It was cloudy for long time.
This night was clear, but moon was shining. I wanted to test lower iso value, than before, and I think it is much better.

M20 - Triffid Nebula - Take 2
A new shot of the Triffid Nebula. This was taken previously on my D200 and my D800 but this is the first time some real exposure length allowed the picture to show the full colour range of this beautiful nebula.
Taken on a Celestron C8 with a QHY10 at f/6.3. Total integrated exposure is 3hr50min with 5min subs.
Celestron CGEM 925 with Orion 80mm ED riding piggyback. Losmandy dovetail and rings for the guide scope. ADM knobs (much better than stock BTW). Two extra 11lb counterweights to balance everything (50lbs total counterweight). Also shown is a William Optics dual-speed SCT Crayford focuser, Meade 2" dielectric diagonal, an Orion 17mm Stratus eyepiece, and an AstroZap aluminum dew shield.
Rear view Close up of my C8 and Accessories used for imaging (see notes on image). Here are the details on the equipment I currently use for imaging:
- C8 with XLT coatings thru which all my imaging is done.
- CGEM mount rated at 40lbs but currently only loaded with about 24lbs of equipment
- Semi-Perm pier allowing me to keep the scope store safely in the garage but easily transport out to the deck while maintaining highly accurate polar alignment.
- 5mw green laser for quickly targeting objects. Also works well in combination with binoculars to target dim objects and to show visitors what they are looking at in the night sky.
- Heater for the 5mw green laser - need a temp range between 50 and 90 degrees for laser to work, so in the winter this is a necessity.
- 9x50 finder user as a normal finder
- 9x50 finder used as a 200mm guidescope
- DMK21au04as camera used for Lunar/Planetary imaging thru filters and as a guide camera
- ATIK 314E Mono camera for DSO imaging thru filters

Five years ago this past Thursday on June 10, 2016 I took an early retirement after being a scientist, engineer & programmer for IBM, et al., for nearly 35 years (if one can consider 35 years 'early' of course ;) ). So it was quite serendipitous that on the morning of June 10, 2021 there was to be a solar eclipse visible at sunrise from parts of the world, including here in the Northeast US.
Knowing that any chance of seeing it would, as usual, not only depend on the weather, but also being at a location with a very low northeastern horizon, my friend Rick & I decided to try to catch it from his lake house in PA where we knew, weather permitting, objects would be visible above the tree line on the far shore within a few minutes after their 'theoretical' rise-time.
As the designated date approached, and with the weather forecast improving day by day; we arrive the previous afternoon, as we BBQ'd that evening and used compasses to determined the exact point on the far shore's horizon where the Sun would rise, we were entertained by one of the bald eagles that lives at their lake as it would fly low over the water, taking sudden dives and grazing the surface with it's talons in an effort to collect fish for it's own dinner.
Keeping an eye on the sky that night, and by this time seeing only thin cirrus clouds present, we started to setup our equipment about 2 hours before sunrise. As dawn approached we were greeted with a beautiful deep red eastern skyline, indicative that we might indeed be able to witness this wonderful event and much to our delight, just prior to the sunrise a gorgeous solar pillar began to appear and reflect off the water's surface.
Rising already in eclipse, due to the 'moon illusion' the Sun's crescent appeared HUGE ! - silhouetting the tree line on the far shore. Our calculations the previous evening proved beneficial, as within seconds we were viewing it through the optics we had decided to use for our attempt to image the event.
