Hi Alex

Thank you for your kind comments. I think this is a great idea and hopefully, an inspiration, (thanks to your efforts and perserverence), to all those who might, as I did, still doubt the capability of their 'scope; be it an 8" or lesser aperture; to take images.

For my part, I am quite willing to post a few I have made over the past few years, but I'm afraid, with an absence of any flair for record keeping, I can't tell you with any certainty, whether they were taken using my N8i or my 4" refractor; whether any focal reducer was used; or whether the camera employed was a DSLR or a Meade DSI. What I can say is that unlike you, I had virtually no success imaging from the standard Alt./Az. mount and as such mine have been taken using a GEM. You however, have shown that Alt./Az imaging CAN be done !

Best regards,
Tel

Hi Alex
is the imaging done with the Tring adapter or mounted dslr with a lens?

Thank you for posiing the Plato images, Alex. One of my goals with my 10 inch Dob. has been to photograph the craterlets. I did it this month with the new Nexstar 130 I got for my grandson. I digiscope from snowflakes to birds, and to the moon with my LX3 and 5 Hyperions. Afocal mode.

Do not understand your use of the XSi. Was it without a lens and using the projection from the 8mm Hyperion? If so, what was the approximate spacing from the E.P. to the camera?

With the 130 I used a 5mm E.P. with a 2X Barlow. I was only able to see 2 or 3 craterlets by eye, but was pleased that I could photograph the 4. Not quite as good as you did, however. 130 is a great scope. Could not have done it without guidance. Thanks. Gene smithhill1@gmail.com

Hi Alex,

I can't match your superb "Plato", but here's an attempt from around the night of the 25th May, (I told you my record keeping was abysmal) ! :lol: It might be my imagination but I think there is just a hint of a couple of craterlets. (?)

Equipment etc. as remembered:

200 Frames @ Prime Focus (f/10) using a Meade DSI. Nexstar 8i OTA on Skywatcher HEQ5 Pro. Stacked in Nebulosity and processed in Photoshop CS2.

Best regards,
Tel

Hi Alex,

I came across this one of Comet Holmes from my collection which, if I recall, I took back around the end of October 2007 when the whole thing virtually exploded or at least expanded very rapidly. I do recall this was shot using my standard alt./az. Nexstar 8i mount in conjunction with a Meade DSI but as always, I can never remember the exact settings. I may however have used a Celestron f/6.3 or an f/5 Antares reducer.

Best regards,
Tel

NexStar 8SE, Canon XSi, 340x 10 second samples at ISO 1600. About half was selected by DSS for stacking. This is around 30 min worth of exposure. Levels and curves applied in Photoshop. Carboni's tools used to remove "Space Noise" and increase "Local Contrast".

The specific objective was to discern irregularities in the dust lanes. At that the experiment failed. But I believe I see enough promise in the data that this can be achieved with 8SE.

Still an excellent shot of the "Sombrero", Alex. It always amazes me how these images hold together when stacked with no or very little evidence of field rotation when you take for example this photo in itself: 340 frames at 10secs. each ! OK, so only around 50% were useful, (par for the course IMO), but nevertheless ---- ! Superb once again ! Many congratulations :bow: :bow:

For my part, just to add to your list, I produced this one of M13 on Thursday night. ( OK,I know it's an easy target, but with our weather, I'm in sore need of practice !) :rofl2:

Conditions, (this time noted), as follows:

Clear skies with good seeing and reasonable transparency.
Camera: Canon 350D. 10 Frames. Exposure 60s. at f/10
OTA: N8i 2032mm.
Mount HEQ5Pro.
Captured and stacked in "Nebulosity". Processed in PSCS2.

Best regards,
Tel

Here is comparison of 8SE M104 with the Hubble. Left one is HSTs M104 overlaid on top of 8SE at 50% opacity. Right one is 8SE only.

Considering the slight advantages the Hubble has over your ground bound observation site, I would say you are not doing too badly :grin:
