  1. First attempt and first clear morning after 2 weeks of bad astrophotography weather. Taken about 2 hrs before sunrise on 07/13/2020 The image still has some startrails from the comet stacking mode in DSS. I've used the comet stacking mode and normal stacking mode and blended both together in Photoshop to get the comet with its starfield rather than startrails. Difficult process to do this manually. If someone knows a method/software that does comet stacking with its starfield, please let me know. DSS failed me on several occasions using comet+star stacking method. K

  3. I've just realised that I have just passed my 15th year of membership of the Stargazers Lounge. I joined on the 28th of November 2005. This was my 1st post https://stargazerslounge.com/topic/1422-its-nice-to-be-here/ I'd just like to say a big THANK YOU to First Light Optics, the admins and the moderators for creating and maintaining this amazing place and also to all the members here who have helped me, put up with me, replied to my posts, been polite when I've (often) been mistaken, joined in when I've been excited about something and generally made this forum the most importa

  5. Martin's retirement is almost upon us. His last day at FLO will be Tuesday 25th. Martin joined us 11 years ago and has focused his attention almost exclusively on service and support. He is a people-person. His empathy, amicability and interest in others (not to mention his wit!) has made him popular with colleagues, customers and suppliers. If you have emailed FLO then there is a good chance you will have spoken with Martin. We will miss him. Though a sad time for us we wish him and his wife, Ann (also retiring), a happy, healthy, well-deserved retirement. Alex, Andy,

  6. The Witches Head Nebula, I'm not entirely sure I like this process. I was imaging late in the season and quite low down in the muck..I found this one of the trickiest images to Process .I thought I'd post it anyway. I may revisit it next season.. Imaged with the 105 f1.4 Sigma lens and ASI2600MC. 120s exposures a total of nearly 4 and a half hours. Processed with Pixinsight and Photoshop. Thanks for looking Peter Shah

  7. Hi, hope everyone's keeping well. I got lucky on Thursday and Friday night with some of the best conditions for imaging I've seen in months and with no plan in place I decided to go for the Horsehead. Whenever I image something I try to learn a little about the target and to my surprise It's not that clear who discovered this nebula. It is believed Herschel may have been the first to observe it in 1811 but his descriptions are vague. Edward Charles Pickering had photographic plates of the area which were cataloged in 1888 by Williamina Fleming who had previously been his maid and was then hire

  9. Sales of astronomy equipment during the pandemic continue to be significantly higher than normal while manufactures struggle with materials shortages and fewer shipping channels. Obtaining reliable ETAs from manufacturers and distributors is understandably very difficult. Even when they do have an ETA, it often changes overnight and it is not unusual for entire shipments to sell out before they dock. We believe this perfect storm will continue at least until a vaccine is found and made readily available so, with this in mind, we have made some changes at FLO that we want to share w

This is important because it underpins the way SGL is constructed and moderated. What is SGL? SGL is a positive, safe, friendly online community where you can discuss all things astronomy with like-minded people. Whether you are beginner or professional, visual astronomer or astrophotographer, armchair astronomer or cosmologist. SGL is for you. SGL is not Facebook.

High haze effected some of the data but the weather in Spain hasn't been at its best.

  12. This is 3.5 hours of data with the RASA 8 and ASI2600MC (105 x 2 min at gain 100, -10°C) on a NEQ6. There is apparently quite a bit of dust around M45 that I have not noticed before. I am pleased to see how deep this telescope/camera combination can go in a few hours. A dark site (Bortle 2-3) helps of course. Stacked in PI and mainly processed in PS, as usual. EDIT: I now added a second version of the image, inspired by Olly's reprocessing of his data, where I have sharpened the image more (mainly HiPass filtering and LCE in PS), getting closer to the limit of what the data can support.

  15. Blast from the past. 2 years ago, when I got the Samyang 135mm f2 lens, I couldn't wait for the winter to come so I can shoot Orion widefield. Well I did shoot it but I forgot about the data and 2 days ago when I decided to redo some of my 135mm work I stumbled upon this untouched data and I went to work Details and full resolution on my astrobin account https://www.astrobin.com/5i2906/?nc=user Emil

  16. Hi guys It took 9 nights between late August and early October, but I finally got enough data to complete the big mosaic of the Cygnus area i'd been wanting to do for ages. In a rare period of good weather, at one point there were 4 clear nights in a period of less than a week. Suffice to say, that was a rough week and by the end of it i was barely hanging by a thread due to the lack of sleep! I'm committing the cardinal sin here of posting late at night after spending hrs of processing (for about the 3rd night in a row) but i think it's finally time to stop looking at it and just p

  18. These 32 panels from a full frame camera were captured by Yves Van den Broek (VdB on SGL) using his remote rig based here at my place. He stacked the frames and put them into APP, which made a good job of the mosaic geometry but not of the blending. He then gave me the files so I slightly altered the geometry of the APP mosaic to reduce the need for final cropping and then processed the 32 subs. I used the modified APP mosaic as a template in Registar, where I combined the subs over a few days. Further post processing was done in Ps with some existing data, including my Squid Nebula, added f