Therefore, please find attached a composite showing how it appeared (at bottom) through an Orion ED80T CF (i.e. an 80MM, f/6 carbon-fiber triplet apochromatic refractor) with a
commercial Kendrick 'white-light' solar filter connected to a 0.8X Televue field flattener / focal reducer and an unmodded Canon 700D (t5i) DSLR. Having an 80mm, f/5 Celestron 'short-tube' refractor piggybacked on the apo. that I usually just use for guiding, as can be seen at the top of the composite we also connected an ASI290MC 'planetary camera' at it's prime focus, and with a homemade 'white-light' Baader (visual grade material) 'over-the-aperture' solar filter, proceeded to take short video clips as we rotated through luminance, ultraviolet, infrared and methane filters while both scopes tracked the Sun using an Orion SkyView Pro goto mount. Simultaneously we utilized a William Optic's Redcat and Baader solar filter material with a Nikon D7500 DSLR on a Star Adventurer mount, but have yet to process and compile those shots.
With the high cirrus, at times the Sun's appearance reminded us of Jupiter or Neptune with their distinctive clouds belts. And much to our surprise, while viewing the eclipse at '1X' through pairs of Lunt solar eclipse glasses we had gotten for use at the 2017 Total Solar Eclipse we traveled to Idaho for; whether due to those same thin cirrus clouds or simply just attributable to 'averted imagination' & 'optical delusion' ;) , it seemed that one could make out the outline of the Moon's 'opposite limb' (i.e. that which was not silhouetted against the Sun) - almost like one would see with a thin lunar crescent (sans the Earthshine), or in computer simulations that show both the Sun & Moon's full disks. It was a wonderful morning with sights I will never forget!
Travelling to Hawaii for the Total Solar Eclipse in 1991 & to Idaho for the 2017 mentioned above, it was the third solar eclipse I was fortunate to witness with Rick, and we are currently making our 'plan of attack' for the upcoming TSE in 2024.
Hoping others also got a chance to enjoy this unique sunrise event - and as 'eclipsophiles' are fond of saying -
'May you walk in the shadow of the Moon' :) .
This is a wall-mounted sodium lamp luminaire around 150 meters away, as captured with a webcam at prime focus of my little Celestron 102SLT refractor telescope. No lens or eyepiece used here.
Field of view is about a third of a degree wide.
This is effectively 660 mm, f/6.5, 1/30 s exposure, dark overcast midafternoon.
Celestron C8@f/6.3+ZWO ASI 1600MM cooled at -20°C.
Total integration of 20 min. in 3x3 binning mode.
I decided to buy the Celestron Travel Scope 70 as an introduction to owning a telescope, as I was getting a little frustrated with my Celestron Skymaster 15x70 binoculars, which are a real bargain but of course there is no way of using higher power eyepieces and it can sometimes be awkward looking at certain objects in the sky with binoculars, so a telescope offered the option of using higher or lower power eyepieces and more comfortable viewing angles.
The first thing I did was buy an inexpensive star diagonal by Antares, although there is nothing wrong with the 45 degree prism that comes with the Celestron Travel Scope 70; I use it the most often. I got the star diagonal because in some situations it can be awkward looking through an eyepiece with a 45 degree prism, for instance when looking at an object very high up in the sky, the same with binoculars. The star diagonal definitely improved the viewing angle as it is 90 degrees rather than 45 degrees, it is also supposed to improve the amount of light reaching the eye, as it is essentially just a single mirror inside, but there didn’t seem to be a hugely noticeable improvement, just a lot more comfortable viewing angle. However, a star diagonal might not be a good idea for a complete beginner, as the image is reversed left to right, having the image the right way round can definitely make things easier to start with when you are learning your way around the sky, which is why binoculars are such a good idea to start observing with.
The bad points; the 10mm eyepiece is not the best quality, but it’s usually the higher power eyepieces that come with budget telescopes that seem to need upgrading the most. Having said that, this lens did provide me with my first detailed view of Jupiter, a couple of bands were visible, albeit at a significant stretch; they were just about visible. Being somewhat of a beginner when it comes to telescopes, I don’t have a lot of experience with eyepieces, although I have a lot more experience with camera lenses, the 10mm reminds me of some of the cheap and cheerful camera lenses made in Russia, i.e. almost sharp in the middle and an a big drop off in quality towards the edges!
