro camera about a month ago and wanted to try both out. Here are my results:

 

Gain was between 120 and 340, different gains for different objects. Exposure times were also between 2 sec and 8 sec, depending on the object and the lightness of the sky background and elevation of the object in question. Binning was kept to 2x2 for each object. The TEC cooler was kept off for these pictures.

I think I've viewed M16 and M17 enough this season, but decided to take one more look at these two last night. Set-up was an AT72EDII reduced to f/4.4, ASI290MM mini mono, gain 300, no binning and SharpCap Pro 4.0. This time I used my ancient Lumicon Deep Sky Filter, instead of no filter or H-alpha.  7 minutes total exposure for M16 and 6 minutes for M17.

 

(I got tired of  difficulties with using ASILive in very rich star fields, as it seems the live stacking alignment algorithm gets overwhelmed by too many stars and frequently reports " Can't find matching triangles", but has no problems in less star rich fields. No such issues with SharpCap.)

I just got back from an incredible night ever EAA Imaging. Although the dew was horrendous, my Orion XX14g dripping with water, I garnered 9 planetary nebula, using my new ASI533MC Pro camera and L-eNhance filter and a 2x barlow making for an F/9.2 focal ratio.

 

Before and then after my secondary dewed up, in which I attached a dew strip to warm it up, I got some great results with my scope/camera setup.

 

Here are my results. I should point out that the XX14g has a lot to be desired with its goto pointing system. I used an ASI290MM Mini as an E-finder to help me locate these elusive objects by star hopping after the scope got me in the general area.

Here is my favorite image of July. It is summertime and planetary nebulae are plentiful! It was hard to pick my favorite but this one won out because of how different and difficult it was to image.

 

 

Minkowsku2-9, Butterfly Nebula, is magnitude 14.6 and a size of .7x.2 arcminutes and at 32 degrees altitude. I was really surprised that I was able to make out the lobes.

 

 

Equipment

  • Celestron 8” SCT  on Celestron Advanced VX mount
  • ZWO ASI294MC
  • Celestron F6.3 focal reducer
  • Optolong LPro filter
  • Darks/Flats applied
  • Offset 10, binning of 1
  • Bortle 7 (red zone). Seeing ok.
  • Live Stacked.  Screen Saved (Cropped and Resized)