  19. The Epsilon finally arrived on Wednesday after a much anticipated wait, I had a nervous couple of days when DHL delivered the rings but there was no sign of the scope. This is a new design with a new corrector and a primary mirror holder the same as the 180. Unbelievably it arrived collimated perfectly and rotating the focuser doesn't change collimation, something I never managed to achieve with my previous Epsilons. Setup was very straight forward as the spacing is the same as the 130. I needed to have a bracket made up to allow connection between the tube rings and the dovetail. I went

  20. What Can I Expect to See? By Way of Introduction It’s a very easy mistake to make. You see those spectacular images of colour and shape which show the beauty of the Universe and just how fortunate you are to live within it and you think to yourself, perhaps a telescope will show me something similar? Time passes and one day you hear about some astronomical phenomenon that’s going to occur. You’ve read the reports in newspapers and seen something on TV about the breath taking sights in the superlative that will appear in the night sky. So you decide to ask about what telescope you should buy an

Well, not 35 consecutive days of Mars images, rather images of Mars over 35 days/5 weeks where we continue our attempt to create a series of "disk maps" as opposed to "projection maps" that are more common, certainly insofar as annotated hi-res ones are concerned that can be used as "ready-reckoners" to determines specific Mars regions & place names. Some maps have the same features annotated, but only where said features appear on adjacent maps to help "reference" positions etc. We posted the first of these maps some time ago from the September 13th imaging session - here are th

  22. I received the Esprit100 back in June, but then had to wait for the focal reducer to come into stock, I didn't want to simply use the recommended flattener as one of the reasons I bought this scope was because I wanted faster optics as I have been thoroughly spoilt with the Samyang lens. The Esprit is f5.5 and with the TS Optics TS PHOTOLINE 2 79x reducer, this brings it down to f 4.34.Anyway, the image:Atik460EX and Esprit100 + TS Optics TS PHOTOLINE 2 79x reducerHEQ5POD dome had to be taken off the walls onto the dome table as the target was at the Zenith, so also had to wait for the wind t

  24. This is my 4 panel mosaic of the HH region, in H-alpha, taken over the past couple of weeks. A total of 66000 seconds of integration. I removed the stars in Starnet+ and there are some artefacts remaining. Not sure where to go from here - possibly some RGB data or Oiii/Sii. I can really only get about 4 hours on this per night because of the dual rig. Pre and post meridian flip, one telescopes view is blocked by the bottom of the dome slit. With four panels, it's a long slog only getting one hour per panel per night. Thanks for looking Adam.

This season just ending has been an unmitigated disaster weather wise and I have just been through my saved images and I have managed just 11 images this season and two of those were widefield nearby images of the moon and the Milky Way leaving just 9 deep sky images and one of those is particularly rubbish! We all must have a masochistic streak!! My rig gets taken down next week and packed away until August - lets hope for a better season next year.

But whilst China have reopened, manufacturers are struggling with high demand, materials shortages and reduced shipping channels. A perfect storm! In an attempt to stay on top of the situation 'everyone' at FLO is working overtime. My own working day starts at 5am, seven days a week, and has done for a while.

I've been using my Tak 100 refractor to observe double stars this evening but I noticed that the sky transparency was quite good so I've also been challenging the scope and myself to see how many galaxies I can spot. I thought I was doing well in finding 11 in Leo, and quite a few in Coma Berenices, Virgo and Canes Venatici. The brighter ones were looking really quite contrasty for a small aperture scope. I was going to have a look at the Markarian's Chain of galaxies on the Virgo / Coma B border but m

Consisting of nine overlapping panels of colour with the Askar200/ASI2600mc totalling 7.5hrs and eleven panels of Ha with the Samyang135/ASI1600mm totalling 9hrs. I've added high resolution data from Esprit100/X46 and Esprit150/SX46 images to the M78, Horsehead and M42 areas.

  30. M31 was the object for my first light with the RASA 8 and ASI2600MC back in August. Last night I finally got around to collect some Ha for it. Collected with a dual band filter (IDAS NBX) but I only used the red (Ha) channel. The data was added to the red channel in the RGB image as blend mode Lighten in PS. I think that the Ha clearly lifted the colours of the galaxy in a pleasing way. For the RGB data I have tried to tame the enormous dynamic range of this object so I could both bring out the outer dust "cloud" (presumambly made up my stars) that is often missed (or outside the FOV) as

  31. As luck would have it I got a couple of hours under the sky when the camera arrived. Paired with my Sharpstar 94EDPH and 0.8x FR, this is two hours of data in 300s subs and a few 30s subs to fill in the trapezium region. Its a bit noisy in the dark areas, to be expected with the short integration time, and stars are bit big (processing and focus), but otherwise promising C+C welcome Adam

  32. Hi all, Last week I've put together some of my data made the last couple of months to compose this bi-colour image of M27. Quite tricky to proces due to the high dynamic range of the object, quite a pain to tease out the faint outer details without making the image look to forced. I started the processing job from scratch a couple of times, but settled with this version for now. The h-alpha data was acquired from my heavily light polluted backyard, the o3 data I acquired during an astro holiday in Southern France (Provence) under pitch black skies late August.