I later acquired a 9mm eyepiece by TMB Optical to replace the 10mm that came with the Travel Scope, the performance was certainly improved; the detail of Jupiter was much clearer, but I wasn’t bowled over, telescopes such as this are reputedly not suited to high power eyepieces, I’ve read other users of this telescope who say it is more suited to medium to low power rather than high power, which I would definitely agree with, as the telescope really is a joy to use at low power, especially when using my Celestron 32mm Plossl.
This was the first eyepiece I bought and the second addition to the kit after the star diagonal. I would definitely recommend getting a low power eyepiece to go with this telescope. 32mm gives an exit pupil of 6.4mm with f/5 telescopes such as this and you can definitely see more with this eyepiece than the 20mm that comes with the Travel Scope; for example; the Beehive Cluster, Collinder 70 in Orion and the cluster of stars around Mirphak really jump out at you. One of the main reasons I bought the 32mm however was to find objects before using a higher power eyepiece, as the finder scope on this telescope is not that great to be honest.
The screws that hold the finder scope in place are not that helpful at aligning the finder and it never seems to settle where I want it to settle, which can be frustrating. And then looking through the finder does not help that much; it is rather dim indeed; it’s okay as long as there is a very bright star to use as a guide, although even Sirius can look very faint! It is not a problem when roughly framing a bright star and then looking through the 32mm, as the 32mm gives a wider angle view than the 20mm, so again; I’d recommend getting a lower power eyepiece.
The 20mm eyepiece that comes with the telescope is not bad, it is a certainly nicer to use than the 10mm, although medium power eyepieces are reputedly not as demanding as the higher power eyepieces. I will definitely not shy away from using the 20mm if the situation requires it.
One thing to take into consideration is that there is no Barlow lens included to increase the focal length of the telescope (800mm with a 2x Barlow and 1200mm with a 3x Barlow), which is probably a blessing in disguise, because if a Barlow was included it would more than likely be of the cheap and cheerful variety, just like the 10mm eyepiece, which is not a good thing, because from what I’ve read from other astronomers on online forums; using a cheap Barlow would just result in poor quality results (sounds obviously really) and beginners should not be dissuaded from pursuing astronomy by using low quality products, I had first hand experience of this as a kid. So I would recommend investing in a decent high power eyepiece to upgrade the 10mm and a Barlow lens, which doesn’t have to cost the Earth (or any other planet for that matter), but as they say; “Buy cheap; buy twice”.
One bugbear is the tripod, as many other reviewers have stated; it is flimsy, but it is of course very portable, the whole package being based on the idea of being highly portable; everything fits into the small backpack provided. Carrying along a sturdier tripod in a case on my other shoulder would not be an issue for me personally and the provided tripod would certainly come in handy if something happened to my main one.
Most importantly, when you put the minor bugbears to one side, what you have at the heart of it is a nicely compact sized telescope of decent quality that you can add bits onto in order to make improvements to the performance, e.g. a good quality eyepiece or two, a star diagonal, a better finder scope or red dot finder, a better tripod etc, these accessories would also be used in the future if/when a bigger and better telescope is acquired. For under £60 the Celestron Travel Scope 70 package is great value for money as a beginner’s telescope, even when ignoring the recommendations I made to improve things it will still have someone outside observing the sky with it every time there is a clear night, as this is what I have been doing! The only thing I have wanted was a bigger aperture; which is certainly not a bad thing for a beginner because it inspires us to pursue the interest further by getting a larger instrument in the future.

Taken with a Celestron C5 Telescope (White Tube, 1992-1996?) with a Hirsch T-Adaptor & Vivitar T-Ring on a Canon 7d. The Celestron was mounted to a tripod, and the photo was taken at the same location as the other photos in the earlier Lens Comparison set.
This photo is Straight Out Of the Camera- no processing was applied. (No crop or sharpening, to demonstrate the Telescope's true image quality) I also used a wireless trigger - but there were some considerable winds shaking the telescope as I took this.