His fascination with the night sky increased significantly when in his teens he upgraded his wobbly department store telescope (gifted to him as a child) to a 6" Newtonian. He later studied astronomy at University of Hertfordshire where he met his wife, Bella, on their very first day. After Uni Chris worked in radiology while Bella now works in the editorial department at the Royal Astronomy Society. Chris appeared on our radar when he

  36. It's that time of year where we're seeing this pop up a lot. I think this will be the last broadband image until later in the year. Just 19 x 300s Lum and 6 x 300s each of R, G and B on the last clear night recently. Taken with my RedCat and an Atik 460EX. The lack of data is showing at full resolution (e.g. M86) but I've left it anyway. I'm loving M88 and some of the smaller NGC galaxies. Captured with Voyager, calibrated & stacked in APP and processed in PixInsight. Thanks for looking! @Rob63 showed a similar markup to the one below in another thread

Moonrise was 8:40PM, as it rises its light washes out the detail in the galaxy. Taken with the Samyang 135mm f2 and Canon 6d, using just 10 second exposures. I processed the first frame in PS (mostly using Noel's actions) then used batch processing to apply the same workflow to all 360 frames. Hope you like it, more details here if anyone is interested.

  38. The Volcano Nebula is Nr 3 in the Mandel-Wilson Catalogue of Integrated Flux Nebulae (IFN). IFN is a very faint type of nebulosity that is thought to be diffusely and collectively energized by all the stars in the galaxy rather than a single star (like in reflection nebulae). It is therefore very faint and is best imaged with a rather large parture short focal lenght telescope (i.e. with a low f-value), like the RASA 8, and a relaively long total integration time. Then a dark site is also needed. My SQM showed 21.4 on this night and the lack of major mishaps and clouds allowed me to collect 8.

I have been at the lookout for a wide field scope (what some people call astrographs) and this spring I came across a nearly unused RASA8, and after 6 months waiting time, due to the virus situation, I finally received an ASI2600MC - an APS-C sized cooled OSC with relatively small pixels (3.76 µm) that kind of fit the 400 mm FL of the RASA8 (ca 2 "/pix sampling). As I allready had my two obsies filled up with other scopes I decided to spend the summer building a third obsy for the RASA to put on my long-time retired NEQ6, my first mount bought in 2014 when I started my AP adventure, but having

On the one hand we want to punch the air (this has been a record year of growth for FLO) but that doesn't feel appropriate knowing how many businesses have closed or are hanging on with their fingernails. And of course the considerable impact on our health and freedoms during this global pandemic. This year has however shown us how dependent we are on each other and key workers. Like supermarket and corner-shop staff, postal workers, delivery drivers, refuse collectors, etc. And of course hospital and care home

So as I was shooting away on NGC6914 with my double Esprit rig in obsy 1 (posted earlier today), I got the RASA 8 up and running again on my old NEQ6 in obsy 3, aimed at some dark nebulosity near the Iris nebula. Had the ASI2600MC set at gain 100 and -10°C. Got 235 x 2 min so 7.8 hours, which is a lot of photons at f/2. Took a few hours to stack in PI. Most processing done in PS. I think there is same drama in the image where dark forces appear to head toward the loverly Iris. I believe

So I already gave my hopes up a bit when yesterday evening I noticed it was clearing up. Against my feeling I decided to just build up the equipment and see what would happen. Somehow I was lucky and while there was lightning in the distance the sky kept clear right over my head until about 4 in the morning. So I decided to work on some dark nebulae as they are impossible to image from my home location. I used my setup

Big targets captured with a huge focal lenght. For this image was 2050mm FL. The C11" Edge HD has a great corrected field and no crop is needed. Astrophysics CCDT67 do the job puting telescope in a faster f/7 ratio and no distortion applied. It's not so easy in this FL to run 600s subs in a intermediate mount like AZ-EQ6 with 70% payload reached. I had time to play side by side with the famous Hubble version!

  50. Finally got started for the season and had a few nice nights in mid august. Still fighting some problems with spacing and/or tilt but I think it turned out all right anyway. I have two suspects and don´t quite know how to identify the culprit Either the TS 2" flattener is not that good or I have focuser tilt. I think. The search will continue. Rotating the camera 90 degrees gave deformed stars in the same corners as before rotating... so that might indicate what? The flattener since it rotated with the camera? Anyway, hope you like the image. IC1318, Gamma Cygni Nebula. Ha: 41*5 min
